Q

What is the function of a polysaccharide?

A

Energy storage molecules for structural support

17
Q

Describe dehydration synthesis (aka condensation) in two monsaccharides (honestly just read the answer first)

A

the hydrogen of one monomer combines with the hydroxyl group of another monomer, releasing a molecule of water in the process. The removal of a hydrogen from one monomer and the removal of a hydroxyl group from the other monomer allows the monomers to share electrons and form a covalent bond. Thus, the monomers that are joined together are being dehydrated to allow for synthesis of a larger molecule.

18
Q

What functional group is typically seen in a carbohydrate?

A

Carbonyl. C–O (polar)
