AND EXCRETION Bilirubin‚ the principal pigment in bile‚ is derived from the breakdown of hemoglobin when aged red blood cells are phagocytized by the reticuloendothelial system‚ primarily in the spleen‚ liver and bone marrow. About 80% of bilirubin formed daily comes from the degradation of hemoglobin. The remainder comes from destruction of heme-containing proteins and catabolism of heme. When hemoglobin is destroyed‚ the protein portion‚ globin is reused in the body. The porphyrin is broken down

had shown about 1912 that plants contain two chlorophylls: chlorophyll a and chlorophyll b. From chlorophyll he obtained three different porphyrins‚ and from these etioporphyrin‚ which he considered identical with the etioporphyrin obtained from hemoglobin. Fischer started his researches here‚ and from the three porphyrins he obtained two distinct etioporphyrins. He synthesized very many isomers‚ and he converted pyroporphyrin into his mesoporphyrin IX. He then worked on the substance phylloerythrin

transfusion. In a situation where a person has lost lot’s of their blood because of an accident‚ has really low hemoglobin. This person would not be in a good situation because hemoglobin is the structure in the blood which carries oxygen in the arteries which will eventually go to your organs. With a blood transfusion‚ the person will receive red blood cells which would increase the hemoglobin level and allow for more oxygen to provide strength to every organ of the human body. When blood is lost‚ the

Sickle cell anemia is a blood disorder that affects the 11th chromosome which is a hemoglobin gene. Hemoglobin is a protein located in red blood cells (RBCs) that carries oxygen through the body. This disorder is inherited from two parents with abnormal genes that are heterozygous (Rr). This means that both parents who have the trait may pass on the disorder to their offspring. The phenotype makeup is recessive. Those who inherit a normal copy of the chromosome 11 and a mutated chromosome will carry

1) A peptide‚ KKDSRHSTTR is tightly bound to a negatively charged ion exchange column. The column is washed with a pH 7.2 HEPES buffer (50 mM) and the peptide does not elute. Suggest two ways that you can change the buffer that will make the peptide elute from the column. 2) What amino acid(s) is/are involved in crosslinking polypeptide chains. How can these crosslinks be cleaved and prevented from reforming? 3) A polypeptide is subjected to the following degradative techniques results

Hematocrit/Hemoglobin: Anytime a child has an abnormal Hematocrit/Hemoglobin result‚ (Hematocrit-less than 34% or 45% or more and Hemoglobin-less than 11 gms or 15.5 gms or more). Hematocrits/Hemoglobins are obtained following the EPSDT periodicity schedule‚ which require a screening at 9 months of age and then again between 10 years and 20 years of age.

discussed‚ along with the signs‚ symptoms and treatment for Sickle Cell Anemia. Sickle Cell Anemia is a genetic disorder dealing with the red blood cells within the body. The abnormality deals with the formation of hemoglobin within the blood cells. The hemoglobin abnormality is called hemoglobin S. The Sickle Cell gene need to be inhered from both of the parents‚ otherwise the individual will only carry the Sickle Cell trait. If the sickle cell trait is carried by an individual they can be asymptomatic

A mutation can simply be put as abrupt change in the genotype of an organism that is not the result of recombination. A gene mutation is a permanent change in the DNA sequence that makes up a gene. Mutations range in size from a single DNA building block (DNA base) to a large segment of a chromosome. Gene mutations occur in two ways: they can be inherited from a parent or acquired during a person’s lifetime. Mutations that are passed from parent to child are called hereditary mutations or germ
