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.
1 Sickle/beta-thalassemia. 2  In this condition, the patient has inherited a gene for hemoglobin S from one parent and a gene for beta-thalassemia from the other. 3  The severity of the condition is determined to a large extent by the quantity of normal hemoglobin produced by the beta-thalassemia gene. Hemoglobin C. Hemoglobin C results from a mutation in the beta globin gene and is the predominant hemoglobin found in people with hemoglobin C disease (a 2 b 2). 2  Hemoglobin C disease is relatively benign, producing a mild hemolytic anemia and splenomegaly.
