Chapter 5 Carbohydrates Flashcards
Monosaccharide
One sugar, encompasses the monomers
Carbohydrate
=sugar = saccharide 1. Monosaccharide 2. Oligosaccharide 3. Polysaccharide Role of energy
Oligosaccharide
Few sugars ( small polymers)
Polysaccharide
“Many-sugars” ( large polymers)
Aldose
Carbonyl group at end of Carbon chain
Ex) glucose -> aldohexose
Ketose
Carbonyl group in middle of Carbon chain
Ex) fructose-> ketohexose
Disaccharide
Only 2 sugars are linked together
Glycosidic linkage
Monosaccharides polymerize when a condensation reaction occurs between two hydroxyl groups
Polysaccharides differ in structure
Delta -1,4 glycosidic linkage (cellulose)
Alpha-1, 4 glycosidic linkage ( starch, glycogen)
Structural Polysaccharides-Starch
Entirely alpha-1,4 glycosidic linkage
A storage in plant cell
Structural Polysaccharides-Cellulose
A structural support in cell walls of plant
A polymer delta 1,4 glycosidic linkage
Structural Polysaccharides- Glycogen
A highly BRANCHED storage in animal
A polymer of alpha 1, glycosidic linkage
Glycoprotein
Sugar+protein
Cells recognize another cell ( identify the type or species of the cell)
