Abstract
Summary
Values for total sulfur content of the rat adrenal gland and its protein, lipid and water-soluble moieties have been determined. The total sulfur as determined (0.63% of the dry weight) is much lower than previously reported values. Adrenal glands were incubated briefly with radioactive cysteine and the tissue was then analyzed for total uptake of the isotope and its distribution within the fractions. The effect of added adrenocorticotropin upon this uptake and distribution was observed. The hormone preparation causes a marked reduction in uptake by the soluble fraction, and a rise in the uptake by the lipid and protein fractions. The concentration of the isotope in the lipid sulfur is very striking.
