2-Hexaprenyl-3-methyl-5-hydroxy-6-methoxy-1,4-benzoquinol
2-Hexaprenyl-3-methyl-5-hydroxy-6-methoxy-1,4-benzoquinol is an ubiquinone derivative that is an intermediate in ubiquinone-6 biosynthesis. Ubiquinone (also known as coenzyme Q) is an isoprenoid quinone that functions as an electron carrier in membranes. In eukaryotes ubiquinone is found mostly within the inner mitochondrial membrane, where it functions in respiratory electron transport, transferring two electrons from either complex I (NADH dehydrogenase) or complex II (succinate-ubiquinone reductase) to complex III (bc1 complex). The quinone nucleus of ubiquinone is derived directly from 4-hydroxybenzoate , while the isoprenoid subunits of the polyisoprenoid tail are synthesized via the methylerythritol phosphate pathway , which feeds isoprene units into the Polyprenyl Biosynthesis pathways. The number of isoprenoid subunits in the ubiquinone side chain vary in different species. For example, Saccharomyces cerevisiae subsp (S288c) has 6 such subunits, Escherichia coli K-12 has 8, rat and mouse have 9, and Homo sapiens has 10. The ubiquinones are often named according to the number of carbons in the side chain or the number of isoprenoid subunits. The ubiquinone biosynthesis pathway has been elucidated primarily by the use of mutant strains that accumulate pathway intermediates. 2-Hexaprenyl-3-methyl-5-hydroxy-6-methoxy-1,4-benzoquinol is a substrate for hexaprenyldihydroxybenzoate methyltransferase, mitochondrial precursor (COQ3) and can be generated from 2-hexaprenyl-3-methyl-6-methoxy-1,4-benzoquinol. Then it can be converted to ubiquinol-6.(BioCyc). 2-Hexaprenyl-3-methyl-5-hydroxy-6-methoxy-1,4-benzoquinol is an ubiquinone derivative that is an intermediate in ubiquinone-6 biosynthesis.

24-Methylcholestanol ferulate
24-methylcholestanol ferulate is a member of the class of compounds known as steroid esters. Steroid esters are compounds containing a steroid moiety which bears a carboxylic acid ester group. 24-methylcholestanol ferulate is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). 24-methylcholestanol ferulate can be found in corn, which makes 24-methylcholestanol ferulate a potential biomarker for the consumption of this food product.
