Lesson 971 of 1524
Biomolecules: Carbohydrates
Now that we’ve now seen all the common functional groups and reaction types, our focus has changed to looking at the major classes of biological molecules.
Practice this chapterNow that we’ve now seen all the common functional groups and reaction types, our focus has changed to looking at the major classes of biological molecules. Carbohydrates are polyhydroxy aldehydes and ketones.
They are classified according to the number of carbon atoms and the kind of carbonyl group they contain. Glucose, for example, is an aldohexose, a six-carbon aldehydo sugar.
