Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

A component of a cell’s outer membrane and is the precursor of several other steroids; such as the male sex hormone testosterone

A	Steroid
B	Lipid
C	Cholesterol
D	Triglyceride

Explanation:

Detailed explanation-1: -Pregnenolone (P5), is a major precursor of most steroid hormones, including the androgens, estrogens, progestogens, and adrenal steroids (see Figure 4-6). P5 is a neurosteroid, meaning that it is expressed in the brain and can act locally to acutely regulate neuronal function (Ratner et al., 2019).

Detailed explanation-2: -Cholesterol is the most common steroid and is the precursor to vitamin D, testosterone, estrogen, progesterone, aldosterone, cortisol, and bile salts. Cholesterol is a component of the phospholipid bilayer and plays a role in the structure and function of membranes.

Detailed explanation-3: -Steroid hormones are derived from a common precursor molecule, cholesterol, via the metabolic pathway schematically outlined in Figure 21-1.
