Sport Nutrition Medicine Raw Material Ornithine White Solid Powder For

Sport nutrition use raw material Ornithine white solid powder for bodybuilding no 70-26-8

Description:

Ornithine is a non-essential amino acid that plays a central role in the urea cycle, functioning along with Arginine and Citrulline to rid the body of ammonia, a byproduct of protein metabolism. Because Ornithine is converted into Arginine, it can help maintain healthy Arginine levels in the body. Ornithine can also be converted into other amino acids, such as citrulline, proline, and glutamate, as well as creatine, an important muscular energy source.

Specification

Apllication:

The L-Ornithine is mainly involved in the uric acid cycle, which will be very important for the excretion of ammonium nitrogen in the organism.

It will be not only used as reagent and injecta in pharmaceutical field, but also prepared for the fizzy drinks for arginine phosphokinase in food industry.

Ornithine is a non-proteinogenic amino acid that plays a role in the urea cycle. Ornithine is abnormally accumulated in the body in ornithine transcarbamylase deficiency. The radical is ornithyl.

L-Ornithine is one of the products of the action of the enzyme arginase on L-arginine, creating urea. Therefore, ornithine is a central part of the urea cycle, which allows for the disposal of excess nitrogen. Ornithine is recycled and, in a manner, is a catalyst. First, ammonia is converted into carbamoyl phosphate(H
2NC(O)OPO2−
3). Ornithine is converted into a urea derivative at the δ (terminal) nitrogen by carbamoyl phosphate synthetase. Another nitrogen is added from aspartate, producing the denitrogenated fumarate, and the resulting arginine (a guanidinium compound) is hydrolysed back to ornithine, producing urea. The nitrogens of urea come from the ammonia and aspartate, and the nitrogen in ornithine remains intact.

Ornithine is not an amino acid coded for by DNA, that is, not proteinogenic. However, in mammalian non-hepatic tissues, the main use of the urea cycle is in arginine biosynthesis, so, as an intermediate in metabolic processes, ornithine is quite important.

Ornithine, via the action of ornithine decarboxylase (E.C. 4.1.1.17), is the starting point for the synthesis of polyamines such as putrescine.

In bacteria, such as E. coli, ornithine can be synthesized from L-glutamate.

Amino acid supplements, including L-ornithine, are frequently marketed to bodybuilders and weightlifters with claims for increasing levels of human growth hormone (HGH), muscle mass and strength. A clinical study reported that L-ornithine at 2 g/d did not increase HGH. A review on the topic concluded "The use of specific amino acids to stimulate GH release by athletes is not recommended."

L-Ornithine L-aspartate (LOLA), a stable salt of ornithine and aspartic acid, has been used in the treatment of cirrhosis.
