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.
A fatty acids is specifically a carboxylic acid (COOH) on the end of a long chain of carbons, which can be saturated (all carbon-carbon single bonds, which means the carbons are also bonded to hydrogen atoms), or unsaturated (some carbon-carbon bonds may be double).They can be thought of as a building block for lipids.est Answer: Fatty acids are merely carboxylic acids with long hydrocarbon chains. The hydrocarbon chain length may vary from 10-30 carbons (most usual is 12-18).
