Study Notes
Phosphorus Overview
- Atomic symbol is P, atomic number is 15, and atomic mass is 30.
- Makes up approximately 1.2% of the human body.
Role in Living Organisms
- Essential component of DNA and RNA structures.
- Integral to the formation of bones and teeth as calcium phosphate.
Earth Composition
- Comprises 0.12% of the Earth's crust.
- Ranked as the 11th most abundant element on Earth.
Applications Beyond Biology
- Serves as a crucial nutrient for plants; primarily found in phosphate compounds for fertilizer production.
- Utilized in manufacturing safety matches, pyrotechnics, and incendiary shells.
Physical Properties
- Classified as a non-metal with a solid state at room temperature.
- Appears silvery-white or red, depending on its bonding form.
Biological Processes
- Involved in the phosphorus cycle, which describes its movement through lithosphere, hydrosphere, and biosphere.
- Unlike other cycles, the atmosphere has minimal involvement in the phosphorus cycle.
Biological Molecule Composition
- Found in larger biological molecules such as ATP (adenosine triphosphate), ADP (adenosine diphosphate), and DNA.
Relation to Biological Processes
- Categorized as a nucleic acid; phosphate groups form the backbone of the DNA structure.
- Phosphate groups consist of one phosphorus atom bonded to four oxygen atoms, crucial in nucleotide structure and DNA integrity.
