WebOverview A pentose is a monosaccharide with five carbon atoms . They either have an aldehyde functional group in position 1 ( aldopentoses ), or a ketone functional group in position 2 ( ketopentoses ). The aldopentoses have three chiral centres ("asymmetric carbon atoms") and so 8 different stereoisomers are possible. The 4 D -aldopentoses are: Webfunction. It is a 4 carbon compound so it would be classified as an aldotetrose. The carbonyl group in II is a ketone function, so it will be a ketose. It is a six carbon molecule, making it a ketohexose. Shown below is the structure of How would you classify it? It is an aldopentose.
