What is of L-Isoleucine with 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.
