The two hydrogen atoms (H) that are bound hepatitis to the doubly-bonded carbon atoms (C) can occur in a cis or trans configuration. A cis configuration means that the two hydrogen atoms are on the same side of the chain. Because of hepatitis the polarization of the hydrogen atoms, the hydrogen hepatitis atoms repel each other and cause the chain to bend. The more double-bonds the chain has in the cis configuration, the more bent it is. When a chain has many cis bonds, it becomes quite curved. For example, oleic acid, with one double bond, has a "kink" in it, while linoleic acid, with two double bonds, has a more pronounced bend. Linolenic acid, with three double bonds, forms a hooked shape. A trans configuration, by contrast, means that the two hydrogen atoms occur on opposite sides of the chain. As a result, they don't cause the chain to bend much, and their shape is similar to the straight saturated fatty acids. |

| Reduction of fatty acids yields diets special conditions fatty alcohols. Types of fatty acids Several fatty acid molecules Saturated fatty acids Saturated fatty acids do not contain any double bonds or other functional groups along the chain. The term "saturated" refers to hydrogen, in that all carbons (apart from the carboxylic acid [-COOH] group) contain as many hydrogens as possible. In diets special conditions other words, the omega (ω) end contains 3 hydrogens (CH3-) and each carbon within the chain contains 2 hydrogens (-CH2-). Saturated fatty acids form straight chains and, as a result, can be packed together very tightly, allowing living organisms diets special conditions to store chemical energy very densly. The fatty tissues of animals contain large amounts of long-chain saturated fatty acids. In IUPAC nomenclature, fatty acids have an -oic acid suffix. In common nomenclature, the suffix is usually -ic. Some saturated fatty acids are: Acetic: CH3COOH Butyric: CH3(CH2)2COOH Lauric (dodecanoic acid): CH3(CH2)10COOH Myristic (tetradecanoic acid): CH3(CH2)12COOH Palmitic (hexadecanoic acid): CH3(CH2)14COOH Stearic (octadecanoic acid): CH3(CH2)16COOH Arachidic (eicosanoic acid): CH3(CH2)18COOH Unsaturated fatty acids Unsaturated fatty acids are of similar form, except that one or more alkene functional groups exist along the chain, with each alkene substituting a singly-bonded " -CH2-CH2-" part of the chain with a doubly-bonded "-CH=CH-" |
