General Information

General Information Comment Organism
metabolism H2O2 is essential for the iodination of the tyrosyl residues to produce mono- and diiodotyrosine that are the precursors for the synthesis of thyroid hormones T3 and T4. interaction of endogenous D-Asp, D-AspO, and D-aspartate racemase in thyroid gland constitutes an additional biochemical pathway for the production of H2O2 and consequently for the synthesis of thyroid hormones, overview Mus musculus
