24. juli 2017 opdateret af: Christoffer Martinussen, Hvidovre University Hospital

Detaljeret beskrivelse

Dietary triglycerides are hydrolyzed during digestion to two fatty acids and one 2-monoacyl glycerol. The study will investigate the effects of these different fat components on gut hormone secretion in gastric bypass operated patients and non-operated BMI-matched controls.
