    About the Lecture

    The lecture Role of Water – Biological Interactions by Adam Le Gresley, PhD is from the course Medical Chemistry.


    Included Quiz Questions

    1. The essential electronic and steric features responsible for a drugs activity
    2. The principle site of interaction with a drug on an enzyme
    3. The molecular model of an active site on a protein
    4. A structure designed to reduce unwanted non-active metabolic side products
    5. None of the above
    1. The formation of water shells around each molecule of compound prevents their interactions with each other and enables them to achieve the lowest energy configuration
    2. The formation of water shells around each molecule of compound prevents their interactions with each other and allows them to reach the highest energy configuration
    3. The formation of water shells around each molecule of compound helps their interactions with each other and allows them to reach the highest energy configuration
    4. The formation of compound molecule shells around each water molecule prevents their interactions with each other and allows them to gain the lowest energy configuration
    5. The formation of compound molecule shells around each water molecule helps their interactions with each other and allows them to gain the maximum energy configuration
    1. Directly related to the number and strength of the bonds
    2. Indirectly related to the number and strength of the bonds
    3. Directly related to the strength of bonds, but inversely proportional to the number of bonds
    4. Independent of the number and strength of bonds
    5. Directly related to the number of bonds, but inversely proportional to the bond strengths
    1. Becomes more disordered
    2. Becomes more ordered
    3. Remained unaffected
    4. Gives a highly disordered pattern with evenly distributed patches of ordered symmetry
    5. Gives a highly ordered pattern with evenly distributed patches of disordered symmetry
    1. The energy of the system drops down
    2. The energy of the system shoots up
    3. The water molecules get condensed around the drug-receptor complex
    4. The water molecules facilitate the hydrogen bonding between the drug and receptor molecules
    5. The water molecules provide hydrophilic nature to the drug molecule
