    Study Notes

    Definition

    • A biomolecule is a type of molecule that is present in living organisms
    • Biomolecules are the building blocks of life and perform a wide range of functions necessary for life

    Types of Biomolecules

    • Carbohydrates: provide energy and structure for cells
      • Examples: sugars, starches, cellulose
    • Proteins: perform a wide range of functions, including enzymatic, structural, and transport roles
      • Examples: enzymes, hormones, collagen
    • Lipids: provide energy and structure for cells
      • Examples: fats, oils, cholesterol
    • Nucleic Acids: contain genetic information and transmit it from one generation to the next
      • Examples: DNA, RNA
    • Amino Acids: building blocks of proteins
      • Examples: glycine, alanine, serine

    Functions of Biomolecules

    • Energy production and storage: carbohydrates, lipids, and proteins provide energy for cells
    • Structural roles: proteins, carbohydrates, and lipids provide structure and support for cells
    • Regulatory roles: proteins, hormones, and neurotransmitters regulate cellular processes
    • Transport roles: proteins and lipids transport molecules and ions across cell membranes
    • Information storage and transmission: nucleic acids contain genetic information and transmit it from one generation to the next
