摘要
肌酸(creatine,Cr)又称为N-甲基胍乙酸或肌肉素,是一种含氮有机酸。已广泛应用于改善人类健康,尤其用于促进肌肉生长。本文综述了肌酸在动物体内的合成、转运和储存规律,以及肌酸在肌肉和肝脏能量代谢中的作用,分析了饲料补充肌酸对动物生长和屠宰性能的影响,并从肌肉pH、系水力和肉色角度综述了肌酸对肉品质影响的研究进展,最后对肌酸在水产动物中的应用前景进行了展望,以期为肌酸在水产动物营养中的研究和在饲料中的应用提供参考。
Creatine (Cr) is an amino acid derivative, also known as N-methylphthalic acid or musclin. It has been widely used to improve human health, especially for promoting muscle growth. This paper reviewed the synthesis, transport and storage of creatine in animals, and the role of creatine in energy metabolism in muscle and liver. We analyzed the effects of dietary creatine supplementation on animal growth and slaughter performance, and reviewed the studies for the effects of dietary creatine on meat quality, including muscle pH, water holding capacity and flesh color. Finally, the prospects of further research on application of creatine in aquatic animals were discussed.
