Question

Assertion :Amino acids are called $\alpha$ -amino acids. Reason: Amino acids are organic compounds containing an amino group and an acidic group as substitutes on the $\alpha$. -carbon

• A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
• B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
• C. Assertion is correct but Reason is incorrect
• D. Both Assertion and Reason are incorrect

Answer 1

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion

Amino acids found in the human body are always α-amino acids because, in an amino acid carbon, its four attached groups are - COOH, - NH2, -H and a variable -R group. thus according to the nomenclature of organic compounds, we find that -COOH will be given preference thus numbering of compound starts from there and after that - the NH2 group is attached on α carbon of the amino acid so called as alpha-amino acid.

Thus, both assertion and reason are true and the reason is the correct explanation to the given assertion.
