phenylpropanoid
Definition : Any organic aromatic compound with a structure based on a phenylpropane skeleton. The class includes naturally occurring phenylpropanoid esters, flavonoids, anthocyanins, coumarins and many small phenolic molecules as well as their semi-synthetic and synthetic analogues. Phenylpropanoids are also precursors of lignin.
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.
disaccharide
Definition : A compound in which two monosaccharides are joined by a glycosidic bond.
