Isomers

• Many chemical bonds in glucose release energy when broken down in respiration (used for ATP), each step is controlled by (highly specific)enzymes; plants and animals respire alpha glucose but not beta glucose
• Structural Isomers: They all have slightly different properties; monosaccharides have the same molecular formula but different structural formulae
• Stereoisomers: Glucose has two, they vary slightly in structure - called α-glucose and β-glucose (they have different properties)
