Pernicious anemia is a disease in which the intestine is unable to absorb vitamin B12, frequently due to the loss of the generically named "intrinsic factor" produced by the parietal cells of the stomach lining. Intrinsic factor is a glycoprotein that binds to vitamin B₁2 and is required for its uptake in the ilium. Vitamin B12 is synthesized only by microbes, and we get it either from digesting animal protein or from our commensal microbiome. Vitamin B₁ is unique among metabolic cofactors in that it contains the trace element cobalt, coordinated in a corrin ring structure that is similar to the porphyrin ring system in heme. Loss of intrinsic factor, often through autoimmunity, results in the inability to absorb B12 and ultimately a loss of red blood cells that results in anemia and can be deadly ("pernicious"). ILEUM NUMBNESS (a) In pernicious anemia, N 5-methyltetrahydrofolate accumulates, and cells run out of…

Explain what it means for an active site to have electronic and shape complementary. Give hypothetical examples of each. A researcher is studying three different synthetic collagens. Collagen A is made of (Pro-Gly- Hyp)10, Collagen B is made of (Pro-Gly-Flp)10, and Collagen C is made of (Pro-Gly-Thr)io. Based on the collagen studies we did in class, which one (A, B, or C) B a) b) ( is the most like normal collagen - would be the most stable and why - because it contain fluorine which is very electronegative would be the least stable and why- c is the least stable
