- Glucose-6-phosphatase deficiency (G6PD), also known as von Gierke disease, is glycogen storage disease. It is an autosomal recessive disease occurring most frequently in males of African or Middle Eastern descent. G6PD is involved in many reactions, but we will focus on the following simplified pathway: The conversion of glycogen to glucose is called:arrow_forwardChoose the CORRECT sequence of glycine formation. transamination of 3-phosphoglycerate → hydrolysis of 3-phosphohydroxypyruvate → hydrolysis of 3-phosphoserine → transfer of the side-chain methylene group of cysteine to tetrahydrofolate → glycine transamination of 3-phosphohydroxypyruvate → oxidation of 3-phosphoglycerate → transfer of the side-chain amino group of serine to tetrahydrofolate → glycine oxidation of 3-phosphoglycerate → oxidation of 3-phosphohydroxypyruvate → hydrolysis of 3-phosphoserine → glycine transamination of 3-phosphohydroxypyruvate → hydrolysis of 3-phosphoserine → oxidation of 3-phosphoglycerate →transfer of the side-chain methylene group of serine to tetrahydrofolate → glycine oxidation of 3-phosphoglycerate → transamination of 3-phosphohydroxypyruvate → hydrolysis of 3-phosphoserine → transfer of the side-chain methylene group of serine to tetrahydrofolate → glycinearrow_forwardWhen transaminated, the three branched-chain amino acids (valine, leucine, and isoleucine) form compounds that have the characteristic odor of maple syrup. An enzyme known as branched-chain a-keto acid dehydrogenase converts these compounds into CoA esters. People who do not have this enzyme have the genetic disease known as maple syrup urine disease, so called because their urine smells like maple syrup. a. Draw the compounds that smell like maple syrup.b. Draw the CoA esters.c. Branched-chain a-keto acid dehydrogenase has five coenzymes. Identify them.d.
