The total number of five-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.

Solution Summary: The author explains the structure of a lipid based upon the fused system of rings, known as the steroid nucleus.
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.

The number of microstates corresponding to each macrostate is given by N. The dominant macrostate or configuration of a system is the macrostate with the greatest weight W. Are both statements correct?
For the single step reaction: A + B → 2C + 25 kJ
If the activation energy for this reaction is 35.8 kJ, sketch an energy vs. reaction coordinate diagram for this reaction. Be sure to label the following on your diagram: each of the axes, reactant compounds and product compounds, enthalpy of reaction, activation energy of the forward reaction with the correct value, activation energy of the backwards reaction with the correct value and the transition state.
In the same sketch you drew, after the addition of a homogeneous catalyst, show how it would change the graph. Label any new line "catalyst" and label any new activation energy.
