An amino acid short chain is known as a peptide. Peptide bonds are the connections that hold acids of peptide together in particular order. Characteristically, shorter length peptides helps to identify them from proteins. Different ways used classify peptides, including length, source or their biological functions. The fact serve several purposes suggests there foundation for improvement production and structure enhance action. In addition, many patents on therapeutic diagnostic approaches...
