Assertion: All naturally occuring `alpha`-amino acids are optically active
Reason: Most naturally occuring amino acids have D-configuration.

In the following questions a statement of Assertin (A) followed by a statement of Reason (R) is give. Choose the correct answer out of the following choices. Assertion (A): All naturally occurring alpha -amino acids except glycine are optically active Reason (R): Most naturally occuring amino acids have L-configuration.

Assertion (A) All naturally occurring alpha -aminoacids except glycine are optically active. Reason (R) Most naturally occurring amino acids have L-configuration.

Assertion (A) All naturally occurring alpha -aminoacids except glycine are optically active. Reason (R) Most naturally occurring amino acids have L-configuration.

Except glycine all other naturally occurring amino acids are optically active.

Which amino acid is not optically active?

Assertion: Except glycine, all naturally occurring alpha -amino acids are optically active. Reason : All alpha -amino acids occurring naturally except glycine has at least one asymmetric carbon.
