Fats, like other lipids, are generally hydrophobic, and are soluble in organic solvents and insoluble in water. Fat is an important foodstuff for many forms of life, and fats serve both structural and metabolic functions. They are a necessary part of the diet of most heterotrophs (including humans).
A saturated fat is a type of fat in which the fatty acids all have single bonds. A fat is made of two kinds of smaller molecules: monoglyceride and fatty acids. Fats are made of long chains of carbon (C) atoms. Some carbon atoms are linked by single bonds (-C-C-) and others are linked by double bonds (-C=C-).
