Protein is the main macromolecule that is broken down in the stomach.
Carbohydrates are the organic molecules that provide the most energy and are easily digested by the body. Glucose, a simple carbohydrate, is the main source of energy for our cells.

In the stomach, primarily proteins are being digested. The stomach secretes enzymes like pepsin and hydrochloric acid that break down proteins into smaller peptides and amino acids. Lipids and carbohydrates also undergo some digestion in the stomach, but protein digestion is the main focus.
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.
The pyloric pump is a muscular valve located between the stomach and the small intestine, specifically at the junction of the pylorus of the stomach and the duodenum of the small intestine. Its main function is to regulate the flow of partially digested food from the stomach into the small intestine. The pyloric pump contracts and relaxes to control the release of chyme (partially digested food) into the small intestine for further digestion and absorption. Dysfunction of the pyloric pump can lead to issues such as gastroparesis or delayed gastric emptying.
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.
Starch is an organic compound because it is made up of carbon, hydrogen, and oxygen atoms. It is a polysaccharide, which is a type of carbohydrate that is found in plants and serves as their main energy storage molecule.
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.
