Scientists uncover the mysteries of protein and its key role in the body

When it comes to proteins, many people will say that they are an important component of all cells and tissues in the body, and that all important components of the body need to be involved in proteins.
this article, researcher Professor Nathan Ahlgren, from Clark University, explains what proteins are, how they are formed, and what important functions proteins play in the body.
is protein? Protein is the basic structure of all life, of course, it is a molecule, the key to protein is that it is composed of smaller components, these components are amino acids, we can think of amino acids as a string of different colors of beads, each bead represents an amino acid, and amino acids are made up of smaller molecules, which contain carbon, oxygen, hydrogen, and sometimes sulfur atoms.
So proteins are essentially a string of these small amino acids, and we can combine 22 different amino acids in any different combination to produce different proteins.
protein usually does not exist in the form of beads, it folds into a specific shape, depending on the amino acid sequence and the way it interacts, which affects the role of the protein in the body.
amino acids come from? The amino acids in the body come from the foods we eat, and of course we also make amino acids in the body, for example, other animals make proteins, and we get proteins by eating meat from these animals; The system breaks down into amino acids, which are taken into cells and floated in cells, like the little beads we like, and then in cells, the machine connects them together to make the proteins needed; we can make about half of the amino acids the body needs, and the rest can be obtained from food.
proteins play a role in the body? Scientists aren't sure, and most people agree that there are about 20,000 different proteins in the body, and studies have shown that even more proteins perform many different functions to convert the body's metabolism and promote cells to stay together. These functions of
proteins can be divided into several categories, first of all structural, our body is composed of many different structures, imagine the line structure, spherical structure, etc. ; Another important role played by
proteins is that they perform special bio-chemical reactions in the body's cells, such as breaking down fats or amino acids;
proteins process signals and information, such as circadian rhythm proteins that hold time in cells.
protein is often closely related to muscle and meat? Different types of food contain many different protein content, such as wheat and rice plants have a lot of carbohydrates, its protein content is not rich, but the general meat is more protein content, the body's muscles also need a lot of protein to make, so that is why protein is often closely linked to eating meat and building muscle, but the role of protein in the body may be far less.
