Abstract Background Traditional Asian and African medicine use immature okra fruits (Abelmoschus esculentus) as mucilaginous food to combat gastritis. Its effectiveness is due to polysaccharides that inhibit the adhesion of Helicobacter pylori to stomach tissue. The present study investigates the antiadhesive effect in mechanistic detail. Methodology A standardized aqueous fresh extract (Okra FE) from immature okra fruits was used for a quantitative in vitro adhesion assay with FITC-labled

The genus Ocimum L. (basil) is a member of the Labiatae family which is an important economic and medicinal herb (Paton‚ Harley and Harley‚ 1999). The seeds of Ocimum basilicum are high in fiber and in some regions in Asia like Iran and India‚ basil seeds are frequently included in beverages (Sharbat) and ice desserts (Faloodeh) for aesthetic purposes as well as a source of dietary fibre (Hosseini-Parvar‚ Matia-Merino‚ Goh‚ Razavi et al.‚ 2010‚ Mäkinen and Pääkkönen‚ 1999). Basil seeds have reasonable

Background information: 1) What is diffusion? Movement of a particular type of molecule from an area of high concentration to an area of low concentration. 2) How is diffusion used by living cells? Living cells bring in food‚ water and oxygen‚ and excrete wastes through the process of diffusion 3) List two body systems in vertebrates that are dependent on diffusion Digestive system and respirational system 4) What is meant by the term metabolism the chemical processes that occur within a

and uni- or polyporate. The mean life of a pollen grain is strongly influenced by its water content at dispersal: the lower the water content‚ the longer the mean life. Very dehydrated pollen usually has a high cytoplasmic mono-‚ oligo- and polysaccharide content and no starch‚ unlike only slightly dehydrated pollen which contains starch

Title : Investigation of Action of Saliva and 3M HCl in Two Carbohydrates Solutions. Objective : To investigate the action of saliva and 3M hydrochloric acid in two carbohydrate solution. Result : Table 1 : The presence of starch and reducing sugar in the solution Observation Conclusion Solution A Benedict’s test : The transparent blue solution turns into opaque brick-red precipitate Iodine’s test : The clear colourless solution turns into transparent yellowish-brown

moisture Maintains osmoic balance and turgidity Saccharides : (a.k.a Carbohydrates) It is made up from Carbon‚ Hydrogen and Oxygen It is the main source of energy of cells. It can be divided into 3 groups – Monosaccharides‚ Disaccharides and polysaccharides. Monosacharides : They are known as simple sugars They cannot be hydrolysed/broken down into smaller units Eg. Glucose‚ Fructose‚ Galactose They are reducing sugars Disaccharides : They are formed by condensation reaction. Also
