Our body is made out of four basic classes of organic compounds: carbohydrates, lipids, proteins, and nucleic acids. Each class performs a unique role and is vital for the function of life.
Organic Compound: A chemical substance created within an organism.
Carbohydrate: An organic compound containing carbon, hydrogen, and oxygen that supply the energy living systems need to survive.
Lipid: An organic compound produced for storing energy.
Protein: An organic compound making up muscles, enzymes, and other organs in the body.
Nucleic Acid: An organic compound used to store genetic information.
Fatty Acid: Molecule in which carbon atoms are bonded to hydrogen atoms or other groups of atoms.
Amino Acid: Small molecule that is a building block of proteins.
Nucleotide: Small molecule containing a sugar, phosphate group, and base that is a building block of nucleic acids.
Complementary Base Pair: Pair of nucleotide bases that bond together.
There are four main types of organic compound responsible for cellular functions within cells. These are carbohydrates, lipids, proteins, and nucleic acids.
