Study Notes
Food Macromolecules
- Glucose is not classified as a macromolecule.
- Consumption of food in lab settings is prohibited post-experiment.
- Polymers are long molecules composed of repeating units.
- Group A is identified as an aldehyde group.
- The glycosidic linkage between glucose and galactose results in water and lactose.
