There are two main ways to synthesize peptides: chemical synthesis and biosynthesis. Chemical synthesis is mainly achieved by the condensation reaction of amino acids. In order to get the synthetic polypeptide with specific sequence, when the amino a...

A common misconception about peptides is that peptides are as unstable as proteins. In fact, polypeptides are much more stable than proteins, because the two factors that affect the stability of proteins do not exist in polypeptide synthesis. Th...

1. Inhibit cell degenerationPeptides can effectively inhibit cell degeneration and enhance human immunity, thus reducing the loss of collagen and improving skin relaxation.2. Activate cell activityBy activating cellular activity, peptides can effecti...

The formation of a peptide bond (which produces a dipeptide) is a simple chemical process on the surface. It refers to two amino acid components that are connected through the peptide bond (amide bond) and remove the water simultaneously.Under the co...

Both organic carboxylic acid and inorganic acid can be used in the formation of acid anhydride. However, only a few have been widely applied, and in most cases, alkyl chloroformate is used. Ethyl chloroformate used in the past is mainly substituted b...
