Acceleration of Vitamin E Deficiency by Torula Yeast. II. Effect of Torula Yeast Ash and Lipid

Summary

When added to a purified basal diet low in vit. E and selenium, the ash of Torula yeast was found to promote exudative diathesis. This effect could not be demonstrated by any of the minor elements, nor by any of the major components, of the ash. The lipid isolated from Torula yeast also promoted exudates; this effect could be duplicated by tall oil. A combination of lipid and ash from Torula yeast produced an incidence of exudative diathesis similar to that produced by an equivalent amount of the intact yeast. A combination of tall oil and a synthetic ash was just as effective. It is concluded that the anti-vit. E property of Torula yeast is due essentially to both its unsaturated fatty acid and mineral contents. The relatively high content of dienoic acid in the lipid of Torula yeast was confirmed.
