Factory Provide Amino Acid Nutritional Supplement L Leucine Powder CAS 61-90-5 L-Leucine
Introduction
L-leucine (L-Leucine), also known as leucine, namely α-amino-γ-methylvaleric acid, α-amino-isocaproic acid, molecular formula C6H13O2N. In 1819 Proust first isolated it from cheese, and later Braconnot crystallized it from acid hydrolysates of muscle and wool and named it leucine.
L-leucine is one of the eight amino acids necessary for human body. It belongs to the fatty family of amino acids in 20 protein amino acids. It is called three branched amino acids together with L-isoleucine and L-valine. And D- leucine is an enantiomer, at room temperature white glossy hexahedral crystals or white crystalline powder. Odorless, slightly bitter. In the presence of hydrocarbons, the property is stable in inorganic acid aqueous solution. Dissolves in 40ml water and about 100ml acetic acid per gram. Very slightly soluble in ethanol or ether, soluble in formic acid, dilute hydrochloric acid, alkaline hydroxide and carbonate solutions.
Leucine can be used as a nutritional supplement and flavoring agent. The best sources of leucine include brown rice, beans, meat, nuts, soy meal, and whole grains. Since it is an essential amino acid, this means the body cannot produce it on its own, only through the diet. People engaged in high levels of physical activity and low protein diets should consider taking a white acid supplement. Although independent supplements are available, they are best taken with isoleucine and valine. Therefore, it is more convenient to choose a combination supplement.

Application L-leucine
1.It is the forth most concentrated amino acid in skeletal muscle tissue - it comprises about eight percent of the total amino acid count in your body's protein structures.
2. As one of the three BCAA's, L-Leucine is essential to your basic health. It has both athletic and medical applications.
3.L-Leucine maintains nitrogen balance, and it has also been shown to enhance thinking abilities that can decline as physical activity becomes more intense
4. L-Leucine also works to heal bone, skin and muscle tissue.
