Detailed explanation-1: -(d) Glycine is the simplest amino acid with an amino group adn a carboxyl group.
Detailed explanation-2: -Glutamic acid consists of a single amino group along with two carboxyl groups. Due to the presence of a carboxyl group on the side chain in addition to the positive inductive effect of the methyl group, it has an acidic nature.
Detailed explanation-3: -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-4: -Glycine (symbol Gly or G; (listen)) is an amino acid that has a single hydrogen atom as its side chain. It is the simplest stable amino acid (carbamic acid is unstable), with the chemical formula NH2‐CH2‐COOH.
