Term
amino group
Definition
A functional group that consists 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.
Term
carbonyl group
Definition
A functional group present in aldehydes and ketones and consisting of a carbon atom double-bonded to an oxygen atom.
Term
carboxyl group
Definition
A 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.
Term
enantiomer
Definition
One of two molecules that are mirror images of each other.
Term
functional group
Definition
A specific configuration of atoms commonly attached to the carbon skeletons of organic molecules and usually involved in chemical reactions.
Term
geometric isomer
Definition
One of several organic compounds that have the same molecular formula but differ in the spatial arrangements of their atoms.
Term
hydrocarbon
Definition
An organic molecule consisting only of carbon and hydrogen.
Term
hydroxyl group
Definition
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.
Term
isomer
Definition
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.
Term
organic chemistry
Definition
The study of carbon compounds (organic compounds).
Term
phosphate group
Definition
A functional group important in energy transfer.
Term
structural isomer
Definition
One of several organic compounds that have the same molecular formula but differ in the covalent arrangements of their atoms.
Term
sulfhydryl group
Definition
A functional group consisting of a sulfur atom bonded to a hydrogen atom (--SH).
Term
alcohol
Definition
contains hydroxyl group
Term
aldehyde
Definition
molecule with carbonyl group on its end of carbon skeleton
Term
amine
Definition
molecule with amino groups
Term
carboxylic acid
Definition
compound containing carboxyl group
Term
Ketone
Definition
compound with carbonyl group of which thae carbon atom is double bonded to two other carbons
Term
Thiol
Definition
compounds containg sulhydryl groups
