Product Description

Product Description

Amino Acid CAS 71-00-1 L-Histidine Powder
 

Not to be confused with histamine (C5H9N3). Histidine (C6H9N3O2), abbreviated His or H, is an alpha amino acid binding imidazole functional group. It is one of the 23 most common amino acids found in proteins. Originally thought to be essential only for infants, longer-term studies have shown that it is also an essential amino acid for adults. The isoelectric point is 7.59, which is an alkaline amino acid and carries a positive charge under physiological conditions. His synthetic codons are CAU and CAC. Histidine was first isolated in 1896 by the German physician Albrecht Kossel.

Usage

L-histidine is a semi-essential amino acid, which is especially important for the growth of infants and animals. Can be used as biochemical reagent and pharmaceutical, can also be used to treat heart disease, anemia, rheumatoid arthritis and other drugs.

Function

1.L-Histidine is an essential amino acid that cannot be formed by other nutrients, and must be in the diet to be available to the body.
 
2.Most often recognized as a precursor to the allergy symptom producing hormone histamine, both histidine and histamine have essential roles in the body beyond tormenting allergy sufferers.
 
3.Histamine is well known for its role in stimulating the inflammatory response of skin and mucous membranes such as those found in the nose - this action is essential in the protection of these barriers during infection.
 
4.Histamine also stimulates the secretion of the digestive enzyme gastrin. Without adequate histamine production healthy digestion can become impaired. Without adequate L-histidine stores, the body cannot maintain adequate histamine levels.
 
5.Less well known is that L-histidine is required by the body to regulate and utilize essential trace minerals
such as copper, zinc, iron, manganese and molybdenum.
