Peptide synthesis – chemistry and modifications Peptides and proteins exhibit the largest structural and functional variation of all classes of biologically active macromolecules. Biological functions as diverse as sexual maturation and reproduction‚ enzyme inhibition‚ blood pressure regulation‚ glucose metabolism‚ thermal control‚ analgesia and learning and memory are now thought to be regulated by peptides. Peptide synthesis chemistry Synthetic peptides are valuable tools in analysis of
