Document Summary
7 carbohydrates and glycobiology through "disaccharides contain a. Glycoconjugates - proteins or lipids act as signals that determine the intracellular location or metabolic fate of these hybrid molecules. Monosaccharides - simple sugars - single polyhydroxy aldehyde or ketone unit. Oligosaccharides - short chains of monosaccharides joined by glycosidic linkages. Polysaccharides - sugar polymers with 20 or more monosaccharide units. Two families of monosaccharides are aldoses and ketoses. Monosaccharides are colorless, crystalline solids that are freely soluble in water but insoluble in nonpolar solvents. The monosaccharide is an aldose if the carbonyl group is at the end of the carbon chain and it is a ketose if the carbonyl group is at any other position. The simplest monosaccharides are the two 3 carbon trioses: glyceraldehyde, aldotriose, and dihydroxyacetone. Fischer projection - drawing of the sugar from a certain perspective. If a molecule has n stereocenters, then it will have 2 n. Epimers are two sugars that only differ in configuration stereoisomers.
