用途：營養(yǎng)增補劑 Nutrition Enchancer.
L-異亮氨酸為人體必須氨基酸之一，每天最低需要量約0.7g，但過量食用將與亮氨酸產(chǎn)生拮抗作用，有礙發(fā)育。本品可強化各種食品，如小麥粉、麥谷蛋白、花生粉、馬鈴薯等所含異亮氨酸為限制氨基酸，宜于強化，該品還與其他必需氨基酸共用于氨基酸制備及氨基酸輸液。該品也用于生化研究、細菌學(xué)及組織培養(yǎng)。
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.
