    Study Notes

    Biochemistry Overview

    • Biochemistry primarily studies the chemical processes and substances that occur within living organisms.

    Biomolecules and Their Importance

    • Biomolecules are essential for the structure, function, and regulation of living organisms.
    • They play a crucial role in various cellular processes, including metabolism, growth, and response to stimuli.

    Biochemical Laboratory Tests

    • Biochemical laboratory tests are used to diagnose and monitor diseases, such as diabetes, by measuring the levels of certain biomolecules in the body.

    Nucleic Acids

    • DNA (deoxyribonucleic acid) is responsible for the storage and transmission of genetic information.

    Hydrogen Bonds

    • Hydrogen bonds are formed by the sharing of a hydrogen between two electron donors.

    Metabolic Pathways

    • Anabolic pathways consume energy to build complicated molecules from simpler compounds, such as proteins, glycogen, and lipids.
    • Examples of anabolic pathways include protein synthesis and glycogen synthesis.

    Metabolism

    • The sum total of the chemical activities of all cells is called metabolism.
    • Metabolism involves the breakdown of food and transportation of nutrients to tissues, as well as the synthesis of new molecules.

    Cellular Compartmentalization

    • The cell membrane prevents interference of metabolic reactions within the cell by compartmentalizing specific reactions.

    Citrate Cycle and Respiratory Chain

    • The citrate cycle (also known as the Krebs cycle or tricarboxylic acid cycle) and respiratory chain are involved in the breakdown of acetyl-CoA and the generation of ATP during cellular respiration.

    Hydrophobic Interactions

    • Hydrophobic interactions are formed by the interaction between nonpolar hydrophobic side chains by eliminating water molecules.

    Catabolic Reactions

    • Catabolic reactions release energy by breaking down complex molecules into simpler compounds, such as glycolysis.

    Enzymes

    • Enzymes are biological molecules that catalyze biochemical reactions in the body.

    Enzyme Regulation

    • The activity of enzymes is influenced by factors such as temperature and pH, which can alter the enzyme's shape and activity.

    Van der Waals Forces

    • Van der Waals forces are weak forces of attraction between all atoms, due to oscillating dipoles.
