Question

Quizplus · Accepted Answer

Human sex hormones, such as estrogen and testosterone, are considered to be lipids because they are not soluble in water. Lipids are defined as hydrophobic or amphiphilic molecules that do not dissolve in water but dissolve in organic solvents, such as alcohol or chloroform. Sex hormones are predominantly produced and stored in adipose tissue, which is a type of lipid-based tissue. However, human sex hormones are not made of fatty acids or essential components of cell membranes, nor do they contribute to atherosclerosis.
