Study Notes
Biochemistry
- Biochemistry examines the chemical reactions within biological molecules.
- Metabolism encompasses all biochemical reactions in an organism.
- A limited set of molecules (e.g., 20 amino acids for proteins) simplifies metabolic control.
- Molecular structure is closely linked to function.
Building Blocks of Life
- Hydrogen, carbon, oxygen, and nitrogen are the four most abundant elements in living organisms, comprising over 99% of atoms.
- Carbon's ability to form long chains and ring structures makes it crucial for building organic molecules.
- Organic molecules consist of carbon skeletons with other atoms attached, determining their function.
- A period of chemical evolution likely preceded life, where simple carbon-based molecules formed from even simpler ones.
- Simple biological molecules act as building blocks for larger, complex molecules.
