PATHOLOGY

Detailed explanation-1: -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.

Detailed explanation-2: -Steroid hormones are insoluble in water, and they are transported by transport proteins in blood. As a result, they remain in circulation longer than peptide hormones.

Detailed explanation-3: -The main class of lipid-derived hormone is the steroids which are derived from cholesterol and the eicosanoids. Steroid hormones include testosterone, estrogen and cortisol. Testosterone and estrogen are important regulators of reproductive function, secreted by both the testes and the ovaries.

Detailed explanation-4: -Examples of lipid-insoluble hormones are: Epinephrine. Thyroid hormone. Insulin.
