Term
prophyrin 9
Definition
what is the most common metalloporphyrin and is found in humans?
Term
3
Definition
what is the only poryphin that is physiologically important in humans?
Term
pyridoxal phosphate; Hemin
Definition
The synthesis of ALA catalayzed by ALA synthase requires what enzyme? what is the inhibitor?
Term
glycine and succinyl CoA
Definition
in the reaction where ala is catalayzed by ala synthase what are the substrates?
Term
uroporphyrinogen III
Definition
If you have a defiency and you do not form coproporphyrinogen III what will be present in the urine?
Term
prophorinogen
Definition
Lead poisoining is due to an incerease in ALA because of an absence of ?
Term
AD
Definition
Porphyrias, which are inherited disorders of HEME synthesis are inherited usually by what mode?
Term
sigma-aminolevulinate
Definition
if this is inhibited you will have red wine or colored urine, red flourescent teeth
Term
prophobilinogen and ALA
Definition
If you have hydroxymethylbilane synthase deficiency what will accumulate in the urine?
Term
corporphyrinogen III, and the intermediates
Definition
if you have a copropophyrinogen oxidase deficiency what will accumulate in the urine
Term
protoporphyrinogen IX and other intermediates
Definition
If you have a deficiency in protoporphyrinogen oxidase what will accmulate in the urine?
Term
Uroporphyrin
Definition
If you have a deficiency in uroporphyrinogen decarboxylase what will accumulate in the urine?
Term
Gunther's
Definition
if you have a deficiency with uroporphyrinogen III synthase
Term
HEME oxygenase
Definition
The Heme ring is opened up in the ER by?
Term
phenobarbitol
Definition
what induces the synthesis of UDP-Glucuronyl Transferase?
Term
prehepatic
Definition
in this type of jaundice you are making too much bilirubin because of hemolysis (sickle cell disease)
Term
Intrahepatic
Definition
in this type of jaundice you would have a problem in the liver, genetic errors, and conjugating enzymes in liver are not mature. There is a problem with the hepatocytes and AST and ALT are increased
Term
post-hepatic
Definition
in this type of jaundice there is a blockage of the bile duct, bile acids accumulate in the plasma and you will have pale color stools and dark urine. Complete obstruction or urobilin is absent (unconjugated bilirubin) an increase in alkaline phosphotase will be seen as well
Term
Tyrosine Hydroxylase; TBH
Definition
what is the rate limiting enzyme that converts tyrosine to DOPA and what is the cofactor that it requires?
Term
PNMT
Definition
what is enzyme that allows norepinephrine to be converted to epinephrine
Term
COMT and MAO
Definition
Dopamine, norepinephrine, and epinephrine are removed by ?
Term
Homovanilic Acid
Definition
Dopamine is finally converted to?
Term
Vanillylmandelic Acid
Definition
Norepinephrine and epinephrine are finally converted to?
Term
Tryptophan Hydrolase; THB
Definition
Tryptophan is converted to serotonin by what enzyme and what is the cofactor?
Term
creatine
Definition
made from arginine, glycine, and methionine
Term
protein kinase
Definition
if this is present in the plasma it indicates tissue damage and is used in diagnosing MI
Term
Diazo Reaction and Diazotized sulfanic acid+Biliruin
Definition
what are the methods for producing bilirubin (2)?
