Exercise 1
What are the structural and functional differences between
simple and complex carbohydrates?
Simple carbs have one or two sugar units. Complex carbs have hundreds or thousands. Simple carbs use basic
glycosidic bonds. Complex carbs feature intricate, often branched, chains. Simple carbs are monosaccharides or
disaccharides. Complex carbs are polysaccharides.
