540,000 (5.4X10^5)

Explanation:

kj means Kilojoules, while we are converting to joules.

Determine the correct amino acid sequence of a heptapeptide (a small peptide containing seven amino acids) on the basis of the f
vova2212 [387]

Answer:

a. Leu-Ala-Arg-Phe-Val-Val-Lys .

Explanation:

Hello.

In this case, considering the given data, we notice that the amino acid has a N-terminal Leu, that is why we first discard d. Moreover, considering the data (iii) and (v) we can infer that there are going to be two fragments by which it is possible to reason the proper sequence:

(iii): the amino acid has one section composed by Lys-Phe-Val-Val and another one by Ala, Arg, Leu that is why e is also discarded.

(v): the other two fragments are Ala, Arg, Leu, Phe, that is why b is discarded.

(iii) and (v): given the aforementioned fragments, we can combine them and therefore discard c, that is why the correct sequence is:

a. Leu-Ala-Arg-Phe-Val-Val-Lys .

Best regards.

Electrolytes are liquid or molten substances that are able to conduct electricity.

they conduct electricity by the use of their ions in solution.

Since acid and bases ionize in solution, they will conduct electricity.

An acid is a substance that produces excess hydroxonium ion in solution.

A base produces excess hydroxyl ions in solution. Hope This Helps!
