iron absorption - -ferric iron is taken in from diet -ferric iron is reduced by duodenal cytochrome B to become ferrous iron -ferrous iron is absorbed into enterocytes by DMT 1 -absorbed iron is stored as ferritin, or sent into portal hepatic circulation and carried by transferrin to developing RBCs transferrin - plasma carrier protein for ferrous iron high iron level regulation - -hepcidin is released from hepatocytes -ferroportin is inactivated, leading to decreased iron being transp...

ACS BIOCHEMISTRY EXAM 2023 Q&A With complete solution Henderson-Hasselbach Equation - ANSWER pH = pKa + log ([A-] / [HA]) FMOC Chemical Synthesis - ANSWER Used in synthesis of a growing amino acid chain to a polystyrene bead. FMOC is used as a protecting group on the N-terminus. Salting Out (Purification) - ANSWER Changes soluble protein to solid precipitate. Protein precipitates when the charges on the protein match the charges in the solution. Size-Exclusion Chromatography - ANSWER Se...
