Biochemistry — Vitamins, Minerals & Trace Elements

💊 Vitamins, Minerals & Trace Elements

The cofactors that keep every metabolic pathway running. Each deep dive below covers functions, deficiency states, excess/toxicity, and the board-favorite clinical correlations.

☀️
Fat-Soluble Vitamins
A, D, E, K — stored in adipose, released unpredictably. Vitamin A toxicity, D-resistant rickets, K-dependent clotting factors, warfarin, and the antioxidant hierarchy.
B Vitamins & Cofactors
B1 through B12 plus Vitamin C. The 3-dehydrogenase pattern, Wernicke-Korsakoff, pellagra, megaloblastic anemia, and why B9 vs B12 is the board's favorite trick.
Minerals & Trace Elements
Calcium, magnesium, zinc, copper, iron + chromium, selenium, molybdenum, manganese, fluoride. Wilson's vs Huntington's, Menke's, and why fluoride kills glycolysis.

Vitamin K & Coagulation
Gamma-carboxylation, warfarin vs heparin, the heparin bridge timeline, HIT-1 vs HIT-2, LMWH, Factor V Leiden, gut flora, and hemorrhagic disease of the newborn.
