BIOC 3021 Chapter 11 Review Set Questions
and Answers
Sterols - Answers✓✓as hormones. have a perhydrocyclopentaneophenanthrene ring structure.
not aromatic and not planar
Fatty acids - Answers✓✓linear hydrocarbons with 1 carboxyl group at one end and many
methylene groups in the side chain.
generally have even number of C because they are synthesized and degraded 2 C at a time.
most range from 12-24 C
hydrophobic character increases as the chain length increases
double bonds increases the solubility of the compounds in water and decreases their melting
point
Triaglycerols - Answers✓✓major storage lipids
3 FA esterified to glycerol
relatively non-polar, highly reduced(saturated)

Phosphoglycerols - Answers✓✓membrane components.
2 FA, glycerol, phosphate, ionic or polar alcohol
FA at position 2 = unsaturated
FA at 1 = saturated
phosphatidyl choline (lecithin) is its derivative
Sphingolipids - Answers✓✓membrane functions. similar overall structure and similar capacity
in biological membranes
Poluisoprenoid - Answers✓✓resembles polymers of isoprene but have a very different
biochemical origin. Vitamin A and beta-carotene.
Which lipid types serve as energy storage material, membrane components, hormones,
biological detergents, insulating material and vitamins? - Answers✓✓Energy storage -
Triaglycerols
Membrane components - phosphoglycerol (phospholipids)
hormones - sterols
biological detergents - bile acids
Insulating material - phospholipid & sphingomyelin
