Question

The number of amino acids in casein fibre is

• A. 20
• B. 18
• C. 16
• D. 14

Hint:

There are 20 standard amino acids that make up proteins.

Answer 1

The Correct Option is B

Casein protein is composed of 18 common amino acids. While there are 20 standard amino acids found in most proteins, casein lacks two of them. It's important to remember that even though it has 18 amino acids, their specific arrangement and proportions vary, giving rise to different types of casein proteins (like alpha, beta, and kappa casein).
