Having discussed the introduction of simple sugars in the last record, now comes the turn of the disaccharide sugars plastic cup dispenser and polysaccharides discuss anyway. Disaccharide sugar commonly found in our environment, even quite closely with our daily use such as maltose (in honey and fruits), plastic cup dispenser lactose (in milk products) and sucrose (cane sugar). This requirement is also important as a source plastic cup dispenser of instant energy as the importance of simple sugars. Polysaccharides plastic cup dispenser are long chains of sugar units which are mostly composed of simple sugars and disaccharides surplus in humans, animals plastic cup dispenser and plants. Note this time discussing the types of bonds sugar di- and polysaccharides. Sugar disaccharide disaccharide unit consisting of only two simple sugars, and naming many refer to glycosidic bonds and acetal groups that connect between the two. Disaccharide sugars can be defined as a combination of two simple plastic cup dispenser sugars (monosaccharides) are linked by acetal bonds between groups hemiacetals a simple sugar alcohol with a group of simple sugars other. Acetal plastic cup dispenser bond is called bond-1,4'-glycosidic α or β-1,4'-glycosidic if these two simple sugars linked between C-1, a simple sugar with C-4 other sugars. α- and β- O refers to the position in the glycosidic bond that bound to the anomeric carbon. The "prime" refers to the C-4 is not of the same bracelet. plastic cup dispenser Maltose and cellobiose disaccharide Both have in common, namely; unit contained sugar is D -glukosa and they exist in the form of α- and β- on hemiacetals group. plastic cup dispenser Their differences are at the acetal bond; maltose has α-1,4'-glycosidic and β-cellobiose has 1,4'-glycosidic. Lactose It is one example of a disaccharide sugar that has two different units of simple sugars, namely D and D -galaktosa -glukosa. Acetal bond is β-1,4'-glycosidic plastic cup dispenser and hemiacetals groups located on glucose unit. Polysaccharide polymer structure is a combination of simple sugar units at least 10 units and it can reach several thousand units of simple sugars. The simplest example is starch (in tuberous plants plastic cup dispenser and fruits), glycogen (in animals) and chitin (on the surface of the shell of the animal). Acetal bond is still important in relation simple sugar units. Bond-1,4'-glycosidic α or β-1,4'-glycosidic produce unbranched polysaccharide. For example, amylose plastic cup dispenser and the cellulose. The existence of other acetal bond as 1,6'-glycosidic and 1,3'-glycosidic together 1,4'-glycosidic bond, branched polysaccharides can be obtained. For example amylopectin and glycogen. With a view to re-cover the configuration of many simple sugars and sugar correlate with the ability to form glycosidic bonds, plastic cup dispenser we can imagine various kinds of disaccharides and polysaccharides that may exist in our environment. Perhaps less noticed her presence, but the potential to find out various species of flora and fauna hard to deny.
