Which of the following is true of unsaturated fats?
They are more common in animals than in plants.
They have double bonds in their fatty acid chains.
They generally solidify at room temperature.
They contain more hydrogen than do saturated fats having the same number of carbon atoms.
What component of amino acid structure varies among different amino acids?
long carbon-hydrogen tails of the molecule
presence of a central C atom
components of the R group
glycerol molecule that forms the backbone of the amino acid
Phospholipids and triglycerides both ________.
contain serine or some other organic compound
have three fatty acids
have a glycerol backbone
have a phosphate
How do phospholipids interact with water molecules?
The polar heads avoid water; the nonpolar tails attract water (because water is polar and opposites attract).
Phospholipids do not interact with water because water is polar and lipids are nonpolar.
The polar heads interact with water; the nonpolar tails do not.
Phospholipids dissolve in water.
