China H&Z® Astaxanthin is a precious raw material for health,can be used enhance immunity, anti-oxidation, anti-inflammatory, eye and brain health, regulate blood lipid and other aspects of natural, healthy products.

China H&Z® Papain is to use biological engineering plants from papaya immature fruit extract of biological products and natural, it is is composed of 212 amino acids.

China H&Z® Cholesterol, also known as cholesterol, a cyclopentane polyhydrophenanthrene derivative, is an important component of various membrane phase structure of human cells and nerve myelin sheath.

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® Diosmin is also called Alvenor. It is a kind of drug for the treatment of hemorrhoid symptoms related to acute episodes, can also be used in the treatment of symptoms associated with venous lymphatic insufficiency (leg heavy, pain, morning acid swells discomfort).Diosmin hesperidin is a plant chemical that is classified as a "bioflavonoid". It is found primarily in citrus fruits. People use it asmedicine.Hesperidin alone, or in combination with other citrus bioflavonoids (diosmin, for example), is most often used for bloodvessel conditions such as hemorrhoids,varicose veins, and poor circulation (venous stasis). It is also used to treat lymphedema, a condition involving fluid retention that can be a complication of breast cancer surgery.

Freely soluble in formic acid, very slightlysoluble in water,practically insoluble in ethanol and in . Dissolve in dilute hydrochloric acid and in dilute nitric acid. Aside from being a proteinogenic amino acid, tyrosine has a special role by virtue of the phenol functionality. It occurs in proteins that are part of signal transduction processes. L-tyrosine functions as a receiver of phosphate groups that are transferred by way of protein kinases (so-called receptor tyrosine kinases). Phosphorylation of the hydroxyl group changes the activity of the target protein.China H&Z® L-tyrosine is a precursor to neurotransmitters and increasesplasma neurotransmitter levels (particularly and )but has little if any effect on mood.The effect on mood is more noticeable in humans subjected to stressful conditions.
