This pathway is about carotenoid metabolism. It is mainly created by the NuGO focusteam on Carotenoid metabolism. Finally it was subject to a text mining workflow which added some additional entities. This pathway was inferred from Homo sapiens pathway [http://www.wikipathways.org/index.php?title=Pathway:WP716&oldid=30274 WP716(r30274)] with a 86% conversion rate. f7b e98 f92 da5 d8f f0b c8a da5 d87 f30 ebb d84 cd1 a8f e17 c13 fe3 a53 c78 e56 bbd e92 f61 e3d e5f 9627692 PubMed Vitamin D analogs affect the uptake and metabolism of retinol by human epidermal keratinocytes in culture.
