D.Not all lipids have fatty acids. The operational definition of a lipid is a biomolecule is that is sufficiently hydrophobic to be more soluble in an organic solvent than in water. The common theme to their structures is a high percentage of hydrocarbon character.

E.Most lipid hormones are steroid hormones, which are usually ketones or alcohols and are insoluble in water. Steroid hormones (ending in '-ol' or '-one') include estradiol, testosterone, aldosterone, and cortisol. ... Amino acid-derived hormones and protein hormones are water-soluble and insoluble in lipids.
