Study Notes
Biochemistry Overview
- Biochemistry merges life sciences and chemical sciences, studying the biochemical processes within living organisms.
- It serves as a branch of chemistry focused on the chemical compositions and reactions fundamental to life.
Cells
- Cells are the fundamental units of life, characterized by their organization and ability to generate energy.
- Life processes are maintained through chemical reactions that alter substances to form new compounds.
Biological Macromolecules
- Four primary categories of biological macromolecules: carbohydrates (CHO), proteins, lipids, and nucleic acids.
Proteins and Amino Acids
- Dietary proteins are digested and broken down into amino acids, which serve as the essential building blocks of life.
Lipids
- Lipids derive from the Greek word "lipos," which translates to fats; they play vital roles in cellular structure and energy storage.
Nucleic Acids
- Nucleic acids, including DNA, are crucial macromolecules responsible for genetic information and heredity.
Atoms and Molecules
- Atoms are the smallest units of matter; they form molecules when bonded together.
- Molecular formation progresses as atoms combine to create molecules, which then organize into cells.
Types of Cells
-
Prokaryotic Cells:
- Unicellular organisms, consisting of single cells.
- Examples include bacteria, plants, and fungi.
-
Eukaryotic Cells:
- Multicellular organisms that require more than one cell to function properly.
- Includes complex organisms such as humans and certain types of cancer cells.
