cofactor
An organic molecule or ion (usually a metal ion) that is required by an enzyme for its activity. It may be attached either loosely (coenzyme) or tightly (prosthetic group).

FMN
Mass :

nucleobase
Definition :
That part of DNA or RNA that may be involved in pairing.
phosphorus oxoacid
Definition :
A pnictogen oxoacid which contains phosphorus and oxygen, at least one hydrogen atom bound to oxygen, and forms an ion by the loss of one or more protons.
oxoacid
Definition :
A compound which contains oxygen, at least one other element, and at least one hydrogen bound to oxygen, and which produces a conjugate base by loss of positive hydrogen ion(s) (hydrons).
monosaccharide
Definition :
Parent monosaccharides are polyhydroxy aldehydes H[CH(OH)]nC(2O)H or polyhydroxy ketones H1[CHOH]n1C(2O)[CHOH]m1H with three or more carbon atoms. The generic term 'monosaccharide' (as opposed to oligosaccharide or polysaccharide) denotes a single unit, without glycosidic connection to other such units. It includes aldoses, dialdoses, aldoketoses, ketoses and diketoses, as well as deoxy sugars, provided that the parent compound has a (potential) carbonyl group.
carbohydrate
Definition :
Any member of the class of organooxygen compounds that is a polyhydroxy-aldehyde or -ketone or a lactol resulting from their intramolecular condensation (monosaccharides); substances derived from these by reduction of the carbonyl group (alditols), by oxidation of one or more hydroxy groups to afford the corresponding aldehydes, ketones, or carboxylic acids, or by replacement of one or more hydroxy group(s) by a hydrogen atom; and polymeric products arising by intermolecular acetal formation between two or more such molecules (disaccharides, polysaccharides and oligosaccharides). Carbohydrates contain only carbon, hydrogen and oxygen atoms; prior to any oxidation or reduction, most have the empirical formula Cm(H2O)n. Compounds obtained from carbohydrates by substitution, etc., are known as carbohydrate derivatives and may contain other elements. Cyclitols are generally not regarded as carbohydrates.
pentose
Definition :
A five-carbon monosaccharide which in its linear form contains either an aldehyde group at position 1 (aldopentose) or a ketone group at position 2 (ketopentose).
pentitol
Definition :
An alditol obtained by reduction of any pentose.
alditol
Definition :
A carbohydrate that is an acyclic polyol having the general formula HOCH2[CH(OH)]nCH2OH (formally derivable from an aldose by reduction of the carbonyl group).
alditol
Definition :
A carbohydrate that is an acyclic polyol having the general formula HOCH2[CH(OH)]nCH2OH (formally derivable from an aldose by reduction of the carbonyl group).
