Lipids are organic compounds of different chemical
structure, including fats and oils, waxes, phospholipids and steroids. Their
common feature is insolubility in water, and extremely good solubility in
organic solvents. The basic structure of most lipids is the triglyceride. Triglycerides
provide a key calorie source for the body and are the major form of fat in
foods.
The
three main roles of lipids are:
- energy Storage
- construction of biological membranes
- transmission of signals between cells
Types
of lipids are saturated fats and unsaturated fats.
Almost
all foods contain a variety of saturated and unsaturated fatty acids. Saturated
fat should be limited in our diet because it can raise blood cholesterol.
