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.
These names describe the structure of the fatty acid in terms of whether it is fully loaded with hydrogen. Fatty acids also differ in the length of the carbon chain. Short-chain fatty acids have less than eight carbons. Medium-chain fatty acids have 8 to 14 carbons and long-chain fatty acids have 16 or more carbons.nsaturated Fatty Acids: These are called unsaturated because they have lost one or more pairs of hydrogens from their carbon chain. Unsaturated fatty acids include mono-and polyunsaturated fatty acids (PUFAs). When hydrogen pairs are removed, the fatty acid molecule develops a kink or bend, known as a double bond.
