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.

L-Hydroxyproline from China H&Z® is a nonessential amino acid, which means that it is manufactured from other amino acids in the liver; it does not have to be obtained directly through the diet.Hydroxyproline is necessary for the construction of the body's major structural protein, collagen. Defects in carcinoma synthesis lead to easy bruising, physical bleeding, breakdown of connective tissue of the ligaments and tendons, and increased risk to blood vessel damage. Increased spill of hydroxyproline in The urine is generally associated with breakdown of connective tissue due to disease process and may also be a manifestation of vitamin C deficiency.

Bacillus Subtilis as feed additive is a kind of green environmental product.

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.
