ACS BIOCHEMISTRY EXAM QUESTIONS AND ANSWERS Henderson-Hasselbach Equation - answerpH = pKa + log ([A-] / [HA]) FMOC Chemical Synthesis - answerUsed 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) - answerChanges soluble protein to solid precipitate. Protein precipitates when the charges on the protein match the charges in the solution. Size-Exclusion Chromatography - answerSeparates sample b...

organic chemical -:- also referred to as an organic compound, is defined as being constructed of molecules that possess carbon-based atoms. Specifically, it is composed of carbon atoms attached to hydrogen atoms, together with a variety of other elements from functional groups, such as oxygen, nitrogen, sulfur, etc. Usually, an organic chemical is covalently bonded, meaning that electrons are shared between atoms. This characteristic is why organic chemicals can be structured in a va...

What is hemoglobin composed of? - Answer-4 heme, 4 iron, 4 globins What disorder does a defect in heme synthesis lead to? - Answer-Porphyria Porphyria - Answer-Deficiency in the enzymes of the porphyrin pathway leads to insufficient production of heme. The principal problem in these deficiencies is the accumulation of porphyrins, the heme precursors, which are toxic to tissue in high concentrations. What is methemoglobin? - Answer-Methemoglobin is a form of hemoglobin that contains ferric [...

____________ and ____________ are required for heme synthesis - Answer- iron and protoporphyrin Fe Transport protein - Answer- Transferrin Major Fe storage form - Answer- Ferritin H2O insoluble Fe storage form (long-term) - Answer- Hemosiderin Excess iron that is stored in tissues and body organs can lead to ____________ and ____________ - Answer- hemosiderosis and hemochromatosis (organ damage) What are the heme precursors (in order) - Answer- Delta, Porphobilinogen, UR, COP, P...

MULTIPLE CHOICE.

A client with diagnosed iron deficiency anemia comes to you because he eats meat based protein and green leafy vegetables but his iron levels have not increased. What other nutrient is needed to properly absorb iron? 1.) Vitamin B12 2.) Folic Acid 3.) Intrinsic factor 4.) Vitamin C  4.) Vitamin C Antacids can reduce the absorption of iron and copper, leading to iron deficiency anemia because: 1.) Because the antacids bind the metals 2.) Acidic pH increases Fe3+ 3.) DMT1 require...

Ligand correct answers A molecule which is reversibly bound by a protein; A small molecule that binds specifically to a larger one; for example, a hormone is the ligand for its specific protein ligand. Induced Fit correct answers Proteins or enzymes may undergo conformational changes when a lignand binds which alters the function of the protein; What do Myoglobin and haemoglobin contain? correct answers They contain a hem prosthetic group which binds oxygen. What does Heme consist of? c...
