phytol การใช้

• The addition of water to the reaction cleaves the phytol off the enzyme.
• Diterpenes form the basis for biologically important compounds such as retinol, retinal, and phytol.
• Biosynthetically, pristane is derived from phytol and is used as a biomarker in petroleum studies.
• The phytol group consequently leaves the compound and replaces the serine residue on the chlorophyllase enzyme.
• Chlorophyll has a porphyrin chlorin ring surrounding a magnesium ion and attached to a phytol tail.
• These bug repelling properties of sweetgrass were later found by the American Chemical Society in the molecules phytol and coumarin.
• It was first published and described by Dionysios Mermygkas, Kit Tan and Artemios Yannitsaros in Phytologia Balcanica . ( Phytol.
• Also derived from isoprene are phytol, retinol ( vitamin A ), tocopherol ( vitamin E ), dolichols, and squalene.
• In ruminants, the gut fermentation of ingested plant materials liberates phytol, a constituent of chlorophyll, which is then converted to phytanic acid and stored in fats.
• Indirect evidence has been provided that, in contrast to humans, diverse non-human primates can derive significant amounts of phytol from the hindgut fermentation of plant materials.
• Insects, such as the sumac flea beetle, are reported to use phytol and its metabolites ( e . g . phytanic acid ) as chemical deterrents against predation.
• Although a wide range of terpene structures exist few of them are biologically significant, by contrast diterpenoids possess a rich pharmacology and include important compounds such as retinol and phytol.
• "' Phytol "'is an acyclic diterpene alcohol that can be used as a precursor for the manufacture of synthetic forms of vitamin E and vitamin K1.
• The functional isoprene units in biological systems are dimethylallyl pyrophosphate ( DMAPP ) and its isomer isopentenyl pyrophosphate ( IPP ), which are used in the biosynthesis of naturally occurring isoprenoids such as carotenoids, quinones, lanosterol derivatives ( e . g . steroids ) and the prenyl chains of certain compounds ( e . g . phytol chain of chlorophyll ).
