At first carbohydrates, fats and proteins are catabolized by separate pathway to form acetyl-coA then Acetyl-coA enters into Citric acid cycle. Carboxylic acids contain the carboxylic acid functional group (the -COOH group) linked to a hydrocarbon chain. It is widely used as a flavoring agent, preservative, and cleaning agent. For example, Oranges, tomatoes, and Lemon contain the highest amount of citric acid. Most carboxylic acids have trivial names, many of which are related to their origin in nature—for example, formic, malic, valeric, and citric acids. Methane thus gives rise to methanoic acid, HCOOH, which is more widely known by its trivial name formic acid, while ethane gives rise to ethanoic acid, which is much more commonly called acetic acid.
