Protein are nitrogeneous organic compound having very high molecular mass. They are polyamides formed from `alpha`-amino acid. The bond formed between two amino acid is called peptide bond `-underset(O) underset(||)C-NH-`. The product obtainded 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 of `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. Which of the following statement are correct?A. 1 and 3B. 1 and 2C. 2 and 3D. 2,3 and 4
