Match each structure with the TYPE of lipid class it represents. Not all answers (i.e. lipid classes) need be used; some structures may share the same class.

Matching pairs:
? Fatty acid
? Sphingophospholipid
? Glycerophospholipid
? Triacylglycerol
? Cholesterol

------------------------------------------------

Consider the lipid structures (A through E) below.

Which structures contain saturated fatty acids or saturated fatty acid derivatives? Select all answers that apply.
a. A ("A" is a saturated fatty acid, a fatty acid with only single bonds in the hydrocarbon chain.)
b. B ("B" is an unsaturated fatty acid. Notice the double bonds in the structure.)
c. C ("C" is a saturated fatty acid, a fatty acid with only single bonds in the hydrocarbon chain.)
d. D ("D" contains two saturated fatty acyl chains and one unsaturated fatty acyl chain.)
e. E ("E" chains two unsaturated fatty acyl chains.)

Therefore, all are correct, except B.
