title: A modified procedure for the preparation of UDP-beta-L-(U-14C)rhamnose.
abstract: This paper describes the synthesis of UDP-L-(U-14C)rhamnose from UDP-D-(U-14C)glucose and NADPH using an enzyme preparation of Nicotiana tabacum var. Xanthi. A procedure to separate UDP-l-rhamnose from the other compounds in the reaction mixture is described. Optimal separation was achieved in ethanol 95%-1 M ammonium acetate (pH 3.8) (7:3, v/v) at 30 degrees C.
