NURSING ANM AND GNM

Detailed explanation-1: -The carbon, carboxyl, and amino groups are common to all amino acids, so the R-group is the only unique feature in each amino acid. (A minor exception to this structure is that of proline, in which the end of the R-group is attached to the -amine.)

Detailed explanation-2: -The R group for each of the amino acids will differ in structure, electrical charge, and polarity.

Detailed explanation-3: -An R-Group is a side chain attached to the -carbon of all amino acids. It decides the chemical versatility of the amino acid. For example, some R-Groups carry a charge, creating a polar molecule. Some R-groups are hydrophobic or hydrophillic.

Detailed explanation-4: -Amino acids have the same base structure, which is important for proper chemical bond formation between adjoining molecules. Each amino acid has a central carbon designated as the -carbon. The -carbon always has the following four groups attached to it: –NH2 a basic amino group.
