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”

China H&Z® Calcium acetate in the food industry has served as a mold suppression agent stabilizer, buffer and increasing the use of scent, which itself has calcium, which also can be used for medicine, chemical reagents.

Sodium propanoate or H&Z® sodium propionate from China is the sodium salt of propionic acid which has the chemical formula Na(C2H5COO). It is used as a food preservative and is represented by the food labeling E number E281 in Europe; it i

Sodium ascorbate of China H&Z® supplier is sodium slat of ascorbic acid, which is commonly called vitamin C. It is slightly yellow to white powder, odorless, soluble in water. The molecular formula of sodium vitamin C is C6H7NaO6, and its CAS number is 134-03-2. In 1,000 grams sodium ascorbate, it contains 889g ascorbic acid and 111g sodium.

China H&Z® Xylitol is a naturally-occurring 5-carbon polyol sweetener. It is found in fruits and vegetables, and is even produced by the human body itself. It can absorb heat when dissolved in water, with moisture absorbing function, and transient diarrhea can be induced when excessively taken. The product can also treat constipation.
