fat Fat, n.

1. (Physiol. Chem.)

Defn: An oily liquid or greasy substance making up the main bulk of the adipose tissue of animals, and widely distributed in the seeds of plants. See Adipose tissue, under Adipose.

Note: Animal fats are composed mainly of three distinct fats, tristearin, tripalmitin, and triolein, mixed in varying proportions. As olein is liquid at ordinary temperatures, while the other two fats are solid, it follows that the consistency or hardness of fats depends upon the relative proportion of the three individual fats. During the life of an animal, the fat is mainly in a liquid state in the fat cells, owing to the solubility of the two solid fats in the more liquid olein at the body temperature. Chemically, fats are composed of fatty acid, as stearic, palmitic, oleic, etc., united with glyceryl. In butter fat, olein and palmitin predominate, mixed with another fat characteristic of butter, butyrin. In the vegetable kingdom many other fats or glycerides are to be found, as myristin from nutmegs, a glyceride of lauric acid in the fat of the bay tree, etc.

2. The best or richest productions; the best part; as, to live on the fat of the land.

- ---excerpt from the Illustrated Bible Dictionary

Fat - (Heb. heleb) denotes the richest part of the animal, or the fattest of the flock, in the account of Abel's sacrifice (Genesis 4:4). It sometimes denotes the best of any production (Genesis 45:18; Numbers 18:12; Psalms 81:16; Psalms 147:14). The fat of sacrifices was to be burned (Leviticus 3:9; Leviticus 4:8; Leviticus 7:3; Leviticus 8:25; Numbers 18:17. Compare Exodus 29:13; Leviticus 3:3). It is used figuratively for dull, stupid. In Joel 2:24 the word is equivalent to "vat," a vessel. The Hebrew word here thus rendered is elsewhere rendered "wine-fat" and "press-fat" (Haggai 2:16; Isaiah 63:2).
