Solving the Sequence of an Oligopeptide From Sequence Analysis Data Analysis of the blood of a catatonic football fan revealed large concentrations of a psychotoxic octapeptide. Amino acid analysis of this octapeptide gave the following results: 2 Ala 1 Arg 1 Asp 1 Met 2 Tyr 1 Val 1 NH4 1 The following facts were observed: a. Partial acid hydrolysis of the octapeptide yielded a dipeptide of the structure C O C N H H COOH H3C CH3 CH3 C CH H3 N b. Chymotrypsin treatment of the octapeptide yielded two tetrapeptides, each containing an alanine residue. c. Trypsin treatment of one of the tetrapeptides yielded two dipeptides. d. Cyanogen bromide treatment of another sample of the same tetrapeptide yielded a tripeptide and free Tyr. e. N-terminal analysis of the other tetrapeptide gave Asn. What is the amino acid sequence of this octapeptide

Answers

Answer:

The amino sequence of an octapeptide can be determined by :

i.Amino acids present in the peptide

ii.By the behaviour shown by the treatment of these material with different biological and chemical reactions

As shown ammonium was released from the peptide,which shows that the peptide contains either Asn or Gln.

As there is presence of Asp in the amino acid analysis which indicates that the octapeptide contains Asp.

Acid hydrolysis hydrolyzes the peptide bonds which yields a Ala-Val  which is the result of partial acid hydrolysis.

Chymotrypsin is on the C-terminal side of the aromatic amino acids Phe, Tyr, and Trp. The peptide has Tyr which indicates that  the two present tetrapeptides after chymotrypsin treatment are fourth and eighth amino acids i-e N--Tyr-C and Tyr as the fourth amino acid and Ala-Val somewhere in the octapeptide

As Arg is only present on the C terminal side  of the Trypsin cleavage therefore Arg must be the second or the sixth amino acid for the two dipeptides to form as a result of arginine treatment of a tetrapeptide

Cyanogen bromide cleaves on the C-terminal side of Met residues. For free Tyr to be produced from cyanogen bromide treatment of one of the tetrapeptides, Met must be either the third or seventh amino acid. Because Ala was present in both tetrapeptides, Ala must be either the first or fifth amino acid, present in the same tetrapeptide as Arg and Met,i-e N.-Tyr-C and Ala-Val somewhere in the octapeptide and Ala-Arg-Met as the first, second, and third or fifth, sixth, and seventh amino acids and Tyr as the fourth amino acid.

One of the tetrapeptides contains Ala-Val as its second and third amino acids and Asn as its N-terminal amino acid. Therefore two combinations are possible as below

N-Asn-Ala-Val-Tyr-Ala-Arg-Met-Tyr-C or N-Ala-Arg-Met-Tyr-Asn-Ala-Val-Tyr-C

Answer:

The amino aciid sequence of an octapeptide can be determined from the amino acids that are present in the peptide and from the results of different chemical and biological treatments.

One equivalent of ammonium was released fro the peptide, indicating that the peptide contains either Asn or Gln. The presence os Asp in the amino analysis indicates that the octapeptide contains Asn.

A) Acid hydrolysis hydrolyzes peptide bonds. The dipeptide Ala-Val is obtained by partial acid hydrolysis. The indicates that Ala-Val is present in the peptide

B) Chymotrypsin cleaves on the C-terminal side of the aromatic amino acids. Phe, Tyr, and Trp. The peptide contains only Tyr. The presence of tetrapeptides after the treatment of ohymotrypsin indicates that Tyr is the fourth and eighth amino acids.

N-Tyr-C and Tyr present as the fourth amino acid. in constrast, Ala-Val is present in the octapeptide

C) Trpsin cleaves on the C-terminal side of Arg and Lys residues. only Arg is present in the octapeptide. Arg must be the second or sixth amino acid, for two dipeptide to be formed from arginine during the treatment of one tetrapeptide.

D) Cyanogen bromide cleaves on the C-terminal side of Met residues. For free Tyr to be produced from cynogen bromide treatment of one of the tetrapeptides, Met must be either the third or seventh amino acid. Because Ala is present in both tetrapeptides, Ala must be either the first or fifth amino acid, present in the same tetrapeptide as Arg and Met.

In addition, presence of N-...-Tyr-C and Ala-Val in the octapeptide and Ala-Arg-Met as the first, second, third or fifth, sixth or seventh amino acids and Tyr as the fourth amino acid.

E) One of the tetrapides contains Asn as its N-terminal amino acid, and Ala-Val as its second and third amino acids. Two octapeptides are possible from this peptide analysis.

The amino acid sequence of the octapeptide is the following:

N-Asn-Ala-Val-Tyr-Ala-Arg-Met-Tyr-C:

Convert 4.30×10^25 molecules of NH3 to moles please do step by step so I can Understand ​

Answers

Explanation:

Number of molecules: 4.30×10²⁵

We need to find out the total number of moles.

Now, as per Avogadro's law, 6.02×10²³ of anything (Avogadro's number) constitutes a unit called one mole. Just like 12 is a dozen, 6.02×10²³ is a mole.

If you were given 24 bananas and you had to find out the number of dozens, you would divide the total number of bananas (24) by the number of bananas in one dozen (12).

We do exactly the same here: divide the total number of molecules (4.30×10²⁵) by the number of molecules in one mole (6.02×10²³) to get the number of moles.

4.30×10²⁵ / 6.02×10²³ = number of moles

Solving, we get number of NH3 moles = 71.4 which is your final answer!

1. Is this reaction exothermic, endothermic, or neither.
2. If you said the reaction was exothermic or endothermic, calculate the amount of neat that was released or absorbed by the reaction in this case.
3. Calculate the reaction enthalpy AW per mole of NaOH.

Answers

Answer:

This question is incomplete

Explanation:

This question is incomplete because of the absence of the ALEKS Data's resource. However the steps required to answer questions that tests the heat of solution and heat of reaction are all the same.

1. The description provided in the question is an exothermic reaction; this is because exothermic reaction is a reaction that releases/gives off heat into the environment. The heat given-off here is what the student observed as "the temperature of the water rise from to over the course of minutes".

2. To calculate the amount of heat that was released/heat of solution (q) in joules;

q = m × Cg × (T2 - Ti)

where m = mass of water (can also be represented as volume)

Cg = specific heat capacity of water (4.184 joules)

T2 = final temperature of the solution

Ti = initial temperature of the solution

(T2 -Ti) is temperature change of the solution

3. Generally, enthalpy change for exothermic reaction is negative

Hence the formula for enthalpy change/heat of reaction (ΔH);

ΔH = - (q/1000 ÷ number of moles of solute)

Where q is the heat of solution determined in (2) above

number of moles = mass/molar mass of solute

molar mass of NaOH = 23 + 16 + 1 = 40 g/mol (where Na = 23, O = 16 and H = 1)

Other than lowering the cost of producing coins, what could be another added benefit of changing the metals used to make coins?(hint: think of the density...why would a metal that is less dense be beneficial?)

Answers

Answer:

See explanation

Explanation:

A coin is money made from metal stuff. Common coinage metals are copper, silver, nickel etc.

One consideration in coin production is the density of the coin. A coin of less density will have lesser mass and occupy a lesser volume. This makes it easier to carry the coin around.

Coins should therefore be made of low density metals so that they can easily be carried about.

A sample of gas is placed into an enclosed cylinder and fitted with a movable piston. Calculate the work (in joules) done on the gas if it is compressed from 13.43 L to 6.87 L with a pressure of 1.91 atm.

Answers

Answer:

Work done = 664.69 J

Explanation:

Given data:

Work done = ?

Initial volume = 13.43 L

Final volume = 6.87 L

Pressure = 1.91 atm

Solution:

work done = W = -PΔV

ΔV = V₂- V₁

work done = w = -P(V₂- V₁)

Now we will put the values in formula.

W = - 1 atm (6.87 L - 13.43 L)

W = - 1 atm (-6.56 L)

W = 6.56 atm.L

atm.L to joule:

6.56 atm.L × 101.325 J / 1L.atm

Why do we assume that the color of the flame is due to the positive ion ?

Answers

Answer:

Any element placed in a flame will change its color. Atoms are made of positively charged nuclei, about which negatively charged electrons move according to the laws of quantum mechanics. Quantum mechanics constrains them to appear in various distinct patterns, called orbitals. (Orbitals are a lot like planetary orbits, but blurrier, so that you're never quite sure just where the electrons are.)

Left on their own, the electrons of an atom tend to relax into orbitals that leave the atom with the lowest possible energy--its ground state. Putting atoms into a flame, though, adds energy to the looser electrons farthest from the nucleus and pushes them into other orbitals. Eventually, these excited electrons drop back to where they ought to be, and in so doing, they release the energy they stored up as particles of light, called photons.

How is energy related to the change of state represented by the model?

Atoms gain energy as a solid changes to a liquid.
Atoms gain energy as a solid changes to a gas.
Atoms lose energy as a solid changes to a liquid.
Atoms lose energy as a solid changes to a gas.

Answers

The energy related to the change of state represented by the model is  atoms gain energy as a solid changes to a liquid. Thus option A is correct.

What is energy?

Energy is defined as the quantitative property that is imparted to a body or a physical system and is visible in the performance of work as well as in the form of heat and light.

It can also be defined as ability to perform work.

There are basically nine types of energy:

Thermal energyRadiant energyNuclear energyChemical energy Electrical energyMotion energySound energyElastic energyGravitational energy

There are two more forms of energy.

Potential energyKinetic energy

In terms of atomic randomness, the gas contains atoms with extremely high kinetic energies. Atoms in the solid are only vibrating where they should be. As a result, for a gas to become a solid, some energy must be lost within the atom.

Thus, the energy related to the change of state represented by the model is  atoms gain energy as a solid changes to a liquid. Thus option A is correct.

Answers

Answer:

Final volume=V₂ = 216.3 mL

Explanation:

Given data:

Initial volume = 120.0 mL

Initial temperature = -12.3 °C (-12.3 +273 = 260.7 K)

Final volume = ?

Final temperature = 197.0 °C (197+273 = 470 K)

Solution:

We will apply Charles Law to solve the problem.

According to this law, The volume of given amount of a gas is directly proportional to its temperature at constant number of moles and pressure.

Mathematical expression:

V₁/T₁ = V₂/T₂

V₁ = Initial volume

T₁ = Initial temperature

V₂ = Final volume  

T₂ = Final temperature

Now we will put the values in formula.

V₁/T₁ = V₂/T₂

V₂ = V₁T₂/T₁

V₂ = 120 mL × 470 K /260.7K

V₂ = 56400 mL.K /260.7K

V₂ = 216.3 mL

You are given a glass rod that is negatively charged and a pinwheel that has a negative charge. What will happen when the glass rod is brought close to the pinwheel? Why? ​

Answers

Answer:

they will repel each other

Explanation:

When these two are brought close to one another they will repel each other. This is similar to what happens with magnets, when two objects share the same polarity one object will create a repulsive force upon the second object and push it away. This repellent force is caused by an electric field from the same charged electrons in the atoms of the object. Since in this case both the glass rod and the pinwheel have a negative charge they will repel each other when they come into proximity of one another.
