In comparison to glucose, the ingestion of fructose results in a lower insulin peak and less marked fluctuations in blood glucose during exercise, potentially avoiding hypoglycaemia\u2010induced exhaustion.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:italic>Objectives<\/jats:italic>\n                    : To assess the capacity of the equine small intestine to absorb fructose and to determine the mechanism, molecular structure and properties of equine intestinal fructose transport.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:italic>Methods<\/jats:italic>\n                    : Using PCR\u2010based strategies, RNA isolated from equine small intestine and primers designed to homologous regions of the fructose transporter, GLUT5, cDNA of other species, we cloned and sequenced equine GLUT5 (eGLUT5). Northern and western blot analyses, in conjunction with immunohistochemistry, utilising eGLUT5 cDNA and antibodies, assessed expression of eGLUT5 along the longitudinal and radial axes of the small intestine. Functional properties of fructose transport in intestinal brush\u2010border membrane vesicles were measured using the rapid\u2010filtration technique.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:italic>Results<\/jats:italic>\n                    : eGLUT5 is expressed in the villus enterocytes with highest levels in duodenum&gt;jejunum and lowest in the ileum.
