what is the chemical composition of a fart?

Gases are also what can make farts smell bad. Tiny amounts of hydrogen, carbon dioxide, and methane combine with hydrogen sulfide (say: SUHL-fyde) and ammonia (say: uh-MOW-nyuh) in the large intestine to give gas its smell.

Intestinal gas is produced within the body when bacteria in the colon break down food. This is called endogenous gas. Endogenous gas consists mainly of hydrogen and, for some people, methane. It can also contain small amounts of other gases, such as hydrogen sulfide, which make farts smell bad.

In contrast, open-loop systems emit hydrogen sulfide, carbon dioxide, ammonia, methane, and boron. Hydrogen sulfide, which has a distinctive “rotten egg” smell, is the most common emission [5]. Once in the atmosphere, hydrogen sulfide changes into sulfur dioxide (SO2).

Chemically, kerosene is a mixture of hydrocarbons. The chemical composition depends on its source, but it usually consists of about 10 different hydrocarbons, each containing 10 to 16 carbon atoms per molecule.

['Aerosols, such as air freshener, deodorant, fabric protector, hair spray, vegetable oil spray, and spray paint.', 'Gases, such as butane (lighter fluid), computer cleaning spray, freon, helium, nitrous oxide (laughing gas), which is found in whipped cream containers, and propane.']

Typical Composition of Natural Gas In its purest form, such as the natural gas that is delivered to your home, it is almost pure methane. Methane is a molecule made up of one carbon atom and four hydrogen atoms, and is referred to as CH4.

Bacteria breaks down organic components inside our stomachs into hydrogen sulphide (H2S), which gives the infamous 'rotten eggs smell'. For us, this meant that we needed to detect trace amounts of hydrogen sulphide. A fart contains from 0.001 PPM to 1 PPM of H2S (indeed, the human nose is very sensitive).

LPG gas is basically propane and butane, and it is odorless in its natural state. The smell that you notice when there is a leak is actually from an entirely different agent called Ethyl Mercaptan. This substance is added to the gas when it leaves the main storage terminals.

Natural gas is odorless, but an additive called mercaptan is included to alert people of leaks. Mercaptan has a highly recognizable, sulfur-like, "rotten egg" odor used to help people detect a leak.

Beer makes your farts smellier because of the sulfate in it. Sulfur-containing chemicals can be found in DMS, malt, yeast and even hops. Obviously drinking involves swallowing air that has to come out eventually too. Drinking beer releases carbon dioxide gas which builds up in your gut.

Tiny amounts of hydrogen, carbon dioxide, and methane combine with hydrogen sulfide (say: SUHL-fyde) and ammonia (say: uh-MOW-nyuh) in the large intestine to give gas its smell. Phew!

These farts are made up mostly of hydrogen and methane, which come from bacteria in the colon feasting on the parts of our meals we aren't able to digest ourselves—like lactose in milk, or complex carbohydrates found in beans and legumes.

In its purest state, natural gas is odorless, colorless and tasteless. A harmless chemical (the most common is mercaptan) is added to natural gas to make it smell and easier to detect. Gasoline on the other hand smell due to the presence of hydrocarbon called benzene.

If you're wondering why we'd even ask such a question, in November 2015, the internet erupted (pun intended) when Google returned an affirmative search result to those who asked, “Does farting burn calories?” The search engine responded with the claim that a single fart burns approximately 67 calories, and that farting ...
