Only certain amounts of all nutrients or bioactive com pounds are available for use in physiological functions or for storage quit smoking support groups order nicotinell 17.5mg online. From the nutritional point of view quit smoking jacksonville florida discount nicotinell online american express, bioavailability is defined as the proportion of a nutrient or bioactive compound can be used for normal physiological functions [16] quit smoking aids that really work proven 35mg nicotinell. This term in turn includes two additional terms: bioacces sibility and bioactivity. Bioaccessibility has been defined as the fraction of a compound that is released from its food matrix in the gastrointestinal tract and thus becomes available for intes tinal absorption. Bioaccessibility includes the sequence of events that take place during food digestion for transformation into potentially bioaccessible material, absorption/assimilation through epithelial tissue and pre-systemic metabolism. Bioactivity in turn includes events linked to how the bioactive compound is transported and reaches the target tissue, how it in teracts with biomolecules, the metabolism or biotransformation it may undergo, and the gen eration of biomarkers and the physiologic responses it causes [12]. Depending on the in vitro method used, evaluation is made of bioaccessibility and/or bioactivity. In vitro methods have been developed to simulate the physiological conditions and the se quence of events that occur during digestion in the human gastrointestinal tract. In a first step, simulated gastrointestinal digestion (gastric and intestinal stages, and in some cases a salivary stage) is applied to homogenized foods or isolated bioactive compounds in a closed 134 Oxidative Stress and Chronic Degenerative Diseases - A Role for Antioxidants system, with determination of the soluble component fraction obtained by centrifugation or dialysis of soluble components across a semipermeable membrane (bioaccessible fraction). Simulated gastrointestinal digestion can be performed with static models where the prod ucts of digestion remain largely immobile and do not mimic physical processes such as shear, mixing, hydration. Dynamic models can also be used, with gradual modifications in pH and enzymes, and removal of the dialyzed components thereby better simulating the actual in vivo situation. All these systems evaluate the aforementioned term bioaccessibili ty, and can be used to establish trends in relative bioaccessibility. The principal requirement for successfully conducting experimental studies of this kind is to achieve conditions which are similar to the in vivo conditions. Interactions with other food components must also be taken into account, since they can influence the efficiency of digestion [12, 17]. A recent overview of the different in vitro digestion models, sample conditions and enzymes used has been published by Hur et al. En lipophilic compounds such as carotenoids and phytosterols, it is necessary to form mixed micelles in the duodenal stage through the action of bile salts, phospholipases and colipase. This allows the compounds to form part of the micelles, where they remain until uptake by the enterocytes [18]. In the case of lycopene, during digestion isomerization of trans-lycopene may occur with the disadvantage that trans-isomers are less soluble in bile acid micelles [19]. Salivary and gastric digestion exert no substantial effect on major phenolic compounds. However, polyphenols are highly sensi tivity to the mild alkaline conditions in pancreatic digestion, and a good proportion of these compounds can be transformed into other unknown and/or undetected forms [20]. Bioactive compounds such as dietary fiber, carotenoids, polyphenols and phytosterols un dergo very limited absorption, and may experience important modifications as a result of actions on the part of the intestinal microbiota. Small intestine in vitro models are devoid of intestinal microbes, and are designed to only replicate digestion and absorption processes; as a result, they are unable to provide information on intestinal fermentation processes. The incorporation of colonic/large intestine fermentation offers a better approximation to the in vivo situation, and allows us to study the effect/interaction between these compounds and the intestinal microbiota. In vitro colonic fermentation models are characterized by the inoculation of single or mul tiple chemostats with fecal microbiota (of rat or human origin) and operated under phys iological temperature, pH and anaerobic conditions. There are two types of colonic fermentation models: batch culture and continuous cultures.
