how to remove an amino group from an amino acid to form pyruvate or acetyl coa?

Answers

Answer 1

To remove an amino group (-NH₂) from an amino acid and convert it to pyruvate or acetyl CoA, a process called deamination.

Deamination involves the removal of the amino group from the amino acid, resulting in the formation of ammonia (NH3) and a keto acid. Pyruvate is a keto acid, while acetyl CoA is derived from a keto acid through a further series of reactions.

There are two main pathways by which deamination can occur in the body: Transamination: In this pathway, the amino group is transferred from the amino acid to an alpha-keto acid, resulting in the formation of the new amino acid and the new keto acid. The enzyme responsible for this reaction is called transaminase or aminotransferase. Pyridoxal phosphate (PLP), a derivative of vitamin B6, is a cofactor required for this reaction.

Oxidative deamination: In this pathway, the amino group is directly removed from the amino acid and transferred to a molecule of oxygen, resulting in the formation of ammonia and a keto acid. The enzyme responsible for this reaction is called deaminase, and it requires the presence of molecular oxygen.

Once the amino group has been removed from the amino acid, the resulting keto acid can be further metabolized to form pyruvate or acetyl CoA through a series of additional reactions in various metabolic pathways, depending on the specific amino acid and the conditions of the reaction.

which of the following reactions of alkenes is stereospecific? question 7 options: addition of hcl (treatment with hcl) hydrogenation (treatment with h2/pt) addition of hbr (treatment with hbr) acid-catalyzed hydration (treatment with aqueous h2so4)

Answers

Among the given reactions of alkenes, the reaction of addition of HBr (treatment with HBr) to an alkene is stereo-specific.

What is stereo-specific?

Stereo-specificity is a chemical concept that describes a reaction's capability to differentiate between stereo-isomers. A stereo-specific reaction is one in which only one stereo-isomer is generated from a given stereo-isomeric reactant. The stereo-chemistry of the reactant, the product, or both is generally associated with stereo-specificity. Stereo-specific reactions are also referred to as stereo-selective reactions.

When an alkene reacts with HBr in the presence of a peroxide initiator, the hydrogen (H) and the bromine (Br) atoms add to the carbon atoms of the double bond in a syn addition. This means that the hydrogen and the bromine atoms are added to the same side of the double bond, resulting in the formation of a single product with a specific stereo-chemistry.

Therefore, the reaction of addition of HBr to an alkene is stereo-specific, because the stereo-chemistry of the product is determined by the syn addition of the hydrogen and the bromine atoms to the double bond. The other reactions listed are not stereo-specific.

(1pts) 1. hg2cl2 and hgcl2

Answers

The reagent that could be added that would allow you to differentiate between the members of each pair of solid compounds below is the Sodium Thiosulfate (Na2S2O3) reagent.

Let's take a look at the process: Na2S2O3 can be used to distinguish between HgCl2 and Hg2Cl2. They react differently with Na2S2O3 due to the fact that they have different stabilities as mercuric and mercurous compounds. In the presence of HgCl2, Na2S2O3 quickly precipitates yellow-colored Hg2Cl2, which can be readily detected.

The balanced equation for this reaction is as follows:

HgCl2 (s) + Na2S2O3 (aq) → Hg2Cl2 (s) + NaCl (aq) + Na2S2O4 (aq)

Therefore, when Na2S2O3 reagent is added to HgCl2 and Hg2Cl2, Hg2Cl2 precipitates as a yellow-colored precipitate while HgCl2 does not form any precipitate.

Calculate the empirical formula for a compound with 4 atoms of carbon for every 12 atoms of hydrogen

Answers

The compound's empirical formula is CH₃, which stands for one carbon atom and three hydrogen atoms.

What is compound?

A compound is a material that is created chemically by combining two or more separate elements in a specific order. Chemical bonds, which may be ionic or covalent in nature, are what hold the constituent parts of a compound together. Many chemical processes, such as synthesis (combining of elements), decomposition (dissolving a compound into its component elements), and exchange, can result in the formation of compounds (replacement of one element in a compound by another).

Assuming that there are 4 carbon atoms and 12 hydrogen atoms, we can calculate the carbon to hydrogen ratio as follows:

By dividing both sides by 4, the ratio of carbon atoms to hydrogen atoms, which is 4:12, can be reduced to 1:3.

This indicates that the chemical has three hydrogen atoms for every one carbon atom.

As a result, the compound's empirical formula is CH₃, which stands for one carbon atom and three hydrogen atoms.

The compound that will undergo a faster hydrolysis reaction by the SN1 mechanism is [tex]CH_{3} CH_{2}CH_{2}Cl[/tex] (option B).

What is the SN1 reaction?

SN1 is a kind of nucleophilic substitution reaction that is unimolecular, which means that the reaction's rate is only dependent on the concentration of a single molecule, the reactant. A unimolecular reaction is one in which the rate-determining step is the dissociation of a single molecule. SN1 reactions are unimolecular in nature and proceed in two steps. In the first step, the substrate undergoes heterolysis to form a carbocation and a halide ion. In the second step, the carbocation is attacked by a nucleophile, which can be either neutral or negatively charged.

SN1 mechanism reactions occur when a polar protic solvent is used, which means that the solvent must be able to stabilize the carbocation intermediate that is formed during the reaction. This is the case when the solvent is water, which is polar protic.

when we were doing the gc analysis of our product from dehydrobromination of 2-bromobutane, we commonly saw a large peak at the very beginning of the gc spectrum. what is the peak?the desired compound should be significantly more soluble in one solvent than the other.the solvents should be more basic than the desired compound.the two solvents should have significantly different polarity.

Answers

The large peak at the very beginning of the GC spectrum during the analysis of the product from dehydrobromination of 2-bromobutane is likely due to the presence of the solvent used for the extraction of the product.

During the extraction process, it is common to use a polar solvent, such as diethyl ether or ethyl acetate, which can dissolve the desired compound (in this case, an alkene) and separate it from the byproducts and impurities.

However, some of the polar solvent used in the extraction process may carry over to the GC column and be detected as a large peak at the beginning of the GC spectrum. This peak is often referred to as the solvent peak and can interfere with the analysis of the desired compound, making it difficult to accurately determine its concentration.

To minimize the impact of the solvent peak on the analysis, it is important to use a solvent that is significantly more soluble in one phase than the other. This is achieved by choosing solvents that have significantly different polarities or by using solvents that are more basic than the desired compound. The difference in solubility between the two phases allows for effective separation and minimizes the carry-over of the solvent into the GC column, reducing the interference of the solvent peak in the analysis of the desired compound.

Answers

3.16 µg of Polonium 210 is needed as LD50 for the victim.

The Lethal dose 50 (LD50) of Polonium is 0.045 micrograms (µg) per kilogram (kg) of body weight. The average weight of an adult is 70 kg.

LD50 dose of Polonium = 0.045 µg/kg × 70 kg = 3.15 µg

Assuming the Polonium isotope has a purity of 100%, the atomic mass of Polonium (Po) 210 is 210,

the molar mass of Polonium is:

Molar mass (Po) = 210 g/mol

Moles of Polonium = LD50 dose / molar mass = 3.15 × 10-6 g / 210 g/mol = 1.5 × 10-8 mol

The mass of Polonium needed to deliver an LD50 dose to the victim is:

Mass of Polonium = Moles × Molar mass = 1.51 × 10-8 mol × 210 g/mol = 3.16 × 10-6 g = 3.16 µg

Therefore, 3.16 µg of Polonium is needed to deliver an LD50 dose to the victim.

How many mL of a 0.320-molar solution of sucrose in benzene (density = 0.8787 g/mL) are needed to have 0.160 moles of sucrose?
(a) 500 mL
(b) 498 mL
(c) 438 mL
(d) 567 mL
(e) 219 mL

Answers

Answer:

(e) 219 mL

Step-by-step explanation:

The molar mass of sucrose is 342.3 g/mol.

The number of moles of sucrose needed is:

0.160 mol

Using the molarity equation, we can find the number of moles of sucrose present in 1 L of the solution:

0.320 mol/L = x mol/1000 mL

x = 0.320 mol/L × 1000 mL = 320 mol/mL

The mass of sucrose needed is:

0.160 mol × 342.3 g/mol = 54.77 g

Using the density equation, we can find the volume of the solution needed:

density = mass/volume

volume = mass/density = 54.77 g/0.8787 g/mL = 62.37 mL

Therefore, the answer is (e) 219 mL (rounded to the nearest whole number).
Final answer:

Using the concept of molarity, 0.160 moles of a 0.320-molar sucrose solution in benzene corresponds to 500 milliliters of the solution.

Explanation:

To solve for the volume of the sucrose solution in benzene, we apply the definition of molarity (M) which is moles of solute divided by liters of solution. Since we're dealing with molarity, it's important to note that the density of benzene isn't necessary for our calculation.

Using the molarity equation (M=moles/L), we substitute the given values. So, 0.320 M = 0.160 moles / volume in liters. When we rearrange the equation to solve for the volume, we find that volume = 0.160 moles / 0.320 M. Hence, the required volume is 0.5 liters. Given that 1 Liter = 1000 milliliters (mL), we find the answer to be 500 mL. Therefore, (a) 500 mL is the correct answer.

The R-group may be anything from a simple hydrogen atom to a complex ring structure.Functional group in aspartic acidAmino acids, such as aspartic acid, have an -NH₂ group attached to the alpha-carbon and an -OH (hydroxyl) group attached to the carboxyl group (also called the acid group).

A functional group is a collection of atoms or groups of atoms in a molecule that gives it characteristic properties. The -OH group is referred to as the carboxyl group since it contributes to the acidity of the molecule in the case of aspartic acid.The peptide bond between two amino acids is formed when the carboxyl group of one amino acid reacts with the amino group (-NH₂) of another amino acid.

The removal of water from the two amino acids results in the formation of a covalent bond known as a peptide bond. This process is known as dehydration synthesis. When aspartic acid reacts with another amino acid to form a peptide bond, the carboxyl group of aspartic acid acts as the donor, while the amino group of the other amino acid acts as the acceptor.

As a result, a carboxyl group is formed when aspartic acid reacts with another amino acid to form a peptide bond.

Answers

The pH that an acid will produce in solution will decrease the stronger the acid is. The negative logarithm of the concentration of hydronium ions is used to calculate pH.

What influences how strong acids and bases are?

An acid's relative strength can be anticipated based on its chemical composition. An acid is often more powerful when the H-A bond is more polar. Additionally, acidity increases with weaker H-A bonds and more stable conjugate bases like A.

What impact does an acid's or base's strength have on its conductivity?

Strong electrical conductivity indicates that an acid or base is a strong acid or base. A weak acid or base is one that conducts electricity only slightly. Demonstration of Acid and Base Conductivity: Using a light bulb equipment, the instructor will measure the conductivity of several solutions.

Answers

Question 1:

The balanced equation is:

3 Cu + 8 HNO3 → 3 Cu(NO3)2 + 2 NO + 4 H2O

From the equation, we see that for every 8 moles of HNO3, 4 moles of H2O are produced.

So, for 15.4 moles of HNO3, we can calculate the moles of water produced as follows:

Moles of H2O = (15.4 mol HNO3 / 8 mol HNO3) x 4 mol H2O

Moles of H2O = 7.7 mol H2O

Now, we can use the molar mass of water (18 g/mol) to calculate the mass of water produced:

Mass of H2O = 7.7 mol H2O x 18 g/mol

Mass of H2O = 138.6 g

Rounding to the nearest tenth, the answer is 138.6 g of water.

Therefore, when 15.4 moles of HNO3 are consumed, 138.6 g of water can be made.

Question 2:

The balanced equation is:

C + 2 H2 → CH4

From the equation, we see that for every 1 mole of C, 1 mole of CH4 is produced.

So, for 5.7 moles of CH4, we need 5.7 moles of C.

Now, we can use the molar mass of carbon (12 g/mol) to calculate the mass of carbon required:

Mass of C = 5.7 mol C x 12 g/mol

Mass of C = 68.4 g

Rounding to the nearest tenth, the answer is 68.4 g of carbon.

Therefore, 68.4 g of carbon are required to produce 5.7 moles of methane
