Phytan is 2,6,10,14-tetramethylhexadecane, C 20 H 42 is an aliphatic hydrocarbon belonging to diterpenoids . Colorless liquid with a boiling point of 69-71 ° C, density 0.791 g / ml, CAS number 638-36-8. Unlike pristan , which is formed by decarboxylation of phytol , phytan has one additional carbon atom , that is, it is its homologue . Fitanil is the corresponding substituent; such functional groups were found in large numbers in the phospholipids of thermophilic archaea membranes [1] . Such a substance is, for example, caldarcheol , a compound containing two linked phytanyl chains.
Content
Unsaturated phytans
- Fiten - unsaturated compound, correlated with phytan, having one double bond . This is the corresponding double bond alkene in position 2.
- Wick is a functional group corresponding to 2-phytene (2,6,10,14-tetramethylhexadecen-2-yl) contained in some important biological molecules. The alcohol corresponding to phytene is phytol .
- Geranilgeranen is a polyunsaturated form of phytan. A suitable substituent is geranyl geranyl.
Application
Used as a biomarker in fuel research [2] .
