What does protein do in the human body

Protein: function in the body

Structural proteinsGive different proteins Cells their shape and Weave their strength. Typical structural proteins are collagen (hair and nails), keratin (connective tissue and cartilage) and elastin (gives blood vessels their elasticity).Contractile ProteinsThe most important contractile proteins include actin and myosin. They make a Contract muscle can. Without these proteins you could be yourself dont move.Storage proteinsThe human organism needs protein in order to to store certain substances. For example, humans would not be able to store iron without the protein ferritin.
In extreme hunger situations, the human organism can even use these proteins as a Energy source use.Transport proteinsAn important function of certain proteins is to make various substances like in the body Transporting oxygen or fat - they are therefore also called transport proteins. These include, for example, the proteins albumin, hemoglobin and myoglobin.Protective proteinsWhen pathogens get into the body, it defends itself by, among other things, so-called antibody forms. Antibodies are proteins that fight the pathogen and the body protect against disease.
In addition, the human organism needs the protein fibrinogen for Blood clotting. When you injure yourself, your body converts fibrinogen into fibrin, which is like a grid over the wound.HormonesMany hormones are proteins that are important in the body Taxes. These are mostly very short proteins with fewer than 100 amino acids - they are therefore also known as Peptide hormones or proteohormones.
The best-known peptide hormones include insulin and erythropoietin (EPO).EnzymesFrom a chemical point of view, almost all enzymes are proteins. Enzymes are for that metabolism, but also of central importance for many other bodily functions. More precisely, the function of the enzymes is to chemical reactions in the body to accelerate or to let it run at all.
