22 Μαρ 2021 · Fatty acids are carboxylic acids that are the structural components of many lipids. They may be saturated or unsaturated. Most fatty acids are unbranched and contain an even number of carbon atoms. Unsaturated fatty acids have lower melting points than saturated fatty acids containing the same number of carbon atoms.

Types of fatty acids. Comparison of the trans isomer elaidic acid (top) and the cis isomer oleic acid (bottom) Fatty acids are classified in many ways: by length, by saturation vs unsaturation, by even vs odd carbon content, and by linear vs branched.
(A) This is the structure of stearic acid, an 18-carbon saturated fatty acid. The normal numbering system, starting with the carboxylic acid, is shown in blue. The carbons and oxygens...
(Top) Stearic acid is a fully saturated fatty acid with no carbon-carbon double bonds. (Bottom) Oleic acid is an unsaturated fatty acid. Due to the mechanism of synthesis, most fatty acids have an even number of carbons, although odd-numbered carbon chains can also be generated.
15 Ιαν 2021 · Stearic acid is an example of a saturated fatty acid (Figure \(\PageIndex{1}\)). When the hydrocarbon chain contains a double bond, there are less hydrogens attached to the carbon skeleton and the fatty acid is said to be unsaturated.
23 Αυγ 2021 · Stearic acid, a saturated fatty acid, by contrast has a straight hydrocarbon tail. Figures 2.190-2.194 show the most common saturated and unsaturated fatty acids. Fatty acids with unsaturated tails have a lower melting temperature than those with saturated tails of the same length.
31 Ιαν 2024 · Two examples of the same 18 carbon saturated fatty acid (stearic acid/stearate) are shown in Figures \(\PageIndex{1}\) and \(\PageIndex{3}\). Figure \(\PageIndex{3}\) is the simplified view of this fatty acid.
