Iodine in Thyroid Hormone
- Tyrosine Molar Mass = 181.19; x2 = 362.38
- Iodine Molar Mass 126.91; x2 = 253.8; x3 = 380.73; x 4= 507.64
- Note that the weight of T4 does NOT equal two tyrosines + 4 iodines since several atoms are removed when the tyrosines combine and when the iodines are attached to the tyrosines
- T4 molar mass is 776.87 grams/mol. C₁₅H₁₃I₄NO₄ Contains four iodine molecules = 507.64 gm; / 776.87 = 65.34% I
-
- 100 mcg T4 has 65.34 mcg of elemental iodine; 16.34 mcg released to make T3
- T3 molar mass is 650.98 grams/mol. Contains 3 iodine molecules = 380.73 gm; / 650.98 = 58.5 % I
- 5 mcg of T3 has 2.9 mcg of elemental iodine
- T2 molar mass is 525.09 grams/mol. Contains 2 iodine molecules = 253.8 gm; / 525.09 = 48.3% Iodine
- Di-Iodo-Tyrosine Molar Mass = 432.98. Contains 2 iodine molecules = 253.8 gm; / 432.98 = 58.62% Iodine
- Iodo-Tyrosine Molar Mass = 307.09. Contains 1 iodine molecule = 126.9 gm; / 307.09 = 41.32% Iodine
