What is the nitrogenous compound that is the waste product of amino acids?
Amino Acids, the monomers within Protiens, are the majog
nirtogen containing chemicals in the body. Alph-Keto-Gluterate is a
very special compound in the body that can freely accept a Ammonia
group (aminno group). With this group addes it is called Glutamate,
one of the 20 coded amino acids. This amino acid is also very
special as it has the ability to pass the nitrogen on to other
amino acids, take them away from other amino acids or, by combining
the two, pass them between two amino acids. Nitrogen from most body
tissue protein (not skeletal muscle but that a different story
entirely) passes from the amino acids onto the glutamate which then
takes up another ammonia group from the blood to form glutamine.
The glutamine the travels round the blood until it gets to the
liver where it is split into glutamate and ammonia again. The
glutamate then drops it own ammonia group, becoming
alpha-keto-gluterate again. These two ammonia compounds are turned
into the nitrogen containing waste substance Urea. Urea is then
exreted from the body through the kidneys. So sum up my rather
longwinded answer, more inormation is better than not enough, The
Nitrogen containing waste product of amino acids is Urea.
