pantoyl Biochem.|ˈpæntɔɪl, ˈpæntəʊaɪl| [f. pantothenic a. + -yl.] The optically active radical HOCH2C(CH3)2CH(OH)CO{b1}, present in pantothenic acid.
1942Barnett & Robinson in Biochem. Jrnl. XXXVI. 357 Dr. McIlwain..suggested a simplified nomenclature, following which we have adopted a system based on the name ‘pantoyl’ for the α:γ-dihydroxy-β:β-dimethyl⁓γ-butyryl radicle. 1971Analytical Biochem. XLII. 8 Pantoyl lactone, the other product of hydrolysis of pantothenates, can be easily and directly evaluated by gas chromatography, providing a simpler method for the quantitation of Vitamin B5. Hence pantoylˈtaurine, a sulphonic acid, C8H17O6NS, which inhibits the action of pantothenic acid in microorganisms.
1942Biochem. Jrnl. XXXVI. 366 The degree of inhibition by pantoyltaurine depends on the amount of pantothenic acid present in the medium. 1954E. E. Snell in Sebrell & Harris Vitamins II. ix. 680 Addition of pantoyltaurine increased the lag phase and decreased the rate of growth during the first half of the logarithmic phase of Streptococcus hemolyticus. 1968Compar. Biochem. & Physiol. XXVII. 649 When pantoyltaurine, an analogue of pantothenic acid, was incorporated into the culture media, inhibition of growth [of Trypanosoma lewisi] was observed. |
