Document Summary

There are 4 general classes of molecular components in living cells: Living cells contain simple molecules of each of these and large polymers of carbs, amino acids, and nucleic acids. When polymers of any class become extremely large, they are called macromolecules: carbohydrates. Most common monosaccharides have 3,5,or 6 carbon atoms: glyceraldehyde (c3h6o3, ribose (c5h10o5, glucose (c6h12o6, fructose (c6h12o6, galactose (c6h12o6) Glucose, fructose, and galactose are structural isomers because they have the same formula but different structures, functions, and properties. Aldoses have their carbonyl group at the end of the carbon chain (includes glyceraldehyde, ribose, glucose, and galactose) Ketoses have their carbonyl group within the carbon chain (includes dihydroxyacetone, ribulose, and fructose) A different anomeric form of glucose ( -ring structure) Bonds formed between the monosaccharides in disaccharides and polysaccharides are glycosidic bonds by dehydration synthesis or condensation reactions. Involves the loss of one water molecule as monomers are joined.
