Change the direction of your ABS piping with these elbows. The 45Â° bend helps you change direction gradually to reduce the chance of clogging. Drain, waste, and vent pipe and fittings are recommended for indoor use in residential and light commercial buildings. Not recommended for pressure.
This mutation in the beta-hemoglobin gene results in the change of just a single amino acid within the polypeptide encoded by that gene. The sixth amino acid in beta-hemoglobin is normally glutamate, which has an acidic, very polar, âhydrophilicâ (water-attracting) side chain.ach red blood cell contains millions of molecules of hemoglobin, the protein that does the work of oxygen transport. The hemoglobin molecule is composed of four polypeptides (chains of amino acids): two alpha (Î±) chains, each with 141 amino acids, and two beta (Î²) chains, each with 146 amino acids.
sickle cell anemia a common form of sickle cell disease is caused by a particular mutation in the hbb gene this mutation results in the production of an abnormal version of beta globin called hemoglobin s or hbsin this condition hemoglobin s replaces both beta globin subunits in hemoglobineta globin is a component subunit of a larger protein called hemoglobin which is located inside red blood cells in adults hemoglobin normally consists of four protein subunits two subunits of beta globin and two subunits of another protein called alpha globin which is produced from another gene called hba
