Organic Compounds
Proteins
Nucleic Acids
Lipids
Carbohydrates
Used as a main source of energy. Examples are starches and sugars.
Used to store energy. Examples are oils, fats and waxes.
Stores and transmits hereditary, or genetic, information. Examples are DNA and RNA.
Can control the rate of reactions and cell processes, are used to form bones and muscles, and transport substances into or out of cells or help to fight disease.
Chemical Reactions
In chemical reactions, chemical bonds are broken and built. Sometimes, energy is needed to make it react, and sometimes no energy is needed.
One chemical changes into another. Process involves reactants, which originally enter reaction, and products, which are the result.
Enzymes
Enzymes act a a biological catalyst. Naturally speeds up reactions. Reactants that act with enzymes are called substrates.
