## Abstract Transport rates of the nonphosphorylated D‐glucose analogs 6‐deoxy‐D‐glucose and D‐xylose were measured in quiescent and serum‐stimulated cultures of mouse 3T3 cells, in SV40‐transformed 3T3 cells (SV101), and in a density revertant cell line derived from SV101 (Fl‐SV101). Initial rates

Abstract
6‐Deoxy‐D‐glucose and D‐xylose, structural homomorphs of D‐glucose that lack a 6‐hydroxyl group or a 6‐hydroxymethyl group, respectively, are transported efficiently by mouse 3T3 cells, with good affinity and high specificity for the D‐glucose transport system. Since these analogs lack the 6‐hydroxyl group, which is the site of phosphorylation of glucose by hexokinase, they are taken up and are recoverable from cells in an unchanged state. Thus, 6‐deoxy‐D‐glucose and D‐xylose offer advantages as transport substrates over 2‐deoxy‐D‐glucose, which is phosphorylated by intercellular hexokinases, and 3‐O‐methyl‐D‐glucose, which shows a lower specificity for the D‐glucose transport system.
