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® Crystalline fructose is a processed sweetener derived from corn that is almost entirely fructose. D-Fructose can also be made from sucrose (table sugar) by splitting the fructose and glucose molecules. Crystalline fructose consists of at least 98% pure fructose, any remainder being water and trace minerals. Fructo-oligosaccharide(FOS),is also known as Fucto-oligo, fructose directly enters into large intestine without being digested and absorbed by human body, and in intestine it rapidly promotes reproduction of bididobactirium and other probiotics, so fructose is also called “Bifidus Factor”
