Absorption of Folic Acid from Potato Chips in Humans

The effect of pH on folic acid absorption in man.

1. Pteroylmonoglutamic acid (PteGlu) absorption has been measured by using the technique of small-intestinal perfusion with tritiated PteGlu in normal subjects and in patients with coeliac disease. 2. At similar intrajejunal pH, patients with untreated coeliac disease have significantly less PTEGlu than normal subjects and patients with treated coeliac disease. 3. The "resting" pH in the jejunu...

The clinical and experimental studies on the metabolism of folic acid using tritiated folic acid. I. Absorption tests of tritiated folic acid in man.

given 30 minutes after an injection of 15 mg of non-radioactive FA. The urinary excretion of 3H-FA was estimated in following 24 hours. In some cases the fecal excretion of 3H-FA was meas ured for successive four days. 3. The urinary excretion of 3H-FA in eleven normal subjects ranged from 37.6 to 57.9 per cent of the oral dose, with a mean of 48.4 per cent and a standard deviation of 7.4 per c...

The science of pesticide-free potato chips.

The urinary excretion of orally administered tritium-labeled folic acid as a test of folic acid absorption.

By FREDERICK A. Kuis nn I HE ABSORPTION of folic acid occurs primarily in the proximal small intestine and is thought to be mediated, in part at least, by an active transport 2 l)iminished absorption of folic acid commonly occurs in disease characterized by diffuse atrophy of the jejunal mucosal villi, such as idiopathic steatorrhea ( non-tropical sprue, gluten enteropathy ) and tropical sprue ...

Plasma Level of Homocysteine, Folic acid and Cobalamine in Patients suffered from myocardial infarction

Abstract Introduction: methionine. Many reports confirm the correlation between hyper homocysteinemia and cardiovascular disease. This study was aimed at determining the effect of B12 and folate deficiency on the homocysteine level after myocardial infarction. Homocysteine is produced by demethylation of Materials and methods: study were patients with myocardial infarcti...
