Sodium deoxycholate is white to cream crystalline powder

Sodium deoxycholate is an ionic detergent for the solubilization of membrane-bound proteins.

Sodium deoxycholate is used as a component in cell lysis buffers.

ChEBI: Sodium deoxycholate is a bile acid salt. It contains a deoxycholate.

Sodium deoxycholate (SDC) is an anionic detergent which has been used both to destroy infectious viruses and to fractionate viral components. Sodium deoxycholate begins to bind to the virus at less than 0.1 mM free equilibrium concentration. It causes lysis of the viral membrane at 0.9 +/- 0.1 mM free equilibrium concentration when 2.2 +/- 0.2 - 103 mol of sodium deoxycholate are bound per mol of the virus. The liberation of proteins from the membrane begins at 1.5 +/- 0.1 mM sodium deoxycholate, and the proteins released are virtually free from phospholipids above 2.0 mM sodium deoxycholate. The overall mechanism of sodium deoxycholate solubilization of the viral membrane resembles that of Triton X-100 and sodium dodecyl sulphate, except that with sodium deoxycholate, the various stages of membrane disruption occur at about 10-fold higher equilibrium free detergent concentrations. At sodium deoxycholate concentrations higher than 2.3 mM, the viral spike glycoproteins can be separated by sucrose gradient centrifugation or gel filtration into constituent polypeptides E1, E2 and E3[1-2].

Solubilizes fats for absorption in the intestines.

Recrystallise it from EtOH and dry it in an oven at 100o. The solution is freed from soluble components by repeated extraction with acid-washed charcoal. [Beilstein 10 IV 1608.]
