The total number of six-membered rings that are present in the structure of a cholesterol molecule has to be stated. Concept introduction: The structure of the lipid that is based upon the fused system of rings which includes three identical six-membered rings and only one five-membered ring is known as steroid. The fused ring system of the steroid is known as the steroid nucleus. A steroid of C 27 molecule which is a unit of cell membrane and also a precursor of another steroid-based lipid is known as cholesterol.

Definition Definition Group of atoms that shape the chemical characteristics of a molecule. The behavior of a functional group is uniform in undergoing comparable chemical reactions, regardless of the other constituents of the molecule. Functional groups aid in the classification and anticipation of reactivity of organic molecules.

Laser. Indicate the relationship between metastable state and stimulated emission.
The table includes macrostates characterized by 4 energy levels (&) that are
equally spaced but with different degrees of occupation.
a) Calculate the energy of all the macrostates (in joules). See if they all have
the same energy and number of particles.
b) Calculate the macrostate that is most likely to exist. For this macrostate,
show that the population of the levels is consistent with the Boltzmann
distribution.
