Steroids are considered to be lipids because they:
a) are essential components of cell membranes
b) are not soluble in water
c) are made of fatty acids
d) are hydrophilic compounds
e) contribute to atherosclerosis
Homework Answers
Steroids do not resemble fatty acids in its structure, steroids consist of 4 fused rings, but steroids are considered lipids because the these are hydrophobic so it is insoluble in water, like lipids so the answer is b) are not soluble in water
