Question

Both glucose and fructose are hexoses but glucose is aldose and fructose is ketoses sugars. What is the difference between aldoses and ketoses sugar? Structurally what makes glucose different from galactose

Answer 1

Answer:

Glucose and galactose are stereoisomers (have atoms bonded together in the same order, but differently arranged in space). They differ in their stereochemistry at carbon 4. Fructose is a structural isomer of glucose and galactose (has the same atoms, but bonded together in a different order).
