BIOL 1001 Chapter : Chapter 3 Biological Molecules
Document Summary
Biological molecules are abundant in living organisms and are essential for life. There are 4 types of biological molecules: carbohydrates, lipids (fats), proteins, and nucleic acids. Aside from water, most biologically related molecules contain carbon. --organic molecules are molecules containing carbon and hydrogen. Living organism can synthesize and use this type of molecule. These have c (but not h) and are not organic molecules (inorganic): Life is dynamic: as molecules within cells interact, they change (chemically and structurally). These changes give cells the ability to obtain and use nutrients, get rid of waste, move, grow, and reproduce: as you"ll see, these molecules have certain properties that allow for the different interactions. Carbon monoxide: only living organisms can create organic molecules, carbon atoms are the most versatile building blocks of molecules. Carbon is the key to the great variety of organic molecules that make life on earth possible.
