Addition of citral, a mixture of geranial and neral, resulted in the production of geranic acid and citronellic acid, whereas the addition of citral or citronellal resulted in the production of citronellic acid, suggesting that citronellic acid might be produced through the conversion of citral to citronellal followed by the oxidation of citronellal. The peaks of geranic acid and citronellic acid converted from nerol were smaller than those converted from geraniol (Figure1a and c). The citronellols are also monoterpene alcohols; they are the hydrogenated forms of geraniol. (2003) Terpenoid metabolism in wild-type and transgenic Arabidopsis plants. Using the terpene, the researchers suppressed pro-inflammatory signaling pathways to reduce the rats inflammatory responses. In this study, we focused on geraniol and nerol as the substrates of terpenoid biosynthesis and tried to clarify whether or not conversions of geraniol and nerol to terpenoids other than citronellol, linalool, and -terpineol take place under the catalysis of S. cerevisiae enzymes. Genes encoding alcohol dehydrogenase were selected, and effects of gene deletion on concentrations of residual geraniol and produced geranic acid, citronellic acid, and citronellol after 10-d cultivation were investigated. Is citronella oil toxic? You may find the smell relaxes you for meditative moments when used in aromatherapy. The geraniol 10-hydroxylase was purified from seedlings and cell cultures, and the activity reconstituted. The organic phase was collected using a Pasteur pipette for measurement by GC-MS.
