Document Summary
Contain carbon, hydrogen, and oxygen like lipids and carbs. Amino acids-nitrogen containing chemical units that make up proteins. Organic nutrients that are similar to lipids and carbohydrates. Fibrin-tough protein that forms when blood clot needs to stop bleeding. Hemoglobin- transports oxygen and carbon dioxide in red blood cells. Retinol binding protein- carries vitamin a in the bloodstream. Proteins in cell membrane control movement of stuff in and out of cell. In blood that help prevent and combat infections. Protein in blood helps maintain distribution of fluids (albumin) When body has inadequate amounts of protein the level of protein in blood decreases then water leaks out of blood and goes between cells. Acid based balance- correct concentration of hydrogen ion (h+) in body fluids. If h+ increases too much it"s too acidic, if decreases too much tissues become too basic (alkaline) Proteins are a buffer that helps prevent this. Cells metabolize a small amount of protein for energy.
