Question

Relating to pharmacology:

What is pharmacodynamics? what is the relationship to osmosis? Ion charges? Lipids?

Answer 1

Ans) Pharmacodynamics: the branch of pharmacology concerned with the effects of drugs and the mechanism of their action.

- Osmosis results when two different concentrations of molecules are separated by a semi-permeable membrane. Molecules can move from areas of high concentration to low concentration. Some drugs can also be largely adsorbent and bind to many materials in the body. This is another type of physical action.

- An ion is a charged atom or molecule. It is charged because the number of electrons do not equal the number of protons in the atom or molecule. An atom can acquire a positive charge or a negative charge depending on whether the number of electrons in an atom is greater or less then the number of protons in the atom.

- Lipids are molecules that contain hydrocarbons and make up the building blocks of the structure and function of living cells. Examples of lipids include fats, oils, waxes, certain vitamins (such as A, D, E and K), hormones and most of the cell membrane that is not made up of protein.
