The 28 pages that link to Vitamin B12, each with the reason it gives.

• Coordination chemistryBroader topic: Its cobalt coordination sphere changes during biologically important reactions.

• CobaltRelated: Cobalt’s biological role in humans occurs chiefly as the metal center of this vitamin.

• VegetarianismRelated: People avoiding animal foods may need fortified foods or supplements to obtain reliable B12.

• HemeCompared with: Cobalamin is another metal-bearing biological cofactor, but its central metal is cobalt.

• Vitamin B12 deficiencyNarrower topic: Deficiency is the clinical consequence of inadequate available vitamin B12.

• FolateCompared with: B12 deficiency can trap folate in a form unavailable for other reactions, producing overlapping blood abnormalities.

• Plant-based dietRelated: People avoiding animal foods need a reliable fortified-food or supplement source.

• Vegetarian cuisineRelated: Reliable B12 sources require attention in vegetarian diets that exclude animal foods.

• PorphyrinCompared with: Its related tetrapyrrole ring binds cobalt but differs structurally from porphyrins.

• VitaminBroader topic: Deficiency can impair blood formation and cause neurological injury.

• Fat-soluble vitaminCompared with: Despite being water-soluble, it can be stored extensively in the liver.

• Dorothy HodgkinRelated: Hodgkin solved its intricate structure in 1956, revealing its cobalt-centered architecture.

• HydroxocobalaminNarrower topic: Hydroxocobalamin is one member of this vitamin family.

• Intrinsic factorRelated: Intrinsic factor binds this vitamin and carries it to the site of absorption.

• One-carbon metabolismRelated: Methionine synthase uses it to transfer folate-bound methyl groups to homocysteine.

• Vitamin B6Compared with: B12 deficiency can also cause neurological and blood abnormalities, but has different causes and treatments.

• ThiamineCompared with: Its deficiency can also cause neurological problems, but through different pathways and often with anemia.

• CyanocobalaminNarrower topic: Cyanocobalamin is one member of this broader family of vitamin B₁₂ forms.

• HomocysteineRelated: Methionine synthase depends on B12 to transfer a methyl group to homocysteine.

• IleumRelated: Vitamin B12 bound to intrinsic factor is absorbed in the terminal ileum.

• HomocystinuriaRelated: Cobalamin deficiency or processing defects can cause homocysteine accumulation.

• Methylmalonic acidNarrower topic: Its coenzyme forms enable the reaction that prevents methylmalonic acid from accumulating.

• Raw foodismRelated: Strict raw vegan diets need a reliable B12 source, usually supplementation or fortified foods.

• PescetarianismRelated: Seafood, eggs, and dairy can supply B12, depending on the foods included.

• Lacto-ovo vegetarianismRelated: Dairy and eggs provide some B12, though intake still depends on food choices.

• George MinotBroader topic: The active nutritional factor behind the benefit of liver therapy.

• William P. MurphyRelated: Later research identified B12 as the active nutritional factor behind the benefit Murphy observed.

• LiverRelated: Liver supplies abundant B12, making it a notably nutrient-dense food.
