Whether cortisol is a naturally occurring steroid hormone or a synthetic analog of such has to be predicted. Concept introduction: The families of lipids that have messenger functions are called steroid hormones. It is basically a hormone that is a cholesterol derivative. There are two classes of steroid hormones, sex hormones and adrenocorticoid hormones.

Solution Summary: The author explains that cortisol is a naturally occurring steroid hormone, and that progesterone is an inflammatory hormone.
Chemical pathways by which living things function, especially those that provide cellular energy, such as the transformation of energy from food into the energy of ATP. Metabolism also focuses on chemical pathways involving the synthesis of new biomolecules and the elimination of waste.

Bicarbonate is crucial for the control of body pH (for example, blood pH:
7.4). A more self-indulgent use is in baking soda, where it serves as a
source of CO2 CO₂ 2 gas, which gives bread and pastry their fluffy
constituency.
(i) Draw at least one additional resonance form.

(ii) Using curved "electron-pushing" arrows, show how these Lewis structures may
be interconverted by movement of electron pairs. (iii) Determine which form or
forms will be the major contributor(s) to the real structure of bicarbonate,
explaining your answer on the basis of the criteria in Section 1-5.
