deoxyribose.
What two functions do carbohydrates have?
structural molecules and energy stores
How are
monosaccharides classified?
based on the number of carbons they have: hexose=6 carbons, pentose= 5 carbons triose=3 carbons ect.

what are the two sugars of DNA
Deoxyribose and ribose(they are not structural isomers)
What is the difference between deoxyribose and ribose?
deoxyribose has one less oxygen on its second carbon
