• Vitamin DCompared with: It is another fat-soluble vitamin, but it has distinct functions and metabolic pathways.

• RetinalNarrower topic: Retinal is produced from vitamin A forms obtained from food or recycled in tissues.

• VitaminBroader topic: Its role in vision makes deficiency especially damaging to the eyes.

• Vitamin ECompared with: Unlike vitamin E, vitamin A is not defined chiefly by lipid-chain antioxidant action.

• MargarineRelated: Some countries require or encourage vitamin A fortification of margarine.

• Vitamin A deficiencyNarrower topic: The deficiency results when the body lacks enough of this essential nutrient.

• Frederick Gowland HopkinsBroader topic: Elmer McCollum and Marguerite Davis later identified a fat-soluble growth factor in butterfat as vitamin A.

• IsotretinoinRelated: Isotretinoin is a synthetic compound related to vitamin A.

• Elmer McCollumBroader topic: McCollum’s feeding studies helped identify a growth-supporting factor in butterfat and egg yolk, later called vitamin A.

• Marguerite DavisBroader topic: Davis and McCollum’s rat-feeding experiments identified a growth-promoting factor later named vitamin A.

• Paul KarrerRelated: Karrer helped establish its structure and its relationship to carotene.

• Antimony trichlorideRelated: Its reaction with SbCl₃ forms the basis of the Carr–Price test.

• LiverRelated: Liver is an exceptionally concentrated dietary source, so large servings can exceed safe limits.
