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® Dimethyl sulfoxide (DMSO) is an organosulfur compound with the formula (CH3)2SO. This colorless liquid is an important polar aprotic solvent that dissolves both polar and nonpolar compounds and is miscible in a wide range of organic solvents as well as water. It has a relatively high melting point. DMSO has the unusual property that many individuals perceive a garlic-like taste in the mouth after contact with the skin.

China H&Z® Neosperidin Dihydrochalcone (NHDC) is a new sweetener which is extracted from natural citrus plants and hydrogenated. It has the characteristics of high sweetness, good taste, lasting aftertaste, low calorie, non toxicity and good stability. It is the most attractive new sweetener and bitterness shielding agent, which is widely used in food industry and feed industry.

China H&Z® Konjac Gum is a kind of pure natural hydrocolloids, Konjac Gum main ingredients is Konjac Glucommanan(KGM)with high purity of more than 85% on dry basis. White in color, fine in particle size, high viscosity and with no special smell of konjac, stable when dissolved in the water.Konjac Gum has the strongest viscosity among the plant -based water -soluble gelling agent. Fine particle size, fast solubility, high expand capability of 100 times of its weight, stable and nearly odorless.

China H&Z® Thymol is part of a naturally occurring class of compounds known as biocides, with strong antimicrobial attributes when used alone or with other biocides such as carvacrol. In addition, naturally-occurring biocidal agents such as thymol can reduce bacterial resistance to common drugs such as penicillin.
