Lipids are essential for storing energy, transmitting signals, and creating cellular membranes. Triglycerides, another name for fats, consist of three fatty acids attached to a glycerol. Lipids also encompass hormones and fat-soluble vitamins, making them vital for biological systems. video https://cdn.kastatic.org/ka_thumbnails_cache/78dbf842-7716-417e-97c6-f1d25d43d93a_1280_720_base.png Introduction to lipids Lipids, commonly associated with fats, are a group of biomolecules with low water solubility.

It is made up of three fatty acid chains attached to a glycerol backbone. Triglycerides can be classified as saturated (having no double bonds) or unsaturated (having double bonds). Trans fats are a type of unsaturated fat that is produced artificially and can be unhealthy to consume. video https://cdn.kastatic.org/googleusercontent/JJMxo1Fi9beh3L0FXpET_NBMZFicWpjVU8_TDPYnvB9aqnfMgC0JVrDwZVxLtY0waptE0KEjbiaZ7E77CgTZrsJF Saturated fats, unsaturated fats, and trans fats A triglyceride is a type of lipid (or fat) molecule.

Triglycerides are formed through dehydration reactions. Another word for triglyceride is triacylglycerol.
