Question

Assertion: $\alpha$ -amino acids are the building blocks of proteins.
Reason: Natural amino acids are mostly $\alpha$ -amino acids.

• A. Both A and R are true and R is the correct explanation of A
• B. Both A and R are true but R is not correct explanation of A
• C. A is true but R is false
• D. A is false but R is true

$\alpha$-amino acids are the building blocks of proteins.
Proteins on hydrolysis exclusively give $\alpha$-amino acids.
Amino acids can be classified into $\alpha ,\beta ,\gamma$, etc.
Natural amino acids are mostly $\alpha$ -amino acids.
