[ Function and Usage ]
It is one of 8 kinds essential amino acid for human body.
It is essential for the growth of adults, babies and children.
The lack of L-isoleucine may cause skeletology atrophy and
denaturizing. It has especially wide application in the field
of pharmaceutical and food industry.
