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.

Thiamine Hydrochloride made by China H&Z® factory, Thiamine or Vitamin B1 is a water-soluble vitamin of the B complex,Thiamine is used in the biosynthesis of the neurotransmitter acetylcholine and gamma-aminobutyric acid (GABA). In yeast, TPP is also required in the first step of alcoholic fermentation.

H&Z® Ferrous Gluconate Dihydrate, molecular formula C12H22O14Fe·2H2O, relative molecular mass of 482.18.In food can be used as a colorant, nutrient fortifier, can be from reduced iron and gluconic acid.Ferrous gluconate is characterized by high bioavailability, good solubility in water, mild and astringent flavor, and more strengthening in milk drinks, but it is also easy to cause changes in food color and flavor, which limits its application to some extent.

China H&Z® Taurine is widely found in the tissues and cells of mammals, birds, fish and aquatic invertebrates. Some studies have found that taurine not only has good food-inducing effect, but also can improve the activity of various digestive enzymes in the body. In addition, taurine can also promote animal growth and regulate osmotic pressure. As a feed additive, it has been widely used in the aquaculture industry

China H&Z® Ethyl paraben is white crystalline substance with a slightly bitter taste and burning numbness.As an antibacterial preservative, ethylparaben is widely used in cosmetics, food and pharmaceutical preparations.It can be used alone or in combination with other parabens or antibacterial agents.It is one of the most frequently used antibacterial preservatives in cosmetics.These parabens can play a role in a wide pH range, and have spectral antibacterial activity, of which the most effective for yeast and mold.Because the solubility of paraben is poor, its salts are often used.

Curcumin can color food, feed and pharm,all-natural food coloring agent.
