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
Micelles in the body allows for the absorption of molecules that are insoluble in water such as lipids. They also carry lipid soluble vitamins to the small intestine. Micelles usually form in detergents as their primary function is to absorb these lipids by inserting long hydrophobic tails from the soap into the lipids/fats, while the hydrophilic heads face the non polar molecules allowing for the emulsion of the lipids.
