| Term | Definition |
|---|---|
| carbohydrates | -sugars and polymers of sugars -monosaccharides, disaccharides, and polysaccharides |
| monosaccharides | -simple sugars -multiple CH2O -most common in glucose as nutrients and fuel for cells -cellular respiration -building blocks for amino acids -monomers for disaccharides and polysaccharides |
| disaccharides | -two monosaccharides joined by covalent bonds -sucrose most common -monosaccharides are glucose and fructose -plants transfer carbs from roots to leaves in sucrose |
| polysaccharides | -polymer with many sugars joined by dehydration reaction -storage and structural polysaccharides |
| storage polysaccharides | -starch -glycogen |
| structural polysaccharides | -cellulose forms cell walls in plants -chitin forms exoskeleton of bugs/anthropods |
| elements in carbohydrates | -Carbon -Hydrogen -Oxygen |
| functional groups | -one carbonyl (C=O) -many hydroxyl (OH) |
| monomer of carbohydrates | -monosaccharide |
| polymer of carbohydrates | -polysaccharide |
| starch | -storage polysaccharide in plants |
| glycogen | -storage polysaccharide in animals -stored in liver and muscle cells |
