Where is armpit, foot rot, bad breath?

Some people unfortunately have body odor that is uncomfortable for people around them, described as armpit, foot rot or bad breath. This is due to the incredible combination of different chemicals.

A British level 2 chemistry teacher has created a graphic design board to show the chemical compounds and the characteristic smells they cause in the armpits, mouth, legs and even when the subject is flat. .

As we all know, in most cases, bad breath or bad breath is the product of bacteria in the mouth when they produce waste products and chemical compounds. However, many people do not know that the "culprits" are the volatile sulfur compounds , including hydrogen sulfide that smells rotten eggs, methanethiol like sour cabbage and slightly dim garlic garlic.

At low levels, these compounds are difficult to detect with the human nose. Certain foods and beverages can make the problem more serious, or at least easier to detect.

In addition to the three main "culprits" above, the compound called 3-mercapto-3-methylbutylformate is produced when someone drinks coffee that causes his / her breath to smell bad. Garlic is caused by allyl methyl sulfide - a product of garlic decomposition.

Meanwhile, eating meat with fish can make our breath smell like rotting corpses. This is because bacteria that produce volatile sulfide compounds rely on proteins and produce additional compounds such as cadaverine or putrescine, which smell like fish or decaying bodies.

Previous research has shown that sulfide-containing organic compounds are produced in the digestive system and cause flatulence. Hydrogen sulphide, methanethiol and dimetila sulfide are once again the key "culprits" that create a rotten smell when the owner is flat.

Statistics show that there are nearly 1 million bacteria in each cm2 on your armpits and they can cause bad smell if not bathed or washed. There are two sulfur-free compounds that are the culprit in the underarm area: 3-methyl-2-hexenoic acid, characterized by an unpleasant perspiration smell and described by some experts as "goat smell" , and 3-hydroxy-3-methylhexanoic acid produces the smell of the spoon. Another compound called 3-methyl-3-sulfanylhexan-1-ol along with other sulfide compounds leads to an onion-like odor.

Just like with the armpits, the persistence of sweat provides a favorable environment for bacteria to proliferate, proliferate and produce toxic compounds in the legs. 2 key factors leading to smelly feet are propanoic acid and isovaleric acid. In it, propanoic acid is described as "pungent, sour and rancid", while isovaleric acid smells "rancid and fermented".
