CAS:118-52-5 Manufacturers

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.

China H&Z® Carbazochrome can reduce the permeability of capillaries, promote the shrinkage of the damaged capillary end and hemostasis.It is mainly used for hemorrhage caused by increased capillary permeability, such as idiopathic purpura, retinal hemorrhage, chronic pulmonary hemorrhage, gastrointestinal hemorrhage, epistaxis Chemicalbook, hemoptysis, hematuria, hemorrhoid hemorrhage, uterine hemorrhage, cerebral hemorrhage, etc.It is less effective for massive bleeding and arterial bleeding.Hemostatic agent, for the development of purple class disease, hereditary capillary dilatation and prevent lung, kidney, intestine, brain, uterus and other bleeding

China H&Z® Cinnamyl alcohol CAS:104-54-1 or styron is an organic compound that is found in esterified form in storax, Balsam of Peru, and cinnamon leaves. It forms a white crystalline solid when pure, or a yellow oil when even slightly impure. It can be produced by the hydrolysis of storax.

China H&Z® Saw palmetto extract is an extract of the fruit of Saw palmetto. It is rich in fatty acids and phytosterols. It has been used in traditional and alternative medicine for a variety of indications, most notably benign prostatic hyperplasia (BPH).

China H&Z® L-Serine plays an important role in the catalytic function of many enzymes. It has been shown to occur in the active sites of chymotrypsin, trypsin, and many other enzymes. The so-called nerve gases and many substances used in insecticides have been shown to act by combining with a residue of serine in the active site of acetylcholine esterase, inhibiting the enzyme completely. The enzyme acetylcholineesterase breaks down the neurotransmitter acetylcholine, which is released at nerve and muscle junctions in order to allow the muscle or organ to relax. The result of acetylcholine inhibition is that acetylcholine builds up and continues to act so that any nerve impulses are continually transmitted and muscle contractions do not stop.
