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.
Fats can be saturated or unsaturated, depending on how many hydrogen atoms link to each carbon in their chemical chains. The more hydrogens attached to the chain, the more saturated the fat will be. If there are hydrogen atoms missing, the fatty acid is considered unsaturated. Saturated Fats Saturated Fats are fatty acids that have hydrogens at all the points on their chemical chain.
