| CHEBI:71690 |
|
| A xanthophyll that is β-D-glucopyranose in which the hydroxy groups at positions 1 and 6 have been acylated by an all-trans-2,6,10,15,19,23-hexamethyltetracosa-2,4,6,8,10,12,14,16,18,22-decaenoyl group and a 12-methyltetradecanoyl group, respectively. Staphyloxanthin is responsible for the characteristic yellow-golden colour which gives the bacterium Staphylococcus aureus its name. |

biological pigment
An endogenous molecular entity that results in a colour of an organism as the consequence of the selective absorption of light.
virulence factor
Any toxin secreted by bacteria, viruses, fungi or protozoa enabling them to achieve colonisation of a niche in the host, inhibit or evade the host's immune response, enter and exit cells, or obtain nutrition from the host.
metabolite
Any intermediate or product resulting from metabolism. The term 'metabolite' subsumes the classes commonly known as primary and secondary metabolites.

staphyloxanthin is a Structural Derivative of
|
carotenoid
Definition :
One of a class of tetraterpenoids (C40), formally derived from the acyclic parent, psi,psi-carotene by hydrogenation, dehydrogenation, cyclization, oxidation, or combination of these processes. This class includes carotenes, xanthophylls and certain compounds that arise from rearrangement of the skeleton of psi,psi-carotene or by loss of part of this structure. Retinoids are excluded.
terpene
Definition :
A hydrocarbon of biological origin having carbon skeleton formally derived from isoprene [CH22C(CH3)CH2CH2].
carotene
Definition :
Hydrocarbon carotenoids.
aldohexose
Definition :
A hexose with a (potential) aldehyde group at one end.
aldose
Mass :
90.07790
Formula :
C2H4O2(CH2O)n
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.
hexose
Definition :
Any six-carbon monosaccharide which in its linear form contains either an aldehyde group at position 1 (aldohexose) or a ketone group at position 2 (ketohexose).
D-hexose

180.156
Formula :
