Term
Alochol
Definition
An organic coumpound that contains a hydroxyl group (--OH) attached to an alkyl group
Term
dehyration
Definition
a reaction that involves the loss of a water molecule, in this casethe loss of water from an alochol and the simulataneous formation of an alkene
Term
disulfide
Definition
an organic compund that contains a disulfide group (--S--S--)
Term
elimination reaction
Definition
a reaction in which a molecule loses atoms or ions from its structure
Term
hydration
Definition
a reaction in which water is added to a molecule, e.g. the addition of the water to the alkene to form an alochol
Term
hydroxl group
Definition
the --OH functional group that is characteristic of alochols
Term
oxidation
Definition
a loss of electrons in organic compounds it may be recognized as a loss of hydrogen atoms or the gain of oxygen
Term
phenol
Definition
an organic compound that contains a hydroxyl group (--OH) attached to a benzene ring
Term
primary alochol
Definition
an alocol with the general formula RCH2OH
Term
reduction
Definition
the gain of electrons; in organic compounds it may be recognized by the gain of a hydrogen or loss of a oxygen
Term
secondary alochol
Definition
an alochol with the general formula R2CHOH
Term
tertiary alochol
Definition
an alochol with the general formula R3COH
Term
thiol
Definition
an organic compound that contains a thiol group (--SH)
Term
acetal
Definition
Term
addition reaction
Definition
a reaction in which two molecules add together to form a new molecule; often involves the addition of one molecule to a double or triple bond in an unsaturated molecule ; e.g. the addtion of alocol to a aldehyde or ketone to form a hemiacetal or hemiketal
Term
aldehyde
Definition
Term
carbonyl group
Definition
the functional group that contains a carbon-oxygen double bond:--C=O; the functional group found in aldehydes and ketones
Term
hemiacetal ***
Definition
the family of organic coumpounds formed via the reaction of one molecule of alochol with an aldehyde in the presence of an acid catalyst; hemiacetals have the following structure: *****
Term
hydrogenation
Definition
a reaction in which hydrogen (H2) is added to a double or triple bond
Term
ketone ****
Definition
a family of organic molecules characterized by a carbonyl group, the carbonyl carbon is bonded to two alkyl groups, two aryl groups, or one alkyl and one aryl group;ketones have the following general structures
Term
oxidation
Definition
a loss of electrons; in organic compounds it may be recognized as a loss of hydrogen atoms or the gain of oxygen
Term
acetyl coenzyme A
Definition
amolecule composed of coenzyme A and an acetyl group; the intermediate that provides acetyl groups for complete oxidation by areobic respiration
Term
adenosine triphosphate
Definition
a nucleotide composed of the purine adenine, the sugar ribose, and three phosphoryl groups; the primary energy storage and transport molecule used by the cells in cellular metabolism
Term
carboxyl group
Definition
the --COOH functional group; the functional group found in carboxylic acids
Term
carbonxylic acid
Definition
a member of the family or organic compounds that contain --COOH functional group
Term
ester
Definition
a organic compund that contains two alkyl and /or aryl groups attached to an oxygen atom; R--O--R, Ar--O--R, and Ar--O--Ar
Term
fatty acid
Definition
any member of the family of continous -chain carboxylic acids that generally contain four to twenty carbon atoms; the most concentrated source of energy used by the cell
Term
hydrolysis
Definition
a chemical change that involves the reaction of a molecule with water; the process by which molecules are broken into their constituents by addition of water
Term
oxidation
Definition
a loss of electrons; in organic compunds it may be recognized as a loss of hydrogen atoms or the gain of oxygen
Term
saponification
Definition
a reaction in which a soap is produced; more generally, the hydrolysis of an ester by an aqueous solution
Term
soap
Definition
any of a variety of the alkali metal salts of fatty acids
