Lipids

Lipids is a general term for a group of fat-soluble molecules that includes fats, oils, waxes, cholesterol, sterols, fat-soluble vitamins (such as vitamins A, D, E and K), monoglycerides, diglycerides, phospholipids, etc. Lipids perform the functions of energy storage, building cell membranes, and acting as signaling molecules. Although some lipids are an absolute necessity for life there are some such as cholesterol, which when present in high levels, can lead to health conditions.

Cholesterol and Obesity

Cholesterol is a lipid, or type of fat produced by the liver and derived from various dietary sources. Although often referred to in negative terms, cholesterol plays an essential part in many processes within the body, including formation of cell membranes and nerve linings and in the manufacture of bile acids, fat-soluble vitamins and certain hormones. However, high cholesterol or hypercholesterolemia is strongly associated with significant health issues including heart disease and stroke.
