Aldose 213595 224294093 2008-07-08T05:26:44Z Skyrainbow 4179230 /* List of aldoses */ [[Image:D-glyceraldehyde-2D-Fischer.png|thumb|right|140px|[[Fischer projection]] of D-[[glyceraldehyde]]]] An '''aldose''' is a [[monosaccharide]] (a simple [[sugar]]) containing one [[aldehyde]] group per [[molecule]] and having a [[chemical formula]] of the form Cn(H2O)n(n>=3). With only 3 [[carbon]] [[atom]]s, [[glyceraldehyde]] is the simplest of all aldoses. Aldoses [[isomer]]ize to [[ketose]]s in the [[Lobry-de Bruyn-van Ekenstein transformation]]. Aldose differs from ketose in that it has a [[carbonyl]] group at the end of the carbon chain whereas the carbonyl group of a ketose is in the middle; this fact allows them to be chemically differentiated through [[Seliwanoff's test]]. == List of aldoses == * [[Triose]]: [[glyceraldehyde]], dihydroxylacetone * [[Tetrose]]s: [[erythrose]], [[threose]] * [[Pentose]]s: [[ribose]], [[arabinose]], [[xylose]], [[lyxose]] * [[Hexose]]s: [[allose]], [[altrose]], [[glucose]], [[mannose]], [[gulose]], [[idose]], [[galactose]], [[talose]] == See also == * [[Carbohydrate]] * [[Ketose]] * [[Monosaccharide]] [[Category:Aldehydes]] [[Category:Aldoses|*]] [[Category:Monosaccharides]] {{biochem-stub}} {{Carbohydrates}} [[cs:Aldózy]] [[da:Aldose]] [[de:Aldosen]] [[es:Aldosa]] [[eo:Aldozo]] [[fr:Aldose]] [[it:Aldoso]] [[ja:アルドース]] [[pl:Aldozy]] [[pt:Aldose]] [[ru:Альдозы]] [[fi:Aldoosi]] [[zh:醛糖]]
