Triarachidin (Standard) is the standard substance of Triarachidin, and it is applicable for quantitative analysis, quality control, and related research in biochemical experiments. Triarachidin (1,2,3-Trieicosanoyl Glycerol) is a triarachidic acid triglyceride. Triglycerides (TGs) are also known as triacylglycerols or triacylglycerides. TGs are the main constituent of vegetable oil and animal fats. TGs are major components of very low density lipoprotein (VLDL) and chylomicrons, play an important role in metabolism as energy sources and transporters of dietary fat. They contain more than twice the energy (9 kcal/g) of carbohydrates and proteins.
