Glucagon-like peptide 2 (GLP-2) levels determined by radioimmunoassay using a specific antibody for intact GLP-2 (amino acid residues 1 to 33) (20). Sugar probe absorption is reported as the proportion of orally administered probe recovered in urine after an overnight collection, quantified using high-performance liquid chromatography (23,34). 3-OMG 3-O-methyl glucose
