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.

H&Z® from China Dicyclanil is a growth regulator disturbing the form of insect epiderimis..Have strong adhesive force and have good sustaining effect on epizootic helminthes.for use in the prevention and cure effectively of pest such as cotton bollworm,stinkbug,tobacco aphid noctuid,rice louse,cucumber cestode, godwit cicada of cotton,corn,vegetable etc.And effectively prevent from housefly and stegomyia.

China H&Z® L-Malic acid , as an acidulant, is especially suitable for jelly and foodstuff containing fruit ingredient. It can keep the natural color of juice. Used in health drinks, it can resist fatigue and protect liver, kidney and heart.

China H&Z® Subtilisin Protease (also named alcalase protease) is a protein enzyme, it comes from Bacillus licheniformis after its fermentation and refinement, it mainly composed by Bacillus licheniformis protease, the molecular weight is approximately 27300. It’s a endoprotease of serine, can hydrolysis the macro-molecule protein into free amino acid etc.

China H&Z® ZincG lycinate is a high-tech product with the main ingredient of zinc glycinate chelate, which can be directly absorbed and utilized by human body. Compared with the secondary generation of food enrichment, such as zinc lactate and zinc gluconate, zinc glycinate chelate overcomes the disadvantage of low bioavailability.

China H&Z® Methyl Paraben, white crystalline powder or colorless crystal, soluble in alcohol, ether and acetone, very slightly soluble in water, boiling point 270-280 °C. It is mainly used as a bactericidal preservative for organic synthesis, food, cosmetics and medicine, and also as a preservative for feed.
