Study Notes
Protein Structure and Function
- Proteins are fundamental structural components of the cytoskeleton.
- Proteins serve as enzymes, crucial biochemical catalysts.
- Immunoglobulins are proteins that act as a primary defense against pathogens like bacteria and viruses.
- Many hormones are composed of proteins.
- Actin and myosin, examples of structural proteins, enable muscle fiber contraction and movement.
- Some proteins act as receptors found in cellular membranes, cytoplasm, and nucleus.
- Transport proteins facilitate the movement of specific substances across membranes or within bodily fluids.
- Storage proteins bind and store specific substances like iron (stored as ferritin).
- Respiratory pigments like cytochromes, hemoglobin, and myoglobin, as well as components of the electron transport chain, are protein-based.
- Proteins can be broken down for energy production under certain conditions.
- Proteins play a role in maintaining electrolyte and water balance by contributing to osmotic pressure.
