A recently discovered peroxygenase from the fungus Marasmius rotula (MroUPO) is able to catalyze the progressive one-carbon shortening of medium and long-chain mono- and dicarboxylic acids by itself alone, in the presence of H2 O2 . The mechanism, analyzed using H218 O2 , starts with an α-oxidation catalyzed by MroUPO generating an α-hydroxy acid, which is further oxidized by the enzyme to a reactive
The biocatalytic oxidative tandem decarboxylation of C7–C18 dicarboxylic acids to terminal C5–C16 dienes was catalyzed by the P450 monooxygenase OleT with conversions up to 29 % for 1,11-dodecadiene (0.49 g L–1). The sequential nature of the cascade was proven by the fact that decarboxylation of intermediate C6–C11 ω-alkenoic acids and heptanedioic acid exclusively gave nonconjugated 1,4-pentadiene;

The present invention discloses a novel process for the chain shortening of carboxylic acids having a hydrocarbon chain, catalyzed by a peroxygenase, preferably by a fungal peroxygenase from Marasmius rotula (MroUPO), in the presence of a peroxide. The mechanism starts with an α-oxidation generating an α-hydroxy acid, which is further oxidized to a reactive α-keto intermediate whose decarboxylation yields the one-carbon shorter acid.

A method for constructing a metabolic profile of a mammalian (such as a human) subject from one of more urine samples from the subject uses magnetic resonance mass spectrometry (MRMS) for the rapid and inexpensive quantitative measurement of at least 4,000 urinary chemical substances in a single analysis. The method for metabolic profiling measures thousands of urinary substances in a urine sample from a mammalian subject in a single assay. Many of these substances can be of mammalian metabolic origin. The measurements of types and amounts of urinary substances can be correlated to assessments of present or future health of the subject.
