Carbohydrates Flashcards
Enzyme defect in glycolysis that causes
CHRONIC HEMOLYTIC ANEMIA
Pyruvate Kinase Deficiency
Inhibits pyruvate dehydrogenase and binds to lipoic acid
competes with inorganic phosphate as substrate for glyceraldehyde 3-p- dehydrogenase
Arsenic Poisoning (Pentavalent)
Low exercise capacity, particularly on high carbohydrate diet
Muscle Phosphofructokinase Deficiency
X linked dominant
Congenital lactic acidosis
Increase lactate
Decease acetyl CoA
Pyruvate Dehydrogenase Deficiency
Acquired PYRUVATE DEHYDROGENASE deficiency that leads to fatal pyruvic and lactic acidosis
Chronic alcoholism
High amount of NADH is formed by what (2) enzymes
Alcohol dehydrogenase
Acetaldehyde dehydrogenase
High amounts of NADH favor what (3) reactions
pyruvate to lactate
oaa to malate
DHAP to glycerol-3-p
Glucose 6 phosphatase deficiency
Von gierke
Acid maltase deficiency
Pompe
Debranching enzyme defiency
Cori’s
Skeletal muscle glycogen phosphorylase defiency
Mc Ardles
Branching enzyme deficiency
Andersen’s
Disease Findings:
Glycogen: liver and renal cell
Hypoglycemia, hepatomegaly, lactic acidosis
VON GIERKE
Disease Findings:
Glycogen: lysosomes
Cardiomegaly and heart failure
Pompe
Disease Findings:
Glycogen: muscle
Myoglobinuria but no lactic acidosis
