Chapter 8, Chemical Reactions, looks at the interaction of atoms and molecnles in chemical reactions. Chemical equations are balanced and organized into combination, decomposition, single replacement, double replacement, and combnstion reactions. Section 8.4, Functional Gronps and Reactions of Organic Componnds, and Section 8.5, Biochemical Compounds, are now Extended Topics, which classify compounds according to their strnctures to predict their properties and reactions.

Oily fish and extracted fish oils contain high concentrations of EPA and DHA. Fish oils also contain vitamins A and D. Oil derived from cod, halibut, or shark liver, or from fish body, typically contains about 200 mg/ml of long-chain omega-3 fatty acids. In addition, cod liver oil provides 50 pg/ml of vitamin A and 2 pg/ml of vitamin D. Many fish oil supplements are artificially enriched with omega-3 fatty acids. 

The fatty acids in vegetable oils are omega-6, in which the first double bond occurs at the sixth carbon, counting from the CH3 — end. However, the fatty acids in fish oils are mostly the omega-3 type, in which the first double bond occurs at the third carbon from the CH3— end.
