Saturated in lipid membranes bound by lecithin, this molecule consists of two 1-1-dimethyl-2-ene-3-methyl-5-hydroxyl-cyclohexane rings linked by a 3-6-11-15 tetramethyl octadecene chain.  
Saturated in lipid membranes bound by lecithin, this molecule consists of two 1-1-dimethyl-2-ene-3-methyl-5-hydroxyl-cyclohexane rings linked by a 3-6-11-15 tetramethyl octadecene chain.  Its namesake cycle, which occurs at high light intensities, enables non-photochemical quenching by gaining or losing two epoxide groups.  At diminished light intensities, it transfers light energy to chlorophyll-alpha before decaying at lower temperatures to reveal anthocyanin and tannin.  FTP, name this carotenoid alcohol responsible for the yellow color of deciduous plants in autumn.
