| amino group | functional group that consists of a nitrogen atom bonded to two hydrogen atoms |
| carbonyl group | functional group present in aldehydes and ketones and consisting of a carbon atom double-bonded to an oxygen atom |
| carboxyl group | functional group present in organic acids and consisting of a single carbon atom double-bonded to an oxygen atom and also bonded to a hydroxyl group |
| enantiomer | One of two molecules that are mirror images of each other |
| functional group | atoms commonly attached to the carbon skeletons of organic molecules and usually involved in chemical reactions |
| geometric isomer | organic compounds that have the same molecular formula but differ in the spatial arrangements of their atoms |
| hydrocarbon | organic molecule consisting only of carbon and hydrogen |
| hydroxyl group | unctional group consisting of a hydrogen atom joined to an oxygen atom by a polar covalent bond |
| isomer | organic compounds with the same molecular formula but different structures and therefore different properties |
| organic chemistry | study of carbon compounds |
| phosphate group | functional group important in energy transfer |
| structural isomer | organic compounds that have the same molecular formula but differ in the covalent arrangements of their atoms |
| sulfhydryl group | unctional group consisting of a sulfur atom bonded to a hydrogen atom (--SH) |
| trans | two noncarbon atoms are on opposite sides relative to the double bond |
| cis | two noncarbon atoms are on the same side relative to the double bond |
| alcohol | water soluble molecule with a hydroxyl group |
