To solve the question, we need to analyze both the Assertion (A) and the Reason (R) provided. ### Step 1: Understand the Assertion (A) The assertion states that "All naturally occurring alpha-amino acids except glycine are optically active." - **Optical Activity**: A compound is optically active if it can rotate plane-polarized light. For a compound to be optically active, it must have a chiral center (a carbon atom bonded to four different groups). - **Glycine**: Glycine is the simplest amino acid with the formula NH₂CH₂COOH. It does not have a chiral center because its two hydrogen atoms attached to the alpha carbon are identical. Therefore, glycine is not optically active. - **Other Alpha-Amino Acids**: All other naturally occurring alpha-amino acids (like alanine, valine, leucine, etc.) have a chiral center and are optically active. ...

Protein are nitrogeneous organic compound having very high molecular mass. They are polyamide formed from alpha -amino acid. The bond formed between two amino acid is called peptide bond (-underset(O)underset(||)C-NH-) . The product obtained by this peptide bond formation are called peptide and they may be divided as di, tri, tetra, penta peptide. Consider following statements concerning protein. 1. All amino acids which are constituents of proteins are alpha -amino acid. 2. alpha -amino acids are all optically active and have L-configuration. 3. An especially favourable conformation for the peptide linkage in protein is the alpha -helix arrangement . 4. alpha -amino acids are connected by ester linkage.

Tartaric acid [HO_(2)CCH(OH)CH(OH)CO_(2)H] was an important compound in history of stereochemistry. Two naturally occuring forms of tartaric acid are optically inactive. One optically inactive form (P) has a melting point of 210- 212^(@) C and can be separated into two optically acitve forms, whereas other optically inactive form (Q) cannot be resolved further. Optically inactive form Q is
