Phytane has many structural isomers. Among them, crocetane is a tail-to-tail linked isoprenoid and often co-elutes with phytane during gas chromatography (GC) due to its structural similarity. Phytane also has many stereoisomers because of its three stereo carbons, C-6, C-10 and C-14. Visa mer Phytane is the isoprenoid alkane formed when phytol, a constituent of chlorophyll, loses its hydroxyl group. When phytol loses one carbon atom, it yields pristane. Other sources of phytane and pristane have also been proposed than … Visa mer The major source of phytane and pristane is thought to be chlorophyll. Chlorophyll is one of the most important photosynthetic pigments in plants, algae, and cyanobacteria, … Visa mer Pristane/Phytane ratio Pristane/phytane (Pr/Ph) is the ratio of abundances of pristane and phytane. It is a proxy for redox conditions in the depositional environments. The Pr/Ph index is based on the assumption that pristane is formed … Visa mer Phytane is a non-polar organic compound that is a clear and colorless liquid at room temperature. It is a head-to-tail linked regular isoprenoid with chemical formula C20H42. Phytane has many structural isomers. Among them, Visa mer In suitable environments, biomolecules like chlorophyll can be transformed and preserved in recognizable forms as biomarkers. … Visa mer Inferences from Pr/Ph on the redox potential of source sediments should always be supported by other geochemical and geological data, such as sulfur content or the C35 … Visa mer • Phytol • Pristane • Biomarker • Crocetane • Archaeol • Tocopherols Visa mer WebbSubstance Name: Phytane RN: 638-36-8 UNII: 27UZX1Q8TR InChIKey: GGYKPYDKXLHNTI-UHFFFAOYSA-N Molecular Formula C20-H42 Molecular Weight 282.552 All Links to Resources Names & Synonyms Registry Numbers Structure Descriptors NLM Resources (File Locators) DrugPortal PubChem PubMed PubMed Central Other Resources (Internet … WebbFigure 1.6 Pristane and Phytane Chemical Structures..... 12 Figure 1.7 Diesel Chromatogram ...
