an intermediate switch is a switch of 4 terminals which is used to control devices from more than 2 locations if you want to control a device eg lamp from one locati on you use a normal switch you could see two terminals behind it
Fatty acids are made from carbon, hydrogen and oxygen. Fatty acids are constructed from the chemical elements carbon, oxygen and hydrogen. Fatty acids can be divided into a carboxylic acid head groupâhence fatty acidâlinked to a long chain of carbon atoms. The bond between the carbon atoms stores a large amount of biochemical energy and is very stable, allowing fats to be an efficient long-term store of energy in your body.
There are three main types of fatty acids: saturated, monounsaturated and polyunsaturated. All fatty acids are chains of carbon atoms with hydrogen atoms attached to the carbon atoms. A saturated fatty acid has the maximum possible number of hydrogen atoms attached to every carbon atom.n foods of animal origin, a large proportion of fatty acids are saturated. In contrast, in foods of plant origin and some seafood, a large proportion of the fatty acids are monounsaturated and polyunsaturated.
