中碳链甘油三酸酯(MCT)是中性脂肪的一种,是含有C_6～C_(12)脂肪酸的甘油酯。含有C_(12)以上的称为长碳链甘油三酸酯(LCT),含有C_5以下的称为短碳链甘油三酸酯(SCT)。MCT存在于多种天然油中,但以椰子油中的含量为最丰富,约占总脂肪酸量的10～15%;其次为乳脂,约含5～10%。早年一些研究者将椰子油水解、蒸馏、分离出游离脂肪酸,然后将其中的中碳链脂肪酸(MCPA)酯化,得到一种MCT。以后对此新的油脂进行了一系列研究,证明此种MCT可作为燃料以供给机体热能,但很少在体内积存为体脂,并具有降体重,降血脂的效果,因此在最近20余年内,已被广泛用于医药和临床,成为众所瞩目的新科研领域。MCT除上述的由天然食品(如椰子油)中提取外,德国纳粹在第二次世界大战期间,由于战争带来的食用油缺乏,曾用石油付产品或褐煤制得各种合成油,
Medium-chain triglyceride (MCT) is a kind of neutral fat, glycerol esters containing C_6 ~ C_ (12) fatty acids. The long-chain triglyceride (LCT) containing C_ (12) or more and the short-chain triglyceride (SCT) containing C_5 or less are contained. MCT is found in many natural oils, but is most abundant in coconut oil, accounting for 10-15% of total fatty acids; followed by milk fat, containing about 5-10%. In the early years, some researchers hydrolyzed and distilled coconut oil to separate free fatty acids and then esterified the middle chain fatty acid (MCPA) to obtain MCT. After a series of studies on this new fat, proved that this kind of MCT can be used as fuel to supply body heat energy, but seldom accumulated in the body as body fat, and has the effect of lowering body weight and lowering blood fat. Therefore, in the recent 20 years , Has been widely used in medicine and clinical, has become the focus of new research areas. In addition to the above MCT extracted from natural foods (such as coconut oil), the German Nazi during the Second World War, due to the lack of edible oil caused by the war, have been made with petroleum-based products or lignite produced a variety of synthetic oil,
