Are lipids soluble or insoluble in water Insoluble
Which type of lipid has NO carbon to carbon double bonds. Saturated lipids
Which type of lipid has at least 1 carbon to carbon double bonding Unsaturated lipids

What is the role of Glucose Most used respiratory substrate
Why do Monosaccharides provide a rapid source of energy? Easily absorbed as require little energy to be broken down.
Why is a disscaharide forming called a condensation reaction? Water molecules are released as 2 sugar molecule combine in the reaction.
What are polysaccharides? Polymers made up of many glucose monomers.
