用途：营养增补剂 Nutrition Enchancer.
L-异亮氨酸为人体必须氨基酸之一，每天最低需要量约0.7g，但过量食用将与亮氨酸产生拮抗作用，有碍发育。本品可强化各种食品，如小麦粉、麦谷蛋白、花生粉、马铃薯等所含异亮氨酸为限制氨基酸，宜于强化，该品还与其他必需氨基酸共用于氨基酸制备及氨基酸输液。该品也用于生化研究、细菌学及组织培养。
L-isoleucine is one of essential Amino Acid for human body, one person need at least 0.7g every day. This product can be used as nutrition enhancer, strengthening the nutrition of many foods, such as wheat, peanut powder, sweet potato and so on. It is can be mixed with other amino acids for amino infusion, and for bio-chemistry study and bacteriology and tissue culturing.
