Medium Chain Triglycerides (MCT) are Triglycerides whose fay acids have an aliphac tail of 6-12 carbon atoms. The fay acids found in MCT's are called Medium Chain Fay Acids (MCFA's). Like all Triglycerides MCT's are composed of a glycerol backbone and three fay acids. In case of MCT's, 2 or 3 of the fay acid chains aached to glycerol are of medium length.
