GLUT5 is the primary facilitative transporter responsible for D-fructose absorption in the small intestine.
Your body uses a specific transporter called GLUT5 to absorb fructose (fruit sugar) from your small intestine. This is a dedicated pathway distinct from the primary glucose absorption mechanisms.
GoodSupportsHIGH confidence
GLUT5 is relevant for D-fructose absorption... GLUT5 in the BBM and BLM is responsible for transport of D-fructose across the BBM and BLM.

- High luminal glucose concentrations trigger the translocation of the facilitative transporter GLUT2 to the brush border membrane (BBM) of enterocytes, thereby increasing the capacity for D-glucose absorption.Good
- SGLT1 abundance in the brush border membrane increases in response to high luminal glucose, mediating high-capacity glucose absorption.Good

- Initial treatment for type 2 diabetes should be a combination of metformin and either an SGLT-2 inhibitor or a GLP-1 receptor agonist to achieve cardiorenal protection, rather than monotherapy or older agents like sulfonylureas.Strong
- For patients with specific monogenic obesity syndromes (leptin deficiency, POMC/PCSK1/LEPR mutations), targeted pharmacotherapy (recombinant leptin or setmelanotide) is highly effective and should be prioritized, unlike in polygenic obesity.Strong
- Continued weekly administration of 2.4 mg subcutaneous semaglutide prevents weight regain and promotes further weight loss in adults with overweight or obesity, whereas switching to placebo results in significant weight regain.Strong
