Vitamin A2 aldehyde

Description

Vitamin A2 aldehyde, also known as 3-dehydroretinal or retinene 2, belongs to the class of organic compounds known as retinoids. These are oxygenated derivatives of 3,7-dimethyl-1-(2,6,6-trimethylcyclohex-1-enyl)nona-1,3,5,7-tetraene and derivatives thereof. Thus, vitamin A2 aldehyde is considered to be an isoprenoid. Based on a literature review a small amount of articles have been published on Vitamin A2 aldehyde.
