title: [Biohydrogenation of erucic acid (22:1 n-9 cis) in an "artificial rumen". II) Effect of pH, potential hydrogen donors and type of anaerobiosis].
abstract: The possibility of dietary C18 unsaturated fatty acids double bonds biohydrogenation, which normally occurs in ruminants, has been investigated in the case of erucic acid (22:1 n-9 cis). The results have shown that, while oleic acid is always converted into hydrogenation intermediates and stearic acid, to various extent, erucic acid does not undergo hydrogenation process, unrelated to the incubation conditions applied. Data are discussed on the basis of the different structure of erucic and oleic acids.
