AbstractAbstract
[en] It is shown that the formation of taurine from sulphate by the chicken embryo involves the reduction of sulphate to sulphite (I), the synthesis of cysteic acid (II) and its decarboxylation (Ill). The reaction (I) takes place in the vitellin sac. The reaction (II) results from the condensation of the sulphite with a-amino-acrylic acid and is carried out by the yolk. The enzymes responsible for the decarboxylation (III) are distributed both in the embryo and in its appendages. (author)

On demontre que la formation de taurine a partir de sulfate par l'embryon de poulet implique la reduction du sulfate en sulfite (1), la synthese de l'acide cysteique (Il) et sa decarboxylation (III). La reaction (I) a lieu dans le sac vitellin. La reaction (II) resulte de la condensation du sulfite avec l'acide a-amino-acrylique et est realisee par le jaune. Les enzymes assurant la decarboxylation (III) sont repartis aussi bien dans l'embryon que dans ses annexes. (auteur)Original Title
