Study Notes
Protein Composition and Structure
- A monomeric protein is composed of a single polypeptide chain.
Etymology of Proteins
- The Greek word 'proteios' means 'of the first rank' or 'primary'.
Oligomeric Proteins
- A dimeric protein is composed of two polypeptide chains, whereas a tetrameric protein is composed of four polypeptide chains.
Cellular Importance of Proteins
- Proteins constitute about 10-15% of the cellular dry weight.
Cellular Distribution of Proteins
- Proteins occur throughout the cell, but their distribution varies depending on the cell type and function.
