Protein

Protein is an important nutrient that gives the body energy. They are important building blocks for the body, and are needed for maintenance. Muscles, skin, tendons, and hair are all made up of proteins. They also have many other functions, like breaking down different things in the body, transporting oxygen, and fighting off bacteria. They make chemical reactions work like they should, and are therefore important "tools" for all cells and organisms. Proteins like Hemoglobin are important for carrying oxygen through your blood. Enzymes are proteins which causes chemical reactions in the cells. Foods like meat, eggs, seafood and beans highly consist of proteins. It is recommended to get about 56 - 91g of protein for the average male, and 46 - 75g for the average female. However, there are many factors for each individual person that would change this number. If the body does not get enough proteins, it will negatively affect health and body composition. Proteins are therfore extremely important for the body and can be found in all cells and living organisms.

Proteins are build up of long chains of aminoacids attached to one another in a particular order. The structure of the proteinmolecules all depend on the order of the aminoacids:
