The term "chain triglyceride" refers to a type of fat found in foods that is composed of three fatty acids connected together with a glycerol molecule. Triglycerides are the primary form of dietary fat and provide energy for the body, as well as play important roles in cell membrane structure and hormone production. The length and composition of the fatty acid chains can vary between different types of triglycerides, which affects their melting point, taste, and nutritional value.
