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
Lipids Examples. Lipids are the fatty or waxy molecules that make up the basic structure of many cells in both plants and animals. They go by other terms depending on where they are found, including triacylglycerol, triglyceride, and glycerolipid, just to name a few. Lipids serve important functions in the cell. First, they form a support structure for the cellular and nuclear membranes. They also perform a role in the signaling and transport processes of the cell, especially those involving fat-soluble nutrients like vitamins A, E, and K. Finally, lipids are an important way for cells to store energy. While many people use the terms lipids and fats synonymously, fats are actually just a subgroup of lipids, as there are other kinds.
