This is the colour reaction of iodine in starch purchase 500mg zithromax amex antibiotic resistance mayo clinic, a confirmatory test for the presence of starch buy zithromax 500mg overnight delivery bacteria 5 types. Amylopectin contains branches (nonlinear), approximately one in every 20 to 25 glucose units. Starch soaks up secretions and helps to render injured parts less liable to bacterial infections. As a dusting powder for application to chafings and excoriations, it is used either alone or mixed with zinc oxide, boric acid and other similar substances. Like amylopectin, 0 0 glycogen contains a complex branching structure with both 1,4 and 1,6 links, but it is larger than amylopectin (up to 100 000 glucose units) and much more branched. It has one end glucose unit (where glucose can be added or released) for every 12 units and a branch in every six glucose units. Cellulose Cellulose, the most abundant natural organic polymer, consists of several thousands of D-glucose units linked by 1,4 -0 b-glycoside bonds as in cellobiose. Different cellulose molecules can then interact to form a large aggregate structure held together by hydrogen bonds. Nature uses cellulose mainly as a structural material to provide plants with strength and rigidity. Therefore, human digestive enzymes cannot hydro- lyze b-glycosidic links between glucose units. In human beings, starch (but not cellulose), is hydrolyzed enzymatically to produce glucose. While there is no food value in cellulose for humans, cellulose and its derivatives are commercially important. Cellulose is used as raw material for the manufacture of cellulose acetate, known commercially as acetate rayon, and cellulose nitrate, known as guncotton. Natrosol (hydroxyethylcellulose) is a nonionic water-soluble polymer that is extensively used as a thickener, 6. Natrosol is also used in cosmetic preparations as a thickening agent for shampoos, conditioners, liquid soaps and shaving creams. Carbohydrate antibiotics Antibiotics that contain one or more amino sugars within the molecule are called carbohydrate antibiotics. For exam- ple, gentamicin is composed of three different units: purpurosamine, 2-deoxystreptamine and garosamine. Therefore, human beings need an external supply of this vitamin, mainly from fresh vegetables and fruits. In many pharmaceutical preparations ascorbic acid is used as an antioxidant preservative. Ascorbic acid is highly susceptible to oxidation, and oxidized easily to dehydroas- corbic acid. Biologically these are important compounds as they are an integral part of cell membranes. The carbohydrates in the membrane are covalently bonded to proteins (glycoproteins) or with lipids (glycolipids). A glycoside is composed of two moieties: sugar portion (glycone) and non-sugar portion (aglycone or genin). For example, the hydrolysis of salicin produces a glucose unit and salicyl alcohol. Many of these glycosides are formed from phenols, polyphenols, steroidal and terpenoidal alcohols through glycosidic attachment to sugars. Among the sugars found in natural glycosides, D-glucose is the most prevalent one, but L-rhamnose, D- and L-fructose and L-arabinose also occur quite frequently. Of the pentoses, L-arabinose is more common than D-xylose and the sugars often occur as oligosaccharides. The sugar moiety of a glycoside can be joined to the aglycone in various ways, the most common being via an oxygen atom (O-glycoside).
