In chemistry, particularly in biochemistry, a fatty acid is a carboxylic acid with an aliphatic chain, which is either saturated or unsaturated. Most naturally occurring fatty acids have an unbranched chain of an even number of carbon atoms, from 4 to 28. [1]
Introduction to Fatty Acids. Fatty acids are merely carboxylic acids with long hydrocarbon chains. The hydrocarbon chain length may vary from 10-30 carbons (most usual is 12-18). The non-polar hydrocarbon alkane chain is an important counter balance to the polar acid functional group.
Jan 23, 2023 · Acid or base-catalyzed hydrolysis yields the component fatty acid, some examples of which are given in the following table, together with the alcohol component of the lipid. These long-chain carboxylic acids are generally referred to by their common names, which in most cases reflect their sources.
Mar 22, 2021 · Table 17.1.1 lists some common fatty acids and one important source for each. The atoms or groups around the double bonds in unsaturated fatty acids can be arranged in either the cis or trans isomeric form. Naturally occurring fatty acids are generally in the cis configuration.
Oct 3, 2021 · The capability of investigating and distinguishing fatty acids and their metal soaps through their rich infrared features, such as the acidic carbonyl, the carboxylate shifts, the variable splits of alkyl chain stretching, bending, twisting, wagging, and rocking vibrations, as well as the hydroxyl peak envelopes and acid dimer bands, allows for ...

PURITY TESTS. Unsaponifiable matter is the whole of the products present in a fatty substance which, after saponification thereof with an alkaline hydroxide and extraction by a specified solvent, remains non-volatile under defined conditions of the test.

There are two main types of omega-3 fats that have essential roles in human health: EPA and DHA: Eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) come mainly from cold-water fish, so they are sometimes called marine omega-3s. Salmon, mackerel, tuna, herring, and sardines contain high amounts of EPA/DHA.
