What are the structural differences between a saturated and an unsaturated fat?
Unsaturated fats have a double bond between at least two carbons in the fatty acid tail and those same carbons have only a single hydrogen bonded to each.
-
Explain how polymers are related to monomers.
Polymers are comprised of monomers.
