an organic molecule consisting only of carbon and hydrogen
Isomers
one of several compounds with the same molecular formula but different structures and therefore different properties; the three types of isomers are structural isomers, cis-trans isomers, and enantiomers
Structural Isomers
one of several compounds that have the same molecular formula, but differ in the covalent arrangement of their atoms
Cis-trans Isomers
one of several compounds that have the same molecular formula and covalent bonds between atoms but differ in the spatial arrangements of their atoms owing to the inflexibility of double bounds, formerly called a geometric isomer
Enantiomers
one of two compounds that are mirror images of each other and that differ in shape due to the presence of asymmetric carbon
Functional Groups
a specific configuration of atoms commonly attached to the carbon skeletons of organic molecules and involved in chemical reactions
Adenosine Triphosphate (ATP)
an adenine-containing nucleoside triphosphate that releases free energy when its phosphate bonds are hydrolyzed; this energy is used to drive endergonic reactants in cells
