Application and development history of Glycine

The alias of glycylglycine is N-glycylglycine, the molecular formula is C₄H₈N₂O₃, CAS number 556-50-3, the appearance is white leaf-like crystals or flaky crystals, shiny, and the solubility in water at 25℃ is 13.4g/100ml, easily soluble in hot water, slightly soluble in ethanol, insoluble in ether. Used as a biochemical reagent, as a stabilizer for blood preservation and protein drug cytochrome C injection in biological research and medicine. Glycine is a peptide that generates amino acids after hydrolysis, which can repair the skin.

Application of Glycine in Products

1. Food: dairy food, meat food, baked food, pasta food, seasoning food, etc.

2. Medicine: health food, fillers, medical raw materials, etc.

3. Industrial manufacturing: petroleum industry, manufacturing, agricultural products, storage batteries, precision castings, etc.

4. Tobacco products: Can replace glycerin as a flavoring, antifreeze and moisturizing agent for shredded tobacco.

5. Cosmetics: facial cleanser, beauty cream, lotion, shampoo, facial mask, etc.

6. Feed: canned pets, animal feed, aquatic feed, vitamin feed, veterinary drug products, etc.

The role and development process of Glycine in skin care products

Good sleep can help our body better complete various metabolisms, so that body functions can be maintained and restored in time. Occasional insomnia may cause our pores to look larger the next day. Using diglycin skin care products can help shrink pores, because it is hydrolyzed to form amino acids for skin care.

   The end products of protein digestion in the digestive tract are mostly small peptides rather than free amino acids. Small peptides can be completely absorbed and enter the blood circulation in the form of di- and tripeptides. Small peptides play an important role in protein nutrition. In order for animals to achieve the best production performance, a certain amount of small peptides must be needed. With the deepening of protein and amino acid nutrition research, people have gradually realized the importance of peptide nutrition. The intestine can transport diglycine intact. The simplest peptide is a dipeptide composed of 2 amino acids, which contains a peptide bond. Peptides containing 3, 4, and 5 amino acids are called three, four, and pentapeptides, respectively. The straight-bonded peptides formed by peptide bonds of 2-10 amino acids are called oligopeptides or small peptides. Recent research results show that the use of protein in the intestine of pigs is not limited to the form of free amino acids, and most of it is absorbed in the form of small peptides composed of 2 to 3 amino acids. Small peptides can pass through the intestinal mucosal cells to enter the systemic circulation. In this way, the view that peptides are completely absorbed has gradually attracted attention, and peptide research has been developed accordingly.
