The two hydrogen atoms (H) that are bound to the doubly-bonded carbon atoms (C) can occur in a cis or trans configuration. fatty mcblog A cis configuration means that the two fatty mcblog hydrogen atoms are on the same side of the chain. Because of the polarization of the hydrogen fatty mcblog atoms, the hydrogen 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. |

| The term "saturated" refers to hydrogen, fatty fuck in that all carbons (apart from the carboxylic acid [-COOH] group) contain as many hydrogens as possible. In other words, the omega (ω) end contains 3 hydrogens (CH3-) and each carbon within the fatty fuck chain contains 2 hydrogens (-CH2-). Saturated fatty acids form straight chains and, as a result, can be packed together very tightly, allowing living fatty fuck organisms 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 This is a computer generated image of Dodecanoic Acid, a fatty acid. |
