Oil vs. Lipid — What's the Difference?

An oil is any nonpolar chemical substance that is a viscous liquid at ambient temperatures and is both hydrophobic (does not mix with water, literally "water fearing") and lipophilic (mixes with other oils, literally "fat loving"). Oils have a high carbon and hydrogen content and are usually flammable and surface active.

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.

A viscous liquid derived from petroleum, especially for use as a fuel or lubricant.

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.

Oil paint

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.

Information or facts

(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.

Lubricate, coat, or impregnate with oil

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.

Supply with oil as fuel

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

Any of numerous mineral, vegetable, or synthetic substances or animal or vegetable fats that are generally slippery, combustible, viscous, liquid or liquefiable at room temperatures, soluble in various organic solvents such as ether but not in water, and used in a great variety of products, especially lubricants and fuels.

Petroleum.

A petroleum derivative, such as a machine oil or lubricant.

A protective or cosmetic liquid applied to the skin or hair.

Oil paint.

A painting done in oil paint.

To lubricate, supply, cover, or polish with oil.

Liquid fat.

Petroleum-based liquid used as fuel or lubricant.

Petroleum

(countable) An oil painting.

(painting) Oil paint.

(attributive) Containing oil, conveying oil; intended for or capable of containing oil.

(transitive) To lubricate with oil.

(transitive) To grease with oil for cooking.

Any one of a great variety of unctuous combustible substances, more viscous than and not miscible with water; as, olive oil, whale oil, rock oil, etc. They are of animal, vegetable, or mineral origin and of varied composition, and they are variously used for food, for solvents, for anointing, lubrication, illumination, etc. By extension, any substance of an oily consistency; as, oil of vitriol.

To smear or rub over with oil; to lubricate with oil; to anoint with oil.

A slippery or viscous liquid or liquefiable substance not miscible with water
