Nitrogen Flashcards
What is the main source of nitrogen in the body?
Glutamine
What nitrogen containing amino acids are used to make delta-ALA?
Glycine
Glutamate
What is delta-ALA required for?
The synthesis of heme
What genetic disorder is associated with the use of delta-ALA for the synthesis of heme?
Porphyrias
What nitrogen containing amino acids are used to make creatine and phosphocreatine?
Glycine
Arginine
What is phosphocreatine used for?
To replenish ATP levels
What amino acids are used in the synthesis of glutathione?
Glutamate
Glycine
Cystine (two cysteines joined by a disulphide bond)
What two forms is glutathione found in?
GSH = reduced GSSG = oxidised
What does the ratio if GSSG to GSH tell us about the body?
The higher the levels of GSSG the greater oxidative stress the body is in
What aromatic amino acid products are found in plants?
Lignin
Auxin
