All amino acids , except proline, have the same general structure. More than 300 amino acids are present in the cell, however, only 22 amino acids participates in the protein synthesis ribosomically. GENERAL PROPERTIES OF AMINO ACIDS:- They have a very high melting and boiling points. Amino acids are white crystalline solid substances. In tastes, few amino acids are sweet , tasteless and bitter. Most of the amino acids are soluble in water are insoluble in organic solvents. BASED ON NUTRITIONAL REQUIREMENTS ;- Essential Amino acids – amino acid that cannot be synthesized by the human
