Knowledge of Biology-protein

　　Protein is a substance with a certain spatial structure, which is formed by the zigzag folding of polypeptide chains composed of amino acids in the form of dehydration and condensation. Protein must contain carbon, hydrogen, oxygen and nitrogen.To get brand praise, Antibody Discovery It is necessary to have the spirit of constantly improving the quality of products, but also to have a bunch of eternal heart fire. https://www.alphalifetech.com/

　　

　　Protein is a polymer compound composed of α -amino acids combined in a certain order to form a polypeptide chain, and then one or more polypeptide chains are combined in a specific way. Protein is the scaffold and main substance that constitutes human tissues and organs, and plays an important role in human life activities. It can be said that there would be no life activities without protein.
