Retinol metabolism (WP5188)
Homo sapiens
This pathway describes the metabolism of retinol. Retinol, more common known as vitamin A, is involved in various physiological processes in the human body. Vitamin A must acquired from the diet. When taken up, retinol metabolism is important to create all the different retinoid forms, such as retinoic acid and retinyl esters. All these types have their own function. There are many carries proteins and enzymes specific to retinoid metabolism involved in the processes.
