Metabolite Identification
Common Name4-Methylpentanal
Description4-Methylpentanal, also known as isohexanal or isocaproaldehyde, belongs to the class of organic compounds known as alpha-hydrogen aldehydes. These are aldehydes with the general formula HC(H)(R)C(=O)H, where R is an organyl group. 4-Methylpentanal is an extremely weak basic (essentially neutral) compound (based on its pKa). Within humans, 4-methylpentanal participates in a number of enzymatic reactions. In particular, pregnenolone and 4-methylpentanal can be biosynthesized from 20a,22b-dihydroxycholesterol; which is mediated by the enzyme cholesterol side-chain cleavage enzyme, mitochondrial. In addition, 17a-hydroxypregnenolone and 4-methylpentanal can be biosynthesized from 17a,20a-dihydroxycholesterol through the action of the enzyme cholesterol side-chain cleavage enzyme, mitochondrial. In humans, 4-methylpentanal is involved in the metabolic disorder called the 11-beta-hydroxylase deficiency (cyp11b1) pathway. Outside of the human body, 4-Methylpentanal has been detected, but not quantified in, milk (cow). This could make 4-methylpentanal a potential biomarker for the consumption of these foods.
