The most abundant five-carbon sugars are L-arabinose, D-ribose, 2-deoxy-D-ribose,1 and D-xylose, which all are aldopentoses. ... The common six-carbon sugars (hexoses) are D-glucose, D-fructose, D-galactose, and D-mannose. They all are aldohexoses, except D-fructose, which is a ketohexose.
Is ribose a aldose or ketose?
Glucose, galactose, and ribose are called aldoses because they have an aldehyde group attached to their carbon-1. Fructose is called a ketose because it has a keto group attached to its carbon-2.
Is ribose an Aldopentose or Ketopentose?
Ribose is a sugar that is obtained by the hydrolysis of the RNA molecule. It has five carbon atoms in the ring. It contains aldehyde groups. Hence, it is aldopentose.
