Such groups of natural compounds also include widespread in flora phenolic acids, oxidized and reduced flavonoids and their glycosides (Brown, et al., 2012). When reading the “Carbonic Acids (mono- and dibasic) series of saturated and unsaturated, oxy- and oxoacids” module within the course of “Organic chemistry” the questions connected to the classification, nomenclature, reaction ability of these compounds, caused by the existence of carboxyl group, and also features of dibasic acids, oxy- and oxoacids, caused by the mutual influence of functional groups are considered. The questions listed above are further studied in such courses, as bioorganic chemistry, biochemistry and other. Neutral lipids (solid fats and oils) represent esters of the higher carbonic acids and glycerin (triglycerides) and, therefore, questions of the mechanism of formation of ester bond and its hydrolysis, structure and properties of esters, unsaturated higher carboxylic acids are basic for understanding of physiological action of lipids and the role of polyene acids (Toriyama-Baba, et al., 2001).
