FAQ
Frequently Asked Questions
Glucose (specifically D-glucose) is one of the most common and biologically important aldoses.
An aldose has its carbonyl group (C=O) as an aldehyde at the end of the carbon chain (carbon 1). A ketose has its carbonyl group as a ketone within the carbon chain (typically at carbon 2).
No, fructose is a ketose. Its carbonyl group is a ketone on the second carbon atom.
You will only encounter 'aldose' in scientific contexts: textbooks, research papers, and lectures in biochemistry, organic chemistry, biology, nutrition science, and related laboratory work.
