1前言本文简要介绍了烟酸金属络合物的制备和应用。所涉及到的烟酸金属络合物包括烟酸氯化铜,烟酸铬,烟酸锌,含铷和铜的吡啶羧酸类配合物。烟酸氯化铜络合物在治疗肌肉萎缩症,肌无力症,慢性疲劳,男性不育症等方面具有良好的效果。微量的三价铬是人体内糖,蛋白质和脂肪新陈代谢所必须的,微量元素铬缺乏会引起糖尿病。但是无机铬仅有0.5%能为人体所吸收,有机铬也仅有1-2%能被人体吸收,而烟酸铬配位络合物能直接被人体 1 Introduction This article briefly introduces the preparation and application of nicotinic acid metal complexes. The nicotinic acid metal complexes involved include copper nicotinate, chromium nicotinate, zinc nicotinate, pyridine carboxylic acid complexes containing rubidium and copper. Niacin chloride complex in the treatment of muscular dystrophy, myasthenia, chronic fatigue, male infertility and other aspects with good results. Trace amounts of trivalent chromium is the body’s sugar, protein and fat metabolism necessary, lack of trace elements of chromium can cause diabetes. However, only 0.5% of inorganic chromium can be absorbed by the human body, organic chromium is only 1-2% of the body can be absorbed, and chromium nicotinate coordination complexes can be directly to the human body
