Concept #1: Lipids

Concept #2: Lipids

Practice: Which type of fatty acids only contain Carbon-Carbon single bonds?

a) Unsaturated.

b) Saturated.

c) Trans fats.

d) Steroids.

Concept #3: Lipids

Practice: A triglyceride is a form of _______ composed of ___________.

a) Lipid ; fatty acids & Glucose.

b) Lipid ; Fatty acids & Glycerol.

c) Carbohydrate ; Fatty acids only.

Concept #4: Lipids

Practice: How do phospholipids interact with water molecules?

a) The polar heads avoid water; the nonpolar tails attract water (because water is polar and opposites attract).

b) Phospholipids do not interact with water because water is polar and lipids are nonpolar.

c) The polar heads interact with water; the nonpolar tails do not.

d) Phospholipids dissolve in water.

e) Phospholipid.

Practice: Choose the correct statement about biological waxes:

a) They contain at least one steroid molecule.

b) They are fatty acids bound to long chain alcohol molecules.
