A peptide is an organic compound made up of amino acids containing a carboxyl group and an amino group.
The carboxyl group of one amino acid and the amino group of another amino acid can synthesize a peptide, and the amide group formed is called a peptide bond. Two or more amino acids are dehydrated and condensed to form a number of peptide bonds to form a peptide chain, and multiple peptide chains can be folded to form a protein molecule.
A peptide is an organic compound made from the dehydration of an amino acid, containing a carboxyl group and an amino group, and is an amphoteric compound. An amino acid cannot be called a peptide, nor can a peptide be synthesized; it must be a compound of two or more amino acids linked by a peptide bond.
Peptide is an important biologically active substance for a variety of cellular functions in living organisms. All cells can synthesize peptide substances and their functional activities are regulated by peptides. It is involved in the fields of nerves, hormones, cell growth, reproduction, etc., and plays an important role in regulating the functions of various systems, organs and cells in the body.
