Biochemistry - Part 5 - Lipids

Lipids are structurally __________ biomolecules.

• Terpenoids

• Vitamin E

Waxes are classified as:

• Non-hydrolyzable simple lipids

• Hydrolyzable simple lipids

• Non-hydrolyzable complex lipids

• Hydrolyzable complex lipids

Which lipid class contains phospholipids and sphingolipids?

• Simple lipids

• Complex lipids

• Non-hydrolyzable lipids

• Fat-soluble vitamins

Which of the following is NOT a non-hydrolyzable lipid?

• Vitamin D

• Triglyceride

• Sterol

• Terpenoid

The parent compound of all phospholipids is:

• Ceramide

• Phosphatidic acid

• Lecithin

• Sphingosine

Ceramide is the parent compound of:

• Phospholipids

• Waxes

• Triglycerides

• Sphingolipids

The lipid bilayer of membranes is:

• Hydrophobic

• Covalently bonded
