Question

Which statement/statements is/are true? (May have several correct answers):

a.The fatty acid tails of membrane lipids point inward into the lipid bilayer away from the aqueous environment.

b.Proteins with only the amino acids D, E, K, and R on their surface can be found exclusively in the interior of a lipid bilayer.

c.An amino acid such as F would most likely be found in the interior of proteins that are soluble in a hydrophobic environment.

d.Cholesterol is an amphipathic molecule.

e.An unsaturated fatty acid has no double bonds in its fatty acid tail.

f.none of them are true

The true statements are : a , c , and d.

The fatty acid tails are hydrophobic in nature , the reason they are pointed away from the aqueous environment.

The amino acid such as phenylalanine is neutral , non polar and hydrophobic in nature , due to which it is found in interior of proteins.

Cholesterol is amphipathic , as it is partly soluble and partly insoluble in water.
