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® 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.

M,P-Cresol Cresol m/p mixture Cresylic Acid CAS:84989-04-8 M,P-Cresol/Cresol m/p mixture/Cresylic Acid

China H&Z® Tromethamine is a white crystal or powder. Tromethamin is fosfomycin intermediate, can also be used as a vulcanization accelerator, cosmetics (cream, lotion), mineral oil, paraffin emulsifier, biological buffer.

The H&Z® factory made polycaprolactone diol,which can be used as the crosslinking agent of coating material or polyurethane resin, it maintains the characteristic high flexibility of polycaprolactone while obtaining high crosslinking density.It is a new pentyl ternyl alcohol, which can improve the properties of chemical resistance and heat resistance of the resin, and meet the requirements of the gloss and durability of polyurethane coating.

Dexpanthenol is the precursor of vitamin B5, so it is also called provitamin B5.
