An important chlorophyll-derived diterpenoid essential oil, phytol (PYT) bio-metabolite, phytanic acid (PA) has a number of pathophysiological contributions. The PA metabolism and its plasma levels associated phenomena are continuously being researched on. This study aims to look at the complete current scenario of PA. The findings suggest that PA has anti-diabetic, cytotoxic, anticancer and anti-teratogenic activities. Although PA-mediated Refsum’s Diseases (RD), Sjogren-Larsson Syndrome (SLS) and prostate cancer are still controversial; Zellweger's Disease Hyperpipecolic Academia (ZDHA), Rhizomelic Chondrodysplasia Punctata (RCDP), Leber Disease (LD) and oxidative stress leading to mitochondrial and cardiac complications are also evident. In conclusion, PA may be a good biomarker of some pathophysiological phenomena and can be used for medico-pharmaceutical functions.
Key words: Phytanic acid, phytol bio-metabolite, biomarkers, pathophysiological contributions.
