Proteins
  • the most abundant organic molecules in cells
  • most genetic informationare expressed by proteins
    1. Enzymes are catalysts that speed the rate of chemical reactions. Its suffix is -ase
    2. Hormones are chemical messengers secreted by endocrine glands. They also regulate other parts of the body.
    3. Antibody is globular protein that is made by the body to response to presence of a foreign or harmful molecule called antigen
    4. Amino Acid are building blocks of proteins (monomers that make up the polymr protein)
      3 types of Proteins:
      • Structural Proteins: important in maintaining the shape of the cells and organism.
      • Regulatory Proteins: determine which activities will occur in the organisms
      • Carrier Protein: pick and deliver molecules at one place and transport them to another place.
    Proteins plays an important aspect in helping stimulate the proper body functions plus giving proper energy for our body to perform work well.
