Question

Type of amino acids obtained by hydrolysis of proteins is:

• A. \(α\)- Amino acids
• B. \(β\)- Amino acids
• C. \(γ\)- Amino acids
• D. \(δ\)- Amino acids

Answer 1

The Correct Option is A

To identify the amino acid types from protein hydrolysis, one must understand amino acid structure and protein hydrolysis. Proteins consist of amino acid chains linked by peptide bonds. Hydrolysis breaks these bonds, releasing individual amino acids.

The options are:

• \(α\)-Amino acids
• \(β\)-Amino acids
• \(γ\)-Amino acids
• \(δ\)-Amino acids

The correct choice is \(α\)-Amino acids. Proteins are formed from \(α\)-amino acids, where the amino group (\(-\text{NH}_2\)) attaches to the alpha (\(α\)) carbon, which is adjacent to the carboxyl group (\(-\text{COOH}\)).

Amino acid nomenclature is based on the amino group's position relative to the carboxyl group:

• \(α\)-Amino acids: Amino group on the alpha carbon (first carbon).
• \(β\)-Amino acids: Amino group on the beta carbon (second carbon).
• \(γ\)-Amino acids: Amino group on the gamma carbon (third carbon).
• \(δ\)-Amino acids: Amino group on the delta carbon (fourth carbon).

Since proteins are composed of \(α\)-amino acids, protein hydrolysis primarily yields \(α\)-amino acids.

Consequently, the correct identification is:

• \(α\)-Amino acids
