These forms travel with fat (since vitamin A is fat-soluble) to the small intestine. Within the lumen of the small intestine, bile emulsified fats incorporates vitamin A into micelles. Duodenal mucosal cells metabolise retinyl esters and provitamin A carotenoids to retinol (active form) in the body. Retinol is then further oxidised to retinal and then to retinoid acid. However, once digested, around 90% of  vitamin  A  is  stored  as  retinoic  acid  in  the  liver, so there is enough supply for  several months. ]]> 2019-04-01 06:29:05 UTC https://padlet.com/clare_dix/vitaminA/wish/347034699 https://padlet.com/clare_dix/vitaminA/wish/347035252 2019-04-01 06:32:03 UTC https://padlet.com/clare_dix/vitaminA/wish/347035252 Happening usually with people in Africa or southeast asia, due to lack of food access to vitamin A rich foods.
