alanine

 [al´ah-nēn, al´ah-nin]
a nonessential amino acid, also found at high levels in plasma.

al·a·nine (A, Ala),

(al'ă-nēn),
2-Aminopropionic acid; α-aminopropionic acid; the l-stereoisomer is one of the amino acids widely occurring in proteins.

alanine

/al·a·nine/ (Ala) (A) (al´ah-nēn) a nonessential amino acid occurring in proteins and also free in plasma.
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.

alanine

(ăl′ə-nēn′)
n.
A nonessential amino acid, C3H7NO2, that is a constituent of many proteins.

alanine (Ala or A)

[al′ənin]
a nonessential, nonpolar (neutral) 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

A simple, nonessential amino acid—CH3CH(NH2)COOH—found in most proteins, which is involved in glucose catabolism, especially in anaerobic conditions.

al·a·nine

(A, Ala) (al'ă-nēn)
2-Aminopropionic acid; α-aminopropionic acid; one of the amino acids widely occurring in proteins.

alanine (A, Ala)

one of 20 AMINO ACIDS common in proteins. It has a NON-POLAR structure and is relatively insoluble in water. The ISOELECTRIC POINT of alanine is 6.0. See Fig. 19 .

al·a·nine

(A, Ala) (al'ă-nēn)
2-Aminopropionic acid; α-aminopropionic acid; one of the amino acids widely occurring in proteins.

alanine (al´ənēn),

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.
