Water-Soluble Vitamins ChallengeOnline version Vitamins that dissolve in water by Anoshia javed 1 A tuberculosis patient begins to feel numbness in his feet. His blood shows anemia even though iron stores are normal. The problem lies in a reaction that forms the first precursor of heme.

Flavoproteins remain inactive, and oxidation-reduction reactions slow down across many pathways.
