BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Cholesterol is a very important steroid to the body. It’s formed in the liver, brain tissue, bloodstream, and nerve tissue. It’s a precursor to certain hormones, such as testosterone. This means the body needs cholesterol to create these hormones.

Detailed explanation-2: -Now, those who are familiar with hormones may be confused between peptide and steroid hormones. While peptides come from amino acids, steroids are from lipids or fats. They also differ in these ways: A peptide hormone has a shorter lifespan than a steroid hormone, which still has to circulate around the body.

Detailed explanation-3: -All classes of steroid hormones, glucocorticoids, mineralocorticoids, and sex hormones, are derivatives of cholesterol. Synthesis occurs in the placenta and ovaries (estrogens and progestins), testes (testosterone), and adrenal cortex (cortisol, aldosterone, and androgens).

Detailed explanation-4: -The given statement is true. The cholesterol molecule acts as a biosynthetic source for all the steroidal hormones. The hormones such as progesterone, aldosterone, estrogen, cortisol, testosterone and corticosterone are included in the steroid hormones.
