Answer 1

Hint Hormones are chemically heterogenous, non-nutrient substances and derive from diverse precursors such as amino acids, cholesterol, or phospholipids. Chemically they can be divided into two broad classes: those that are soluble in lipids and those that are soluble in water.
Complete Step-by-step answer:
The lipid-soluble hormones include steroid hormones and thyroid hormones. Thyroid hormones (T3 and T4) are synthesized by attaching iodine to the amino acid tyrosine. The benzene ring of tyrosine makes T3 and T4 soluble in lipids. So T3 and T4 are part of thyroid hormones.
Steroid hormones are the hormones that are derived from cholesterol. Some steroid hormones are cortisol, testosterone, estradiol, and progesterone.
Peptide hormones and protein hormones are amino acid polymers. Some peptide hormones are insulin, glucagon, pituitary, and hypothalamic hormones.
Amine hormones are synthesized by decarboxylation or modification of certain amino acids. For example- the catecholamines- epinephrine, norepinephrine, and dopamine are synthesized by modifying the amino acid tyrosine.
Hence the correct answer is option C.
Note: Histamine is synthesized from the amino acid histidine by mast cells and platelets. Serotonin and melatonin are derived from tryptophan. And several protein hormones like thyroid-stimulating hormone, have attached carbohydrate groups and are called glycoprotein hormones.
