Why are alanine and glutamine the most abundant amino acids in blood?
Glutamine and glutamate work together to move nitrogen from the mitochondria
to the cytoplasm, and in the process, export alanine.
Glutamine is required for the urea cycle and alanine is the precursor for
pyruvate, which is needed for gluconeogenesis.
Glutamine is an important neurotransmitter and also responsible for unami
flavoring (monosodium glutamine; MSG); alanine is a small amino acid.
Glutamine carries nitrogen from most tissues to the liver and alanine carries
nitrogen to the liver from muscle cells.
