Consider the following statements concerning proteins I. All natural amino acids which are constituents of proteins, are alpha -amino acids. II. alpha -Amino acids are all optically active and have L-configuration. III. alpha -Amino acids are connected by ester linkages. IV. Favourable conformation for the peptide linkages in protein is the alpha -helix arrangement. Of these statements
