what is the function of protein in metabolism?

Answer 1

Complex proteins are absorbed from the digestive tract and are broken down into about 20 amino acids needed for cellular anabolism. Amino acids may undergo further chemical change to form such internal secretions as hormones and digestive enzymes. Amino acids in excess of those required to replenish body cells and fluids are catabolized in two steps. The first is deamination, in which the nitrogen-containing part of the molecule is removed and united with carbon and oxygen to form urea, ammonia, and uric acid—the nitrogenous products of protein metabolism. Following deamination, each of the remaining amino acids undergoes further chemical breakdown to form other compounds, which are then still further catabolized, often by pathways common to those of similar products from the catabolism of carbohydrates and fat. The end products of these protein portions are carbon dioxide and water.

Answer 2

Proteins are made of strings of amino acids that form chains known as peptides. Our bodies need dietary protein to accomplish many basic functions, such as building bones, moving muscles, and repairing tissue. Dietary protein, an essential nutrient, comes from meat, dairy, and certain grains and beans.

As building blocks for our tissue and a catalyst in metabolism, dietary protein's jobs are almost too many to enumerate. Our digestive system breaks down protein to its amino acid constituents. They're involved in the nervous system, repairing and maintaining tissue such as bones and skin, and bringing energy to cells. Dietary requirements vary from 1.4-2.5 oz (40-70 g) of protein per day. Too much protein might deplete calcium, while too little causes a form of malnutrition called kwashiorkor. Insufficient protein weakens the heart and other muscles, eventually leading to death. Incidentally, proteins are responsible for most food allergies.

Answer 3

proteins are made of peptides which are made of amino acids. these are the basic fuels to keep you alive and thinking.

in short protein gives you energy and keeps your brain working.
