Document Summary

Carbohydrates: contain carbon, hydrogen, and oxygen. source of stored energy transport energy within organisms structural molecules give many organisms their shapes recognition or signaling molecules can trigger specific biological responses. Ribose and deoxyribose are the backbone of rna and dna. ~ ribose (has two oh side chains) vs deoxyribose (has one oh and one h side chains) (c6h12o6) include glucose, fructose, mannose, and galactose. are covalently bonded by condensation reactions that form glycosidic linkages to form disaccharides. Disaccharides: contain single glycosidic linkage between two monosaccharides. Sucrose (table sugar): linkage between glucose + fructose. Maltose (used in making beer): linkage between 2 glucose units. They often bonded to proteins and lipids on cell surfaces, where they serve as recognition signals. The human blood groups (abo_ get their specificity from oligosaccharides. Polysaccharides: are large polymers of monosaccharides connected by glycosidic linkages. chains can be branching: Glycogen highly branched polymer of glucose, main energy storage molecule in mammals.
