It was usually thought that ethylidene compounds such as (III) were the precursors of ethyl compounds such as (VIII) and this has been proved recently in the case of poriferasterol (IX) which contained four deuterium atoms when Ochromonas malhamensis was grown in presence of [Me-2H3] ...

The change of ion-ion and ion-solvant type interactions in ternary systems as regard to the binary systems, are evidenced by the δ and δ o deviation functions. To calculate these functions use is made of the deviations from additivity of Gibbs thermodynamic potential in the ternary system. ...
