Steroid hormones and thyroid hormone are lipid soluble. All other amino acid–derived hormones are water soluble. Hydrophobic hormones are able to diffuse through
The water-soluble products of acetylcholine-stimulated breakdown of phosphatidylinositol in mouse pancreas were analyzed by two different and independent procedures. There was an increased formation of free inositol throughout the period of phosphatidylinositol breakdown; no evidence was obtained for acetylchol...
It is a metal sulfide that, like other sulfides in its neighboring spots in the periodic table, is also only sparingly soluble in water. At room temperature, only a small amount of PbS will dissolve in water, resulting in a very low concentration of dissolved Pb2+ and S2- ions. This s...
