Page 1: Fundamentals of Biochemistry
The page introduces core concepts of biochemistry, explaining how living things depend on chemical processes and the interplay of fundamental elements. It covers atomic structure, molecular interactions, and major biomolecule categories.
Definition: Biochemistry is the study of chemical compositions and reactions occurring within living organisms.
Highlight: Of the 100 chemical elements, only a small subset including Carbon, Nitrogen, Oxygen, and Hydrogen are crucial for life processes.
Example: Water (H₂O) demonstrates how different elements combine to form compounds essential for life.
Vocabulary:
- Substrate: The molecule upon which an enzyme acts
- Catalyst: A substance that speeds up chemical reactions without being consumed
- Monomer: Single unit of a larger molecule
- Polymer: Multiple monomers linked together
Quote: "Water acts as a universal solvent due to its polar nature and ability to form hydrogen bonds."
The page details various biomolecules:
- Carbohydrates (C,H,O in 1:2:1 ratio)
- Lipids
- Proteins (composed of CHON)
- Nucleic acids (containing C,H,O,N,P)
It also explains enzyme function through the lock-and-key model and illustrates how catalysts reduce activation energy in chemical reactions, demonstrating the efficiency of biochemical processes in living systems.
