There are four principal types: A, B, AB, and O. There are two antigens and two antibodies that are mostly responsible for the ABO types. The specific combination of these four components determines an individual's type in most cases.ndividuals with type O blood do not produce ABO antigens. Therefore, their blood normally will not be rejected when it is given to others with different ABO types. As a result, type O people are universal donors for transfusions, but they can receive only type O blood themselves.
In biology, a lipid is a substance of biological origin that is soluble in nonpolar solvents. It comprises a group of naturally occurring molecules that include fats, waxes, sterols, fat-soluble vitamins, monoglycerides, diglycerides, triglycerides, and phospholipids. The main biological functions of lipids include storing energy, signaling, and acting as structural components of cell membranes. Lipids have applications in the cosmetic and food industries as well as in nanotechnology. Scientists
Lipid Breakdown. Enzymes called pancreatic lipases break lipids in your food down into smaller pieces; you absorb these through your small intestine into your bloodstream, and cells either burn them or store them as body fat. A different type of lipase then breaks down stored body fats -- also lipids -- when your cells require more energy. Many different enzymes are involved in breaking down lipids for energy at the cellular level -- these burn lipids, producing carbon dioxide and water.
