Question

1. An amino acid molecule has the following structure.
H
NH
COOH
R
Which two of the groups combine to form a peptide link?​

Answer 1

$\sf{\underline\blue{Answer:-}}$

Amino acids are the monomers that make up proteins. Each amino acid has the same fundamental structure, which consists of a central carbon atom, also known as the alpha (α) carbon, bonded to an amino group (NH2), a carboxyl group (COOH), and to a hydrogen atom.

_______________________________________________________________

A peptide bond is a chemical bond formed between two molecules when the carboxyl group of one molecule reacts with the amino group of the other molecule, releasing a molecule of water (H2O). This is a dehydration synthesis reaction (also known as a condensation reaction), and usually occurs between amino acids.
