    Study Notes

    Chemical Elements and Molecules

    • A molecule is formed by the chemical bonding of two or more elements.
    • Compounds consist of different elements bonded together; pure molecules do not qualify as compounds if they consist of the same type of element.

    Energy in Chemical Reactions

    • Reactions can be classified as endergonic (energy absorbed) or exergonic (energy released).
    • Exergonic reactions release energy, while endergonic reactions require an input of energy to proceed.

    Enzymes and Metabolic Processes

    • Enzymes act as catalysts to speed up chemical reactions in metabolic processes.
    • Metabolism consists of two main processes: anabolic (building complex molecules) and catabolic (breaking down molecules).

    Organic Compounds

    • Organic compounds typically contain carbon atoms bonded by covalent bonds.
    • These compounds can be complex and flexible in structure, due to the nature of carbon bonds.

    Examples of Nutrients

    • Tryptophan is an amino acid found in foods such as turkey and is crucial for various biological functions.
    • Amino groups play an essential role in the formation of proteins and other biological molecules.

    Synthesis and Recycling in the Body

    • The body synthesizes compounds through metabolic pathways and recycles materials to maintain physiological functions.
    • Understanding the role of various organic compounds and molecules is vital for comprehending biological processes.
