China H&Z® L-Pyroglutamic Acid (also known as PCA, 5-oxoproline, pidolic acid, or pyroglutamate for its basic form) is a ubiquitous but little studied natural amino acid derivative in which the free amino group of glutamic acid or glutamine cyclizes to form a lactam.It is a metabolite in the glutathione cycle that is converted to glutamate by 5-oxoprolinase. Pyroglutamate is found in many proteins including bacteriorhodopsin. N-terminal glutamic acid and glutamine residues can spontaneously cyclize to become pyroglutamate, or enzymatically converted by glutaminyl cyclases. This is one of several forms of blocked N-termini which present a problem for N-terminal sequencing using Edman chemistry, which requires a free primary amino group not present in pyroglutamic acid. The enzyme pyroglutamate aminopeptidase can restore a free N-terminus by cleaving off the pyroglutamate residue.

China H&Z® Sodium Erythorbate is White crystalline powder,Slightly salty. It is quite stable in the air in a dry state. But in solution, it will deteriorate in the presence of air, trace metals, heat and light. Melting point above 200 ℃ (decomposition). Easily soluble in water (17g / 100m1). Almost insoluble in ethanol. The pH value of the 2% aqueous solution is 5.5 to 8.0.Used as food antioxidants, anti-corrosion color additives, Cosmetic antioxidants. Sodium Erythorbate can consume oxygen in cosmetics, reduce high-valent metal ions, transfer the redox potential to the reduction range, and reduce the generation of undesirable oxidation products. Sodium Erythorbate can also be used as anticorrosive color additive.

China H&Z® Epimedium Extract can increase the blood flow of cardiovascular and cerebrovascular vessels, promote hematopoietic function, immune function and bone metabolism, and has the effects of tonifying kidney, anti-aging and anti-tumor.

China H&Z® Low-temperature Alpha-amylase is made from the strain of Bacillus subtilis through cultivation, fermentation and extraction technique. This product can be used for the liquidizing process of fruit juice,glucose, cerealose, alcohol, beer, monosodium glutamate, Shaoxing wine, distillate spirits Fermentation industry, printing and dyeing industry, as well as the desizing process of textile industry.

China H&Z® Peptidase is typically known as proteolytic enzymes. (Distinction peptidases and proteases are: protease hydrolyzed protein is a polypeptide, peptide and amino acid enzymatic hydrolysis of the proteins.) Is a peptidase enzyme capable of hydrolyzing peptide
