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
Carbohydrates: Carbohydrates are organic compounds made of  carbon, hydrogen, and oxygen atoms. Carbs are made of  monosacharrides (single sugars) linked together. Thei â¦ r function is  to provide a key source of energy for cells. An example is starch,  made of many linked glucose molecules.   2. Lipids: Lipids are nonpolar molecules that are not soluble in  water. They include fats, phospholipids, steroids, and waxes.  Lipids' functions are to provide energy and serve an important part  in the structure and functioning of cell membranes.  4. Nucleic acids: Nucleic acids are long chains of smaller  molecules called nucleotides. Nucleic acids mainly serve the  purpose of providing the organism with its genetic blueprint and  coding. They basically tell you who you are.DNA and RNA are two  types of nucleic acids.
