The magical skill of peptide to human body

The emergence of peptides in the skin care industry undoubtedly opens a door to anti-aging skin care, and what detailed cognition we need to make for peptides! A skin care product with good ingredients has obvious effect on the skin for a long time!

Peptide is a kind of compound formed by covalent connection of two or more amino acids through peptide bond, which widely exists in nature and living organisms. Peptide is one of the important material bases of life, and it plays an important role in the process of life. With the development of peptide manufacturing technology, more and more expensive peptide products in the past have entered people's daily life, especially in the field of cosmetics. Peptide has become a very important active ingredient in anti wrinkle and anti-aging, and also plays an important role in whitening, promoting hair growth, antibacterial and other aspects. 1、 Structure and nomenclature of polypeptides

Peptide is a kind of compound which has amino acid residues connected with each other by amide bond. The amide bond in polypeptide molecule is called peptide bond. Generally, it is the formation of one or two sex ions formed by the dehydration and condensation of one amino acid's α - COOH and another amino acid's α - NH2

In polypeptide chain, amino acids are arranged in a certain order, which is called amino acid order. The peptide formed by water loss of two amino acids is called dipeptide, the peptide formed by water loss of three amino acids is called tripeptide, and so on... The peptide formed by water loss of multiple amino acids is called polypeptide, and the peptide composed of more than 50 amino acids is called protein.

Each peptide has a free -NH, called Amino terminal, also known as N- or H terminal; a free -COO-, called Carboxyl terminal, also known as C- terminal or OH terminal. Generally, N-terminal amino acid abbreviation is written on the left, C-terminal amino acid abbreviation is written on the right, and each amino acid name is connected with a short line in the middle.

The name of polypeptide generally takes the amino acid containing complete carboxyl as the parent, which is called a certain amino acid; the name of other amino acids in the peptide chain is changed from acid to acyl, and the amino acid containing N-terminal is written at the front, and then it is arranged to the amino acid containing C-terminal according to their order in the chain. 2、 Classification and function of polypeptides

At present, the polypeptides used in cosmetics can be divided into hydrolyzed protein and functional polypeptides according to different sources and functions.

Hydrolyzed protein peptide is the hydrolysate of animal and plant protein. It is a multi-component mixture with amino acid as the main component and a certain amount of oligopeptide. It is mainly used for moisturizing with no other specific functions, such as hydrolyzed collagen peptide from animal skin and hydrolyzed oat peptide from plant.

Functional polypeptides, also known as "beauty polypeptides" or "active biological polypeptides", are small molecular compounds with specific amino acid sequence, single structure and clear mechanism of action, most of which have molecular weight less than 1000. Functional polypeptides have high biological activity and biodiversity, mainly experience in participating in the synthesis and catabolism of proteins in organisms, and can be actively regulated The synthesis and secretion of proteins inside and outside the ganglion cells ensure the expression and replication of life genetic genes, enhance the metabolism of organism tissues and cells, and then regulate the growth and development, growth and maturity, aging and disease of the organism. Therefore, the function polypeptides in the skin include anti wrinkle and anti-aging, repair, whitening and spot lightening, anti allergy and soothing. The properties of functional peptide and hydrolyzed protein peptide are shown in the table below.
