alanine /al·a·nine/ (Ala) (A) (al´ah-nēn) a nonessential amino acid occurring in proteins and also free in plasma.
alanine (Ala) 
alanine (al´
nēn),
β-alanine an amino acid not found in proteins but occurring free and in some peptides; it is a precursor of acetyl CoA and an intermediate in uracil and cytosine catabolism.
al·a·nine ( l  -n n )n. Abbr. Ala A crystalline amino acid that is a constituent of many proteins. |
alanine (Ala)
[al′ənin]
a nonessential amino acid found in many food protein sources as well as in the body. It is degraded in the liver to produce important biomolecules such as pyruvate and glutamate. Its carbon skeleton also can be used as an energy source.

Chemical structure of alanine
alanine (al´
nēn),n a nonessential amino acid found in many proteins in the body. It is metabolized in the liver to produce pyruvate and glutamate.
alanine
a naturally occurring, nonessential amino acid.
alanine cycle
cycle of alanine produced in muscle from transamination of pyruvate produced from glycolysis of glucose during exercise, transported in the plasma to the liver where the alanine amino-nitrogen is converted to urea for excretion and the carbon from the keto-acid of alanine, pyruvate, is recycled via gluconeogenesis to glucose, which is finally transported back to the muscle.
