Carbohydrates
- Monosaccharides
- "The monomers that make up carbohydrates"
- Glucose
- Alpha
- Beta
- Has Six Carbon atoms
- Hexose Sugar
- Soluble structure makes it easily transported,
which helps its function as the main energy
source for humans and animals
- Ribose
- 5 Carbon Atoms
- Pentose Sugar
- Disaccharides
- Synthesis of Glycosidic Bonds
- 1) Hydrogen atom on one monosaccharide
bonds to (OH) group on another
- 2) This bond releases a water molecule
- 3) This is a condensation reaction
- "Two monosaccharides bonded together"
- Break down of Glycosidic Bonds
- Molecule of water reacts with
glycosidic bond, breaking it apart
- Hydrolysis
- Common Disaccharides
- Maltose
- Glucose + Glucose
- Sucrose
- Glucose + Fructose
- Lactose
- Glucose + Galactose
- Polysaccharides
- "More than two
monosaccharides
joined together"
- Starch
- Amylose
- Unbranched chain of A-Glucose.
Angles of bonds give it coil structure
- Compact and good for storage
- Amylopectin
- Branched chain of A-Glucose
- Branches allow glucose to be released
quickly as the enzymes can easily break
down the molecules to get to the bonds
- Main energy storage
material for plants
- Glycogen
- Main energy storage
material in animals
- Animals store excess glucose as glycogen
- Similar structure to Amylopectin
but many more branches
- Stored glucose can be released quickly
- Compact so its good for storage
- Cellulose
- Major component of plant cell walls
- Long, Unbranched chains of B-Glucose
- When beta molecules bond,
the chains are straight
- Cellulose chains joined
together by hydrogen bonds
- Strong fibres formed provide support
