General Information

General Information Comment Organism
physiological function phytol is phosphorylated to phytyl-phosphate and phytyl-diphosphate by two successive kinase activities. Phosphorylation of free phytol represents an alternative route for phytyl-diphosphate production as the precursor for chloroplast prenyl lipid synthesis. Lipid esters are produced after feeding phytol to Arabidopsis seedlings, and they also accumulate in large amounts in leaves during senescence. The predominant phytyl ester that accumulates during senescence is hexadecatrienoic acid phytyl ester Arabidopsis thaliana
