Question

Label the following property of phospholipids, triglycerides,
or both.
1)) Complete the table.

phospholipids
triglycerides
provide insulation for the body

contain a glycerol molecule

contain a hydrophilic head

are amphipathic

Answer 1

phospholipids / triglycerides / both

- provide insulation for the body — triglycerides
(stored fat provides thermal insulation)

- contain a glycerol molecule — both
(both have a glycerol backbone)

- contain a hydrophilic head — phospholipids
(phosphate-containing polar head group)

- are amphipathic — phospholipids
(have both hydrophilic head and hydrophobic tails)
