Compound Ginkgo Biloba Extract Capsules Manufacturers

China H&Z® L-Ribose is a very important saccharide concered with life and heredity, which plays a very important role in physiology. L-Ribose has effective anticancer ability and little side-effect on normal cell.

China H&Z® Ferulic acid powder is extracted from the Rice bran,Ferulic acid is white powder,the melting point is 174 °C, ferulic soluble in hot water, ethanol and ethyl acetate, slightly soluble in ether, insoluble in benzene and petroleum ether.

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.

Replacement of Antimony Oxide Antimony-free Synergistic Flame Retardant for PVC

China H&Z® Clindamycin phosphate is a water-soluble ester of the semisynthetic antibiotic produced by a 7 (S)-chloro-substitution of the 7 (R)-hydroxyl group of the parent antibiotic, lincomycin. It is a derivative of lincomycin(a lincosamide). It has primarily bacteriostatic action against Gram-positive aerobes and a wide range of anaerobicbacteria. Doses are expressed in terms of the base: Clindamycin 1g-1.2g clindamycin phosphate.
