| Abstract: | The dolichol concentrations in rat and trout liver were found respectively to be 50-59 and 16-21 micrograms/g using three experimental methods: densitometric scanning of thin-layer plates, colorimetric assay and HPLC analysis. By HPLC of benzoylated dolichols, the distribution of the dolichols according to the number of their isoprene residues, was determined in rat and trout liver. The major component was dolichol -18 in rat and dolichol -19 in trout liver. Dolichyl phosphate concentrations were found to be 6-7 micrograms/g of rat liver and 8-9 micrograms/g of trout liver by densitometric scanning of thin-layer plates. |
