9. n. A white or yellowish oily solid substance forming the chief part of the adipose tissue of animals, and also found in plants. In chemistry the fats are odorless, tasteless, colorless or white bodies, which may be either solid or liquid. They are insoluble in water and cold alcohol, but dissolve freely in ether, chloroform, and benzine. The solid neutral fats, like spermaceti, suet, and lard, and the liquid non-volatile oils, like sperm- and olive-oil, are classed together as fats. They are compound ethers formed by the union of fatty acids with the triatomic alcohol glycerin. They are composed of carbon, hydrogen, and oxygen, but contain no nitrogen. The most common and abundant are stearin, palmitin. and olein. Of these stearin and palmitin are solids at ordinary temperatures, and olein is a liquid. Most animal and vegetable fats are mixtures of two or more of the simple fats, and their hardness depends largely on the relative quantity of olein or other liquid fat in them. When a fat is treated with an alkali, the fatty acid unites with the alkaline base, making a soap, and glycerin is set free. When a soap is treated with an acid, the base is taken from the fatty acid which is thus set free.
