• Tyrosine Biochemistry:
• L-Tyrosine is an aromatic amino acid synthesized from the essential amino acid phenylalanine via phenylalanine hydroxylase.
• Precursor of Thyroid Hormones:
• In thyroid follicles, tyrosine residues within the thyroglobulin protein are iodinated to form monoiodotyrosine (MIT) and diiodotyrosine (DIT).
• Coupling of these iodotyrosines yields the active thyroid hormones triiodothyronine ($T_3$) and thyroxine ($T_4$), which regulate basal metabolic rate and larval metamorphosis in fish.
• Tyrosine is also the precursor for catecholamines (dopamine, norepinephrine, epinephrine) and melanin pigment.
• nalysis:
• (Give rise to thyroid hormones): Correct.
• (Serves as precursor of choline): Incorrect (methionine/phosphatidylethanolamine are precursors of choline).

Correct option: (1) Give rise to thyroid hormones
