![]() ![]() Proteins can supply your body with energy. Proteins act as a buffer system, helping your body maintain proper pH values of the blood and other bodily fluids. The other buffer systems in your body include phosphate and bicarbonate ( 16). Hemoglobin binds small amounts of acid, helping to maintain the normal pH value of your blood. An example is hemoglobin, a protein that makes up red blood cells. One way your body regulates pH is with proteins. It ranges from 0 to 14, with 0 being the most acidic, 7 neutral and 14 the most alkaline.Įxamples of the pH value of common substances include ( 18):Ī variety of buffering systems allows your bodily fluids to maintain normal pH ranges.Ī constant pH is necessary, as even a slight change in pH can be harmful or potentially deadly ( 19, 20). The balance between acids and bases is measured using the pH scale. Protein plays a vital role in regulating the concentrations of acids and bases in your blood and other bodily fluids ( 16, 17). ACTH (adrenocorticotropic hormone): Stimulates the release of cortisol, a key factor in metabolism.Īmino acid chains of various lengths form protein and peptides, which make up several of your body’s hormones and transmit information between your cells, tissues and organs.ADH (antidiuretic hormone): Signals the kidneys to reabsorb water.hGH (human growth hormone): Stimulates the growth of various tissues, including bone.Glucagon: Signals the breakdown of stored glucose in the liver. ![]() Insulin: Signals the uptake of glucose or sugar into the cell.Protein and polypeptides make up most of your body’s hormones. Amines: These are made from the individual amino acids tryptophan or tyrosine, which help make hormones related to sleep and metabolism. ![]() The sex hormones, testosterone and estrogen, are steroid-based.
