Question

Fish proteins are considered nutritionally superior to most vegetable proteins because they are rich in

• A. All the $20$ amino acids
• B. Essential amino acids
• C. Peptide bonds
• D. Polypeptides

Answer 1

The correct option is B Essential amino acids

Proteins are made up of amino acids, although the amount and type of each amino acid varies based on the protein source. Animal protein sources (fish, eggs, poultry, dairy) are the highest quality protein sources as they contain all (20) the essential amino acids. Plant sources lack one or more amino acids and thus are incomplete source of protein.
