Brit.

/ˈpantəʊʌɪl/,

/ˈpantəʊɪl/,

/ˈpantɔɪl/, U.S.

/ˈpæn(t)oʊˌɪl/

Origin: Formed within English, by derivation. Etymons: pantothenic adj., -oyl suffix.

Etymology: < pant- (in pantothenic adj.) + -oyl suffix.

Chemistry.

An acyl radical, —C(O)CH(OH)C(CH₃)₂CH₂OH, present in pantothenic acid and some related compounds. Usually attributive.

1942 J. W. Barnett & A. F. Robinson in Biochem. Jrnl. 36 357 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.

1995 Phytochemistry 40 1617 The pantoyl residue is related to central roles of metabolism through pantothenic acid and CoA.

Compounds

pantoyl lactone n. the γ-lactone of pantoic acid, C₆H₁₀O₃, a degradation product of pantothenic acid and an intermediate in its synthesis.

ΚΠ

1944 Jrnl. Amer. Chem. Soc. 66 425/1 A pH of 3.7–4.0 was chosen since the formation of pantoyl lactone is rapid and complete in this range.

1971 Analyt. Biochem. 42 8 Pantoyl lactone..can be easily and directly evaluated by gas chromatography, providing a simpler method for the quantitation of Vitamin B₅.

1995 New Scientist 25 Feb. 16/2 Three simple organic molecules which would have been abundant in the primeval soup—pantoyl lactone, Β-alanine and cysteamine—will join up to form a molecule called pantetheine if they are heated to around 40°C.

pantoyltaurine n. an analogue of pantothenic acid containing taurine in place of β-alanine, which acts as a competitive inhibitor of pantothenic acid and reduces growth in microorganisms; C₈H₁₇O₆NS.

1942 Biochem. Jrnl. 36 366 The degree of inhibition by pantoyltaurine depends on the amount of pantothenic acid present in the medium.

1968 Compar. Biochem. & Physiol. 27 649 When pantoyltaurine..was incorporated into the culture media, inhibition of growth [of Trypanosoma lewisi] was observed.
