CARBOHYDRATES



Carbohydrates are polyhydroxy aldehydes or ketones with poly hydroxy derivatives. Section is divided carbohydrates into monosaccharides, disaccharides, oligosaccharides, polysaccharides, derivate of carbohydrates, glycoproteins, proteoglycans, and artificial sweeteners.
A. MonosaccharideMonosaccharide or simple sugar is a compound formed from a single polyhydroxy aldehyde or polyhydroxy unit ketones. Divided into two monosaccharide, aldose and ketosa yaito. aldose is a monosaccharide that has comtohnya aldehyde carbonyl group of glucose, while ketosa is a monosaccharide that has a ketone group example is fructose.
B. DisaccharideDisaccharide is a carbohydrate molecule composed of two monosaccharide molecules covalently bonded to each other. example is the disaccharide maltose (glucose + glucose), sucrose (glucose + fructose), lactose (glucose + galactose).
C. OligosaccharidesOligisakarida is a compound consisting of a combined 3-8 monosaccharide molecules. Oligosaccharides could be in the form trisakarida (eg: raffinose), tetrasakarida (eg: stakiosa), pentasakarida, and so on.
D. Derivatives KarbohiodratCarbohydrate derivatives are divided into three kinds, namely the form of acids (eg: glukarat amino acid, gluconate, glukoronat acids), amino sugars (eg: D-Glucosamine, D-Galaktosamin, D-Manosamin), and alcohol. Especially for the derivatives in the form of alcohol can be divided into two, namely that derived from the reduction of D-glucose (eg: D-sorbitol, D-mannose, D-Mannitol), and derived from the reduction of D-Fructose (eg: D-Sorbitol and D- mannitol)
E. PolysaccharidePolysaccharide is a biopolymer with makromolekul.merupakan a monomer unit is a monosaccharide or monosaccharide derivative. Polysaccharides can be divided into two, namely:a. Monomer unit derived from the type of polysaccharide called homopolisakarida (eg: starch, glycogen, dextrin, cellulose).b. Satuanya derived from a mixture of other types of species called heteropolisakarida (eg: mucopolysaccharide, khitin, khondroitin, and heparin).
F. GlycoproteinGlokoprotein is a protein that contains covalently bound carbohydrate. Carbohydrate binding generally is a single monosaccharide or oligosaccharide is relatively short. and usually dominate the protein molecule.
G. ProteoglycansBuffer is a structural polysaccharide, mucopolysaccharide composed of a berlekatan with protein, and a major part in this molecule is a carbohydrate (95%).
H. Artificial SweetenersSaccharin is an example of an artificial sweetener that has no nutritional value. Developed for people who have diabetes or obesity disorders. taste 400 times sweeter than ordinary sugar cane.
