Protein is the main macromolecule that is broken down in the stomach.

Carbohydrates.
no it is not... carbohydrates, lipids, proteins, and nucleic acids are the four main ones.
Carbohydrate
A molecule of chemical is generally referred to as organic if its main backbone constituent is composed of carbon atoms. In a stricter biological sense, organic would imply it was formed by some organism. ATP fits into both categories so yes, it is organic.
An organic molecule is any combination of atoms formed on a main base of Carbon, with most substituants made up of Hydrogen, Nitrogen, and Oxygen. A few examples would be methane, ethane, alcohols, DNA, there are many.
The esophagus is a muscular tube that connects the throat (pharynx) with the stomach. Its main function is to transport food and liquids from the mouth to the stomach through a process called peristalsis, which is a series of muscular contractions that push the contents downward.
Carbon is always the main component of organic molecules.
Organic molecules are substances found in living things, the four main classes are carbohydrates, proteins, lipids, and nucleic acids.The original definition of organic chemicals were ones that could only be made by living things (organisms, thus the name) never in a lab. Then chemists gradually learned how to make a few of them. The definition was changed to complicated compounds containing the element carbon. This usually requires a minimum of 2 carbon atoms per molecule. Now we can make many of them in industrial quantities. An organic molecule are built around chains of carbon atoms and are the molecules of life. The four main groups of organic molecules are proteins, nucleic acids, lipids, and carbohydrates.
The first macro molecule in our body is carbohydrates. Polysaccharides are made up simple sugars and are primary source of energy.The second macro molecule in our body is Polypeptide. Ex. proteins.The third macro molecule is fats. Ex. TriglyceridesThe fourth macro molecule is poly nucleotides. Ex. DNA
