Q. 16.11 - An Introduction to General, Organic, and Biological Chemistry

Question

Draw the condensed structural formula for each of the following pairs, and give their three-letter and one-letter abbreviations:

a. alanylations

b. serylpheaylalanine

c. glycylalanylvaline

d. valyliwoleucyltrypeophan

Step-by-Step Solution

Answer

Peptide structures are given below, along with one-letter and three-letter amino acid abbreviations:

(Part a) 

(Part b) 

(Part c) 

(Part d) 

Step 1: Introduction(Part a)

Proteins are constructed from amino acids. These have one hydrogen atom and one amine group.$\left(-{\mathrm{NH}}_2\right)$, one carboxylic acid group  $(-\mathrm{COOH})$ as well as one side chain (R group) connected to the central carbon atom

The carboxylic acid's hydroxyl group and the amino group's hydrogen combine to form a water molecule and an amide linkage. A "peptide bond" is an amide bond formed between the carboxylic group of one amino acid and the amino group of another amino acid.

Step 2: Given data(Part a)

The one-letter and three-letter amino acid alanylations abbreviations are provided below to help you find the structures of peptides.

Step 3: Explanation (part a)

Step 4: Given data(Part b)

The one-letter and three-letter amino acid  serylpheaylalanine abbreviations are provided below to help you find the structures of peptides.

Step 5: Explanation (part b)

Step 6: Given data(Part c)

The one-letter and three-letter amino acid  glycylalanylvaline abbreviations are provided below to help you find the structures of peptides.

Step 7:Explanation(part c)

Step 8: Given data(Part d)

The one-letter and three-letter amino acid valyliwoleucyltrypeophan abbreviations are provided below to help you find the structures of peptides.

Step 9:Explanation (part d)
