China H&Z® Lysozyme is enzyme preparation,can be used for food and Pharmaceuticals.

China H&Z® L-Arginine Hydrochloride is one of the 20 amino acids that build up protein. L-arginine is one of the non-essential amino acids, meaning it can be synthesised in the body.L-arginine HCL is a precursor of nitric oxide and other metabolites. It is an important component of collagen, enzymes and hormones, skin and connective tissues. L-arginine plays important roles in the synthesis of various protein molecules; creatine and insulin being the most easily recognised. It may have antioxidant property and reduces accumulation of compounds such as ammonia and plasma lactate, by-products of physical exercise. It also inhibits platelet aggregation and has also been known to decrease blood pressure.

China H&Z® Glycyrrhizic acid is a flavorant and foaming agent derived from the separation of flavonoids found in the whole licorice extract from the licorice root glycyrrhiza glabra. It is 50–100 times as sweet as sugar, is soluble in water, and has a licorice taste. It has good heat stability but prolonged heating can result in some degradation. It is stable within ph 4–9; below ph 4 there could be precipitation.

Piperine is main active component of pepper.China H&Z® Black Pepper Extract is a type of alkaloid. It is found widely in nature, especially in pepper plants.We have 3% 10% 50% 95% 98% piperine, which can meet different requirements.

China H&Z® Bon/3-hydroxy-2-naphthoic Acid is light yellow powder,3-Hydroxy-2-naphthoic acid is applied in producing colour Naphthol as and other kinds intermediates of colour naphthol. Moreover, it is intermediates of medicine and organic pigment.

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.
