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
Examples of this function are their uses in cellular plasma and organelle membranes. Lipids have the ability to allow two layers of the membrane to develop. As a result, the cell is able to control what kinds of substances form across the walls of the cell.They are important in maintaining the structures of cells and providing a source of fuel to the body. Lipids come in the form of fatty acids, waxes, steroids and neutral fats.They can also be in compound form, which occurs when the lipids combine with another chemical compound. Under the latter category are lipolipids, glycolipids, and phospholipids. 1 person found this useful.ipids come in the form of fatty acids, waxes, steroids and neutral fats.
