Study Notes
Macromolecules
- Building blocks of macromolecules are known as monomers.
Biological Processes
- The process of adding water to split larger molecules is called hydrolysis.
- Dehydration synthesis describes the creation of larger molecules from smaller subunits.
Enzymes
- Enzymes are primarily composed of proteins.
- When enzymes denature, they lose their functional shape, which impairs their catalytic activity.
Specific Enzymes and Substrates
- The substrate for the enzyme amylase is starch.
Chemical Indicators
- Iodine indicator turns deep blue in the presence of starch.
- Benedict’s Reagent changes color in the presence of reducing sugars, typically resulting in a color change from blue to green, yellow, or red, indicating the presence of sugars.
Optimal Conditions
- Amylase functions optimally at a pH of around 7 (neutral).
Lipid Hydrolysis
- The enzyme that catalyzes the hydrolysis of lipids is known as lipase.
