Document Summary

Made of (ch2o)n where n refers to. Perform a variety functions in cell the number of carbon-hydrate groups contain carbonyl, several hyrodxyl and other functional groups with several c-h bonds. Carbohydrates based on sizes: monomers called monosaccharides --> one - sugar/simple sugars = e. g. sugars(see the table below, polymers called oligosaccharides --> few - sugars, large polymers called polysaccharides. Polysasccharides: starch, glycogen, cellulose, chitin and peptidoglycan. Cellulose, chitin: energy source: glucose is rapidly metabolized, energy storage: starch and glycogen, structural support: cellulose, chitin, cartilage and peptidoglycan. Structure: form longs strands which allows to form. These strands further criss - cross to form a tough sheets. Individual h bond is weak; but h+h+h bonds = strong. Function: form fibres that give cells and organisms strength and elasticity. Glycoproteins: are protein bonded to carbohydrates by covalent bonds (mostly to oligosaccharides). These are key in cell- cell recognition and cell- cell signalling. Help to identify part of your body.
