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:
