Even those fatty acids that are insoluble in water will dissolve in warm ethanol, and can be titrated with sodium hydroxide solution using phenolphthalein as an indicator to a pale pink endpoint. This analysis is used to determine the plump tgp free plump tgp fatty acid content of fats, i.e. the proportion of the triglycerides that have been hydrolyzed. Autoxidation plump tgp and rancidity See also: Rancidification Fatty acids at room temperature undergo a chemical change known as autoxidation. The fatty acid breaks down into hydrocarbons, ketones, aldehydes, and smaller amounts of epoxides and alcohols. Heavy metals present at low levels in fats and oils promote autoxidation. Fats and oils often are treated with chelating agents such as citric acid. |

| Free fatty acids are an important source of fuel for many tissues since they can yield relatively large quantities of ATP. Many cell types atp can use either glucose or fatty acids for this purpose. However, heart and skeletal muscle prefer fatty acids. On the other hand, the brain cannot use fatty acids as a source of fuel, relying instead on glucose, or on ketone bodies produced by the liver from fatty acid metabolism during starvation, or atp periods of low carbohydrate intake. pH Formic acid atp and Acetic acid are totally soluble in water and dissociate to form reasonably strong acids (pKa respectively 3.77 and 4.76). Longer chain fatty acids do not show a great change in pKa: Nonanic acid, for example, has a pKa of 4.96. However, as the chain length increases the solubility of the fatty acids decreases very rapidly, so that the longer chain fatty acids have very little effect on the pH of a solution. |
