Two ways to synthesize peptides

20th Apr 2018

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...

Peptides Stability

19th Apr 2018

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...

​​Symmetric Anhydride Method for Polypeptide Synthesis

17th Apr 2018

Peptide Synthesis Symmetric Anhydride of Nα-alpha-acyl amino acid is an high-activity midbody for peptide bond formation. In contrast to the mixed anhydride method, it has no ambiguous regional selectivity with the reaction of the amine nucleophile...

The Mixed Anhydride Method for the Polypeptides Synthesis

16th Apr 2018

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...

The Basic Principles of the Formation of Peptide Bond

13th Apr 2018

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...

Carbodiimide Method for Polypeptide Synthesis

27th Nov 2017

The carbonimide compounds can be used in the condensation of amino and carboxyl groups. In this class of compounds, N'-DCC is relatively cheap and soluble in peptides to synthesize commonly used solvents. During the formation of peptide bonds, carbod...
