NURSING ANM AND GNM

Detailed explanation-1: -Every amino acid also has another atom or group of atoms bonded to the central atom known as the R group (Figure 1). The name “amino acid” is derived from the fact that they contain both amino group and carboxyl-acid-group in their basic structure. As mentioned, there are 20 amino acids present in proteins.

Detailed explanation-2: -Proteins are long chains or polymers of a specific type of amino acid known as an alpha-amino acid. Alpha-amino acids are unique because the amino and carboxylic acid functional groups are separated by only one carbon atom, which is usually a chiral carbon.
