Triglyceride vs. Lipid — What's the Difference?

A triglyceride (TG, triacylglycerol, TAG, or triacylglyceride) is an ester derived from glycerol and three fatty acids (from tri- and glyceride). Triglycerides are the main constituents of body fat in humans and other vertebrates, as well as vegetable fat.

In biology and biochemistry, a lipid is a micro biomolecule that is soluble in nonpolar solvents. Non-polar solvents are typically hydrocarbons used to dissolve other naturally occurring hydrocarbon lipid molecules that do not (or do not easily) dissolve in water, including fatty acids, waxes, sterols, fat-soluble vitamins (such as vitamins A, D, E, and K), monoglycerides, diglycerides, triglycerides, and phospholipids.

An ester formed from glycerol and three fatty acid groups. Triglycerides are the main constituents of natural fats and oils.

Any of a class of organic compounds that are fatty acids or their derivatives and are insoluble in water but soluble in organic solvents. They include many natural oils, waxes, and steroids.

Any of a class of compounds that consist of an ester of glycerol with three fatty acids and that are the chief constituents of fats and oils.

Any of a group of organic compounds, including the fats, oils, waxes, sterols, and triglycerides, that are insoluble in water but soluble in nonpolar organic solvents, are oily to the touch, and together with carbohydrates and proteins constitute the principal structural material of living cells.

(organic chemistry) A lipid, an ester of glycerol and three fatty acids (the same or different); the major constituent of animal and vegetable fats

(organic compound) Any of a group of organic compounds including the fats, oils, waxes, sterols, and triglycerides. Lipids are characterized by being insoluble in water, and account for most of the fat present in the human body.

A glyceride formed by the replacement of three hydrogen atoms in glycerin by acid radicals.

Any of a variety of oily or greasy organic compounds found as major structural components of living cells; they are insoluble in water but soluble in organic solvents such as alcohol and ether, and include the common fats, cholesterol and other steroids, phospholipids, sphingolipids, waxes, and fatty acids; some of the lipids, together with proteins and carbohydrates, form an essential structural component of living cells, as in the cell walls and membranes. The term lipid refers to its solubility in nonpolar solvents, and has no significance with regard to chemical structure.

Glyceride occurring naturally in animal and vegetable tissues; it consists of three individual fatty acids bound together in a single large molecule; an important energy source forming much of the fat stored by the body

An oily organic compound insoluble in water but soluble in organic solvents; essential structural component of living cells (along with proteins and carbohydrates)
