Tyrosine vs. Thyroxine: What's the Difference?

Edited by Huma Saeed || By Sumera Saeed || Published on January 6, 2024
Tyrosine is an amino acid used in protein synthesis. Thyroxine (T4) is a hormone produced by the thyroid gland, influencing metabolism.

Key Differences

Tyrosine is one of the 20 standard amino acids used by cells to synthesize proteins. Thyroxine, on the other hand, is a hormone derived from tyrosine, produced by the thyroid gland.
