Study Notes
Understanding Biochemistry
- Biochemistry is the study of chemical processes within and related to living organisms.
- It merges biology and chemistry, focusing on the molecular mechanisms underpinning life.
Emergence of Biochemistry
- Biochemistry emerged as a distinct discipline in the late 19th century, gaining traction with the discovery of enzymes and biochemical pathways.
Main Focus
- The primary focus of biochemistry is to understand the structure, function, and interactions of biological molecules such as proteins, nucleic acids, lipids, and carbohydrates.
Importance of Biochemistry
- Studying biochemistry is crucial for advancing medical research, developing pharmaceuticals, and understanding metabolic disorders.
Factors Leading to Biochemistry's Emergence
- The increase in scientific knowledge, particularly in organic chemistry and the identification of biomolecules, facilitated the rise of biochemistry as a dedicated field.
Cell Composition
- Water typically constitutes about 70-90% of the weight of a typical cell, emphasizing its importance in cellular function and structure.
Dominant Chemical Component
- The predominant chemical component of living organisms is carbon, forming the backbone of organic molecules essential for life.
Role of Water as a Solvent
- Water acts as a biological solvent, facilitating biochemical reactions by dissolving various substances and enabling nutrient transport within cells.
Water's Buffing Properties
- Water's high specific heat capacity and ability to form hydrogen bonds contribute to its role as a buffer, regulating temperature and maintaining pH stability in biological systems.
Medium for Biochemical Reactions
- Biochemical reactions occur in aqueous environments, as water provides a suitable medium for the interaction of biological molecules.
