15297117164organic chemistryThe study of carbon & hydrogen compounds (organic compounds).0
15297117176tetravalent4 electrons in valence shell, Ex. carbon1
15297117165hydrocarbonAn organic molecule consisting only of carbon and hydrogen.2
15297117166isomerOne of several compounds with the same molecular formula but different structures and therefore different properties. The three types are structural, geometric, and enantiomers.3
15297117167structural isomerOne or several compounds that have the same molecular formula but differ in the covalent arrangement of their atoms. (DIFFERENT SHAPE)4
15297117168geometric isomerOne 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 bonds (DIFFERENT ARRANGEMENT)5
15297117169enantiomerOne or two compounds that are mirror images of each other and that differ in shape due to the presence of an asymmetric carbon. (MIRROR IMAGE)6
15297117170estradiolA steroid hormone that stimulates the development and maintenance of the female reproductive system and secondary sex characteristics; the major estrogen in mammals.7
15297117171testosteroneAsteroid hormone required for development of the male reproductive system, spermatogenesis, and male secondary sex characteristics; the major androgen in mammals.8
15297117172functional groupsA specific configuration of atoms commonly attached to the carbon skeletons of organic molecules and involved in chemical reactions.9
15297117173hydroxyl group-OH polar ex: alcohol10
15297117174carbonyl groupC=O ketone and aldehyde11
15297117177carboxyl group(O=C=OH) amino acids12
