Study Notes
Isomers and Isotopes
- Isomers possess the same molecular formula but differ in structural arrangement.
- Isotopes have the same number of protons but vary in neutron count, resulting in different atomic masses.
Hydrolysis and Dehydration
- Hydrolysis entails breaking down compounds by adding water, a crucial process in digestion.
- Dehydration involves the removal of water molecules, facilitating the formation of larger compounds.
Functions of Carbohydrates
- Serve as a primary energy source for all cellular activities.
- Contribute to structural integrity by building plant cell walls.
- Form part of the exoskeletons in arthropods, providing support and protection.
Functions of Lipids
- Energy storage: burning 1 gram of lipid yields 9 calories of heat.
- Structural role: integral to phospholipids, key components of cell membranes.
- Endocrine functions: lipids are precursors to hormone synthesis.
- Provide protection for internal organs and act as heat insulators.
Characteristics of Fats
- Predominantly found in animal sources.
- Saturated fatty acids are commonly present, which are solid at room temperature, indicating higher hydrogen saturation.
