Analysis of Triglycerides Using the Nexera™ UC Supercritical Fluid Chromatograph

Triglycerides are a kind of neutral lipids that are stored in adipose tissue in the bodies of animals, and are broken down to supply energy to cells when they need it. They are known to be the main component of vegetable oils etc., which are included in a lot of food. Triglycerides are constituted of glycerol (glycerin) bonded to three fatty acids (acyl groups) (Fig. 1) and are highly hydrophobic; there are very many molecular species depending on the composition of the acyl groups and their bonding positions. In vegetable oils, the types of acyl groups that constitute the triglycerides differ depending on the ingredients. Here, we introduce examples of the analysis of triglycerides using supercritical fluid chromatography (SFC). H. Terada, T. Hattori
