Soap is an example of a fatty acid salt. Soap is usually made by mixing sodium or potassium salts, such as lye, with fatty acids. Soap also sometimes has air bubbles mixed in to decrease its density, enabling it to float on water.Continue Reading
Potassium fatty acid salts have a softer, creamier lather. The reaction between a fatty acid and a metal hydroxide forms a fatty acid salt and is called hydrolysis. This reaction occurs in two steps, with the oxygen-based ester bond of the fatty acid being broken down in the first step and the metal ion bonding in place of the oxygen atom in the second step.
The efficiency of reacting the fatty acid portion to become a fatty acid salt depends on the basicity and concentration of the metal hydroxide solution used. The type of fatty acid and the length of the alkyl chain it contains determine the property of the produced soap. Animal fats and tallow produce sodium stearate, a fatty acid salt possessing 18 carbon atoms. This soap is very hard and insoluble, as the longer the fatty acid chain gets, the more insoluble the soap becomes. Zinc stearate is a fatty acid salt used as a water-repellent for this reason.Learn more about Organic Chemistry
Each fat molecule is composed of one glycerol and three fatty acid molecules. These molecules are also known as lipids, and while they can provide essential nutrients, over-consumption of lipids can have adverse effects on a person's health, notes the University of Massachusetts.Full Answer >
Transfer hydrogenation of olive oil works by using a catalyst to help the reaction of the fats in olive oil with hydrogen gas, which bonds hydrogen atoms to available carbon atoms in the fatty acid chains to make them saturated. This results in a fat with a higher melting temperature.Full Answer >
Methionine is the amino acid that uses the abbreviation "met." The human body uses methionine to produce protein molecules that are then used to build muscle and organ tissues.Full Answer >
Gallic acid is a type of organic acid found in various fruits, herbs and other plants. This phenolic acid is commonly used for pharmaceutical purposes. Foods that include gallic acid include blueberries, walnuts and apples.Full Answer >
