Question

Ovarian hormones are usually
(a)Proteinaceous
(b)Steroids
(c)Amines
(d)Modified amino acids

Answer 1

Hint: The group of hormones that are derived from cholesterol is typically ovarian hormones. They are produced as lipids. These hormones have been categorized into five classes on the basis of their receptors: glucocorticoids, mineralocorticoids, androgens, estrogens, and progestogens.

Complete answer:
Depending on the molecules they consist of, various hormones have different chemical characteristics. Hormones derived from cholesterol are steroids. These hormones are lipids in nature.
-Steroids are composed of hormones secreted by the adrenal cortex, testicles, and ovaries.
-Steroids are ovarian hormones. They are cholesterol-derived. Progesterone and estrogen are examples.
Corticosteroids (typically produced in the adrenal cortex, thus cortico) and sex steroids (typically made in the gonads or placenta) are the two classes of steroid hormones.
Steroid hormones help regulate metabolism, inflammation, immune functions, the balance of salt and water, the production of sexual characteristics, and the ability to resist disease and injury. The word steroid identifies both hormones released by the body and drugs created artificially that mimic the action of the steroids that occur naturally.

Additional Information:
  -Proteinaceous hormones are protein-made peptide hormones.
-Amines are hormones that are derivatives of amino acids.
-Some hormones are produced by amino acid alteration.
So, the correct answer is, ‘Steroids’.

Note: Various organs and body tissues, but predominantly the endocrine glands, such as the pituitary, thyroid, and gonads (testes and ovaries), contain hormones. Several kinds of hormones are apparently synthesized by each gland; more than 25 varieties are produced by the adrenal glands alone. The total number of hormones is still uncertain, but they each have a special function and chemical formula of their own. After a hormone is discharged into the capillaries or the lymph by its parent gland, it will travel a circuitous route through the bloodstream to affect cells, tissues, and organs (target organs) far from its original location.
