Document Summary

8:36 pm: dietary: from food sources, non idgestible, intrinsic in plants. Fermentable: b glucan, gum, pectin, some polydextrose, resistant dextrins, rs: gel forming: pectin, gum arabic, b glucan, phyllium, prebiotic: fructans, polydextrose. Soluble: pectin, b glucan, gum arabic, resistant starch/dextrins, phyllium, polydextrose. Solubility in water: soluble: slow transit time, low nutrient absorption, delay gastric emptying. Insoluble: fast transit time, more fecal excretion, low nutrient absorption: water holding capacity. Fiber absorb and interact with fa, cholesterol, bile: prevent formation of micelles. Fermentability: easily fermentabl: gum arabic, pectin, psyllium, fructan, resistant starch, polydextrose, prebiotic benefits, generation of scfa, non fermentabl: cellulose, lignin, some hemicellulose. Ethanol free form: no separation from large molecules/food matrix needed, directly absorbed via diffusion into si. Goes to liver 90%, enter hepatocytes via diffusion, aslo excreted at lungs, kidneys, sweat. Ethanol oxidation pathway (alcohol dehydrogenase: nad+-> nadh+h+ to mitochondria etc via malate aspartate shuttle-> 5 atp, acetate->acetyl coa->tca or fa.
