Experientia Aims and scope Submit manuscript

Summary

By determination using fluorescence polarization measurements with 1,6-diphenyl 1,3,5-hexatriene, ergosterolreplaced pellicle and microsome membranes ofTetrahymena cells become less fluid, whereas those membranes from chimyl alcohol-fed cells are more fluid, when compared with the control native membranes.
