Terms : Hide Images
7300446751organic chemistryThe study of carbon & hydrogen compounds (organic compounds).0
7300446752carbonthis atom has 4 electrons in valence shell and can form 4 covalent bonds with other atoms1
7300446753hydrocarbonAn organic molecule consisting only of carbon and hydrogen.2
7300446754isomerOne of several compounds with the same molecular formula but different structures and therefore different properties. The three types are structural, geometric, and enantiomers.3
7300446755structural isomerOne or several compounds that have the same molecular formula but differ in the covalent arrangement of their atoms. (DIFFERENT SHAPE)4
7300446756geometric 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
7300446757enantiomerOne 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
7300446758estradiolA steroid hormone that stimulates the development and maintenance of the female reproductive system and secondary sex characteristics; the major estrogen in mammals.7
7300446759testosteroneAsteroid hormone required for development of the male reproductive system, spermatogenesis, and male secondary sex characteristics; the major androgen in mammals.8
7300446760functional groupsA specific configuration of atoms commonly attached to the carbon skeletons of organic molecules and involved in chemical reactions.9
7300446761hydroxyl groupA chemical group consisting of an oxygen atom joined to a hydrogen atom. Molecules possessing this group are soluble in water and are called alcohols.10
7300446762ketone groupA chemical group consisting of a carbon double bonded to oxygen (must be in middle of chain)11
7300446763ester groupA chemical group consisting of a carbon double bonded to oxygen and single bonded to another oxygen (must be in middler of chain)12
7300446764aldehyde groupA chemical group consisting of a carbon double bonded to oxygen and single bonded to hydrogen (must be at end of chain)13
7300446765carboxyl groupA chemical group consisting of a single carbon atom double-bonded to an oxygen atom and also bonded to a hydroxyl group14
7300446766ionized carboxyl groupA chemical group consisting of a single carbon atom double-bonded to an oxygen atom and also bonded to a negatively charged oxygen15
7300446767amino groupA chemical group consisting of a nitrogen atom bonded to two hydrogen atoms can act as a base in solution, accepting a hydrogen ion and acquiring a charge of 1⁺16
7300446769sulfhydryl groupA chemical group consisting of a sulfur atom bonded to a hydrogen atom.17
7300446770phosphate groupA chemical group consisting of a phosphate atom bonded to four oxygen atoms; important in energy transfer.18
