Product Name: S-Acetyl-L-glutathione Other Name: S-acetylglutathione Molecular Formula: C12H19N3O7S Molecular Weight: 349.36 Appearance: White powder Purity: 99% CAS NO.: 3054-47-5 EINECS No.: 221-275-5 Supplier: ZHENYIBIO S-Acetyl-L-Glutathione is a tripeptide that contains an unusual peptide linkage between the amine group of cysteine and the carboxyl group of the glutamate side-chain. S-Acetyl-L-Glutathione has strong effects of antioxidant, preventing damage to important cellular components caused by reactive oxygen species such as free radicals and peroxides.
Product Name: L-Lysyl-L-alpha-aspartyl-L-isoleucyl-N5-(aminocarbonyl)-L-ornithinamide INCI Name: TRIPEPTIDE-10 CITRULLINE Molecular Formula: C22H42N8O7 Molecular Weight: 530.62 Appearance: White powder Purity: 99% CAS Number: 960531-53-7 Standard: Enterprise Standard Supplier: ZhenYiBio Tripeptide-10 citrulline mimics decorin (decorin), regulates the formation of collagen fibers, maintains proper spatial distance and size uniformity between fibrils, enhances the stability of fibrils in tissues, and improves skin Elasticity, increase skin firmness. Decorin (decorin) is a proteoglycan related to collagen fibers mainly found in hoof tissue. It belongs to the extracellular leucine-rich small molecule proteoglycan family. It is a macromolecular sugar complex composed of a spherical nuclear protein and a glycosaminoglycan side chain containing chondroitin sulfate/dermatan sulfate.

Tocopherol is a type of vitamin E. It has E number E307. Vitamin E exists in eight different forms, four tocopherols and four tocotrienols. All feature a chromane ring, with a hydroxyl group that can donate a hydrogen atom to reduce free radicals and a hydrophobic side chain which allows for penetration into biological membranes. Compared to the others, tocopherol is preferentially absorbed and accumulated in humans. For price, specification and other details please contact us
Threonine (symbol Thr or T)[2] is an amino acid that is used in the biosynthesis of proteins. It contains an -amino group (which is in the protonated NH+ 3 form under biological conditions), a carboxyl group (which is in the deprotonated COO form under biological conditions), and a side chain containing a hydroxyl group, making it a polar, uncharged amino acid. It is essential in humans, meaning the body cannot synthesize it: it must be obtained from the diet. Threonine is synthesized from aspartate in bacteria such as E. coli.[3] It is encoded by all the codons starting AC (ACT, ACC, ACA, and ACG) For price, specification and other details please contact us.
Lysine (symbol Lys or K)[1] is an amino acid that is used in the biosynthesis of proteins. It contains an amino group (which is in the protonated NH3+ form under biological conditions), an carboxylic acid group (which is in the deprotonated COO form under biological conditions), and a side chain lysyl ((CH2)4NH2), classifying it as a basic, charged (at physiological pH), aliphatic amino acid. It is encoded by the codons, AAA and AAG. Like almost all other amino acids, the + carbon is chiral and lysine may refer to either enantiomer or a racemic mixture of both. For the purpose of this article, lysine will refer to the biologically active enantiomer L-lysine, where the -carbon is in the S configuration For price, specification and other details please contact us
