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® Crystal Violet Lactone is an important functional dye in the production of pressure-sensitive materials or heat sensitive materials.

China H&Z® Esculin is a glycosidecomposed of glucose and a dihydroxycoumarin compound. Esculin is a product of a coumarin derivative extracted from the bark of flowering ash (Fraxinus ornus).

China H&Z® Berberine hydrochlorideis a kind of isoquinoline alkaloids, extracted from the rhizome of Coptis Chinensis (also called Chinese Goldthread).

Rhodioloside is a glycoside compound found in the plant Rhodiola rosea. It is thought to be one of the compounds responsible for the antidepressant and anxiolytic actions of this plant, along with rosavin. Salidroside may be more active than rosavin, even though many commercially marketed H&Z® Rhodiola rosea extracts are standardised for rosavin content rather than salidroside.
