Peptide and Amino acid

Amino acid is the general name of a class of organic compounds containing amino and carboxyl. The amino acid which attached to α- amino group on α- carbon is α- amino acid. All the amino acids composing the protein are α- amino acids. Amino acid is a basic unit of biological function protein macromolecules and basic substance of composing proteins required by animal nutrition
Amino acid givs a specific molecular structure and morphology to protein, making which molecule having the biological activity. Protein is important active molecules in Organism, including enzyme catalyzed metabolism.

Amino acids is the most basic substance constituting proteins of the organism which related to life activities, it has close relation with life and biological activity. It has special physiological functions in antibody, and it is a kind of indispensable nutrients in living body. Generation existence and extinction of life are all related to protein, once lost , life would be gone . The basic units of protein are amino acids, so if the body lacks any kind of essential amino acids, it will lead to physiological dysfunction, affects the body's normal metabolism and leads to disease in final.

Peptide is a polymers form of two or more amino groups covalently linked by a peptide bond, the substance hydrolyzated incompletely by protein is peptide too. Based on different α- amino group number composed, the Peptide with 2,3,4α- amino group is respectively called dipeptides , tripeptides and tetrapeptides , the peptide containing 10 or less amino acids is called an oligopeptide, the peptide containing 10 more amino acids is called polypeptide. they are all called peptides in short. The amino acid in the peptide chain is not the free amino acids because of its amino and carboxyl groups in the peptide bond formation are combined out, so peptides and the amino acid in the protein molecules are referred to amino acid residue.

The function of peptides to the human body can be roughly summarized by the scientists as four words: inhibition, activation, restoration, promotion.

  • Inhibition - inhibite cell degeneration, enhance human immunity;
  • Activation- activate cell activity, effectively remove harmful free radicals;
  • Fixing - repair human variability cells, improve cell metabolism;
  • Promotion – promote and maintain normal cell metabolism.
The biggest feature of Peptide is the strong activity and diversity compared with other substances of the organism. Peptides are the source of researching on the origin, structure and function of the life, it is the foundation to study disease , physical characteristics and cells tissue. The academic experts of international biochemistry, life sciences and medicine agreed unanimously that: twenty-first century will be the century of the peptide. Peptide is the most sophisticated international science and technology, one of the most competitive areas.
