Study Notes
Cellular Components
- The main components of cells are Carbon, Hydrogen, Oxygen, Nitrogen, Phosphorus, and Sulfur.
- Carbon is the backbone of all molecules in carbon-based lifeforms.
Hydrophilic and Hydrophobic
- Hydrophilic refers to molecules that are attracted to water.
- Hydrophobic molecules are 'water-hating' and do not mix with water.
Phosphorus
- Phosphorus is an essential element in cells, playing a crucial role in energy storage and transfer.
- The primary function of Phosphorus is to facilitate energy storage and transfer in cells.
Sulfur
- Sulfur is involved in the formation of disulfide bonds, which are crucial for protein structure and function.
- The primary role of Sulfur in cells is to facilitate the formation of disulfide bonds in proteins.
Oxygen and Hydrogen
- Oxygen is a part of water and is involved in hydrogen bonding.
- Hydrogen is also a part of water and is involved in hydrogen bonding.
