Lipids are a broad group of organic compounds that include fats, waxes, sterols, fat-soluble vitamins (such as vitamins A, D, E and K), monoglycerides, diglycerides, phospholipids, and others.
Lipid, any of a diverse group of organic compounds including fats, oils, hormones, and certain components of membranes that are grouped together because they do not interact appreciably with water.
Lipids are fatty, waxy, or oily compounds that serve as the building blocks of all living cells. Three main types of lipids (phospholipids, triglycerides, and sterols like cholesterol) are essential to help regulate hormones, transmit nerve impulses, and store energy as fat.
Cholesterol is a lipid in your blood. Your body needs it to help you take in fats and vitamins and make hormones. Cholesterol and triglycerides avoid water, so they can’t travel through blood themselves. This is why they combine with proteins to make lipoproteins that can move throughout your body.
Lipids are a group of diverse macromolecules consisting of fatty acids and their derivatives that are insoluble in water but soluble in organic solvents. Lipids consist of fats, oils, hormones, and certain components of membranes that are grouped together because of their hydrophobic interactions.
Lipids are essential constituents of cellular membranes. Once regarded merely as structural components, lipids have taken centre stage with the discovery of their roles in cell signalling and in the generation of bioactive metabolites.
The broad definition of a lipid, i.e., any substance that is insoluble in water but soluble in non-aqueous solvents, encompasses a multitude of molecules that are further characterized under an extensive range of lipid classes.
