[Lipids and proteolipids in membranes of the smooth endoplasmic reticulum of rat enterocytes. Vitamin D-dependent calcium binding].
The lipid and proteolipid composition of endoplasmic reticulum smooth membranes from rat enterocytes in normalcy and under D-hypovitaminosis is studied to show the Ca2+-binding with these components. These membranes in vitamin D-deficiency are established to differ in the cholesterol content. Proteolipids 1 and 2 are isolated from the lipid fraction of membranes. Their amino acid composition is determined. The vitamin D-dependent binding of Ca by the proteolipid fraction is shown.
