Question

What amino acid does each abbreviation stand for? (a) Phe (b) Ser (c) Asp (d) Gln (e) His (f) Gly (g) Tyr

Short answer

Question: Identify the full names of the following amino acids represented by their three-letter abbreviations: (a) Phe (b) Ser (c) Asp (d) Gln (e) His (f) Gly (g) Tyr Answer: (a) Phenylalanine (b) Serine (c) Aspartic Acid (d) Glutamine (e) Histidine (f) Glycine (g) Tyrosine

Step-by-step solution

(a) Phe

Phe stands for Phenylalanine, an essential amino acid with an aromatic side chain.

(b) Ser

Ser stands for Serine, a non-essential amino acid with a polar side chain containing a hydroxyl group.

(c) Asp

Asp stands for Aspartic Acid, a non-essential amino acid with a negatively charged, polar side chain.

(d) Gln

Gln stands for Glutamine, a non-essential amino acid with a polar side chain containing an amide group.

(e) His

His stands for Histidine, an essential amino acid with an imidazole group in its side chain, having both basic and aromatic properties.

(f) Gly

Gly stands for Glycine, a non-essential amino acid with the smallest side chain, containing only a hydrogen atom.

(g) Tyr

Tyr stands for Tyrosine, a non-essential amino acid with a polar side chain containing an aromatic ring and a hydroxyl group.
