Small quantities of a wheat albumin have been isolated from two varieties, Cappelle‐Desprez and Manitou. Both proteins have the same mobility on starch‐gel electrophoresis in an acidic buffer. The molecular weights from gel electro‐phoresis in sodium dodecyl sulphate agree within the limits of experimental error. Amino‐acid analyses are close enough to suggest that the proteins have the same composition. A revised molecular weight of 13 000 is put forward for a previously isolated Cappelle‐Desprez albumin, 1 the C‐terminal amino acid of which has been shown to be valine.
