Product Description


L-Isoleucine CAS#73-32-5

Crystalline leaflets or a white, crystalline powder having a bitter taste. It is soluble in 25 parts of water, slightly soluble in hot alcohol, and soluble in diluted mineral acids and in alkaline solutions. It sublimes at between 168°C and 170°C, and melts with decomposition at about 284°C. The pH of a 1 in 100 solution is between 5.5 and 7.0.

Absolute: The absolute is prepared by alcoholic extraction of the concrete in approximately 55 to 60% yields. The absolute consists of a semisolid, olive-green mass with a characteristic ambergris odor.

Product Usage

L-Isoleucine, also known as Isoleucine, is an amino acid that is an isomer of leucine. It is important in hemoglobin synthesis and regulation of blood sugar and energy levels. L-Isoleucine is one of the essential amino acids that cannot be made by the body and is known for its ability to help endurance and assist in the repair and rebuilding of muscle. This amino acid is important to body builders as it helps boost energy and helps the body recover from training.
