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).
The most common type of fat is called a triglyceride, or triacylglycerol, which contains 3 fatty acids attached to the backbone and resembles a fork without the handle. Because there are many different fatty acids that can be attached to the backbone, there are many different types of triglycerides or fats.
