A saturated fat is a type of fat in which the fatty acid chains have all single bonds between the carbon atoms. A fat known as a glyceride is made of two kinds of smaller molecules: a short glycerol backbone and fatty acids that each contain a long linear or branched chain of carbon (C) atoms.

Saturated fatty acids have no C=C double bonds. They have the formula CH 3 (CH 2) n COOH, for different n. An important saturated fatty acid is stearic acid (n = 16), which when neutralized with sodium hydroxide is the most common form of soap. Arachidic acid, a saturated fatty acid
The terms saturated vs unsaturated are often applied to the fatty acid constituents of fats. The triglycerides (fats) that comprise tallow are derived from the saturated stearic and monounsaturated oleic acids. [3] Many vegetable oils contain fatty acids with one (monounsaturated) or more (polyunsaturated) double bonds in them.
Trimyristin is a saturated fat and the triglyceride of myristic acid with the chemical formula C 45 H 86 O 6. Trimyristin is a white to yellowish-gray solid that is insoluble in water, but soluble in ethanol , acetone , benzene , chloroform , dichloromethane , ether , and TBME .
A young adult human's fat stores average between about 15–20 kg (33–44 lb), but varies greatly depending on age, sex, and individual disposition. [10] In contrast, the human body stores only about 400 g (0.9 lb) of glycogen , of which 300 g (0.7 lb) is locked inside the skeletal muscles and is unavailable to the body as a whole.
A significant proportion of the fatty acids in the body are obtained from the diet, in the form of triglycerides of either animal or plant origin. The fatty acids in the fats obtained from land animals tend to be saturated, whereas the fatty acids in the triglycerides of fish and plants are often polyunsaturated and therefore present as oils.
However, since the fats and oils in most natural and traditionally processed foods contain both unsaturated and saturated fatty acids, [73] the complete exclusion of saturated fat is unrealistic and possibly unwise. For instance, some foods rich in saturated fat, such as coconut and palm oil, are an important source of cheap dietary calories ...
