Term | Definition |
organic compound | a covalently bonded compound that contains carbon, excluding carbs and oxides. |
functional group | the portion of a molecule that is active in a chemical reaction and that determines the properties of many organic compounds. |
monomer | a simple molecule that can combine with other like or unlike molecules to make a polymer. |
polymer | a large molecule that is formed by more than five monomers, or small units. |
macromolecule | a very large organic molecule, usually a polymer, composed of hundreds or thousands of atoms. |
condensation reaction | a chemical reaction in which two or more molecules combine to produce water or another simple molecule. |
hydrolysis | a chemical reaction between water and another substance to form two or more new substances; a reaction between water and a salt to create an acid or base. |
adenosine triphosphate | an organic molecule that acts as the main energy source for cell processes; composed of a nitrogenous base, a sugar, and three phosphate groups. |
carbohydrate | organic compounds composed of carbon |
monosaccharide | a monomer of a carb |
polysaccharide | one of the carbs made up of long chains of simple sugars |
protein | an organic compound that is made of one or more chains of amino acids and that is a principal component of all cells. |
amino acid | an organic molecule that contains a carboxyl and an amino group and that makes up proteins; a protein monomer. |
peptide bond | the chemical bond that forms between the carboxyl group of one amino acid and the amino group of another amino acid. |
polypeptide | a long chain of several amino acids |

wax | a type of structural lipid consisting of a long fatty-acid chain that is joined to a long alcohol chain. |
steroid | a type of lipid that consists of four carbon rings to which various functional groups are attached and that usually has a physiological action |
nucleic acid | an organic compound, either RNA or DNA, whose molecules are made up of one or two chains of nucleotides and carry genetic information. |
deoxyribonucleic acid | the material that contains the information that determines inherited characteristics |
ribonucleic acid | a natural polymer that is present in all living cells and that plays a role in protein synthesis |
nucleotide | in a nucleic-acid chain, a subunit that consists of a sugar, a phosphate, and a nitrogenous base. |
