Organic Chemistry
| Question | Answer |
|---|---|
| organic chemistry | The study of carbon compounds (organic compounds) |
| hydrocarbon | An organic molecule consisting only of carbon and hydrogen |
| isomer | One of several organic compounds with the same molecular formula but different structures and therefore different properties. The three types of isomers are structural isomers, geometric isomers, and enantiomers |
| structural isomer | One of several organic compounds that have the same molecular formula but differ in the covalent arrangments of their aoms |
| geometric isomer | One of several organic compounds that have the same molecular formula but differ in the spatial arrangements of their atoms |
| enantiomer | One of two molecules that are mirror images of each other |
| functional group | A specific configration of atoms commonly attched to the carbon skeletons of organic molecules and usually 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 reactions in cells |
| hydoxyl group | A functional group consisting of a hydrogen atom joined to an oxygen atom by a polar covalent bond. Molecules possessing this group are soluble in water and are called alcohols |
| carbonyl group | A functional group present in aldehydes and ketones and consisting of a carbon atom double-bonded to an oxygen atom and also bonded to a hydoxyl group |
| carboxyl group | A functional group present in organic acids and consisting of a single carbon atm double-bonded to an oxygen atom and also bonded to a hydroxyl group |
| amino group | A functional group that consists of a nitrogen atom bonded to two hydrogen atoms; can act as a base in a solution, accpeting a hydrogen ion and acquiring a charge of 1+ |
| sulfhydryl group | A functional group consisting of a sulfur atom bonded to a hydrogen atom (-SH) |
| phosphate group | A functional group important in energy transfer |
