picoline

Many animals can convert extra tryptophan (an amino acid) to niacin, but cats have large amounts of the enzyme picolinic acid carboxylase that interferes with the conversion.

Briefly, through a series of enzymatic steps, tryptophan is normally converted into kynurenine, then to 3-hydroxykynurenine via kynurenine 3-monooxygenase (KMO; B2, NAD[P.sup.+]), then 3-hydroxyanthranilic acid is formed by kynureninase (KYNU; B6), and proceeds down the pathway to become either acetyl-coA, picolinic acid or quinolinic acid, which is further converted into NA[D.sup.+] through another series of enzymatic steps.

At the time, test results detected trace amounts (less than 16 parts per billion) of clopyralid or picloram, members of the picolinic acid family of persistent herbicides, which are highly effective, highly specific broadleaf herbicides.

Genomic and functional analyses of the 2-aminophenol catabolic pathway and partial conversion of its substrate into picolinic acid in Burkholderia xenovorans LB400.

The results show the various organic acids present in the soil like (dl-Tartaric acid 5-Formylvanillic acid p-Phenylenediacetic acid 3 3-Dimethylacrylic acid r-Pentyloxybenzoic acid Glycolic acid Mesaconic acid Picolinic acid along with other compounds of benzene.

Chromium picolinate (CrPic), also named as picolinic acid chromium, is a convenient form of chromium that is used more efficiently than some other forms of chromium [10].
