glutamine

 [gloo´tah-min]
an amide of glutamic acid, one of the nonessential amino acids; it is an important carrier of urinary ammonia and is broken down in the kidney by the enzyme glutaminase.

glu·ta·mine (Gln, Q),

(glū'tă-mēn, -tă-min, glū-tam'in),
The δ-amide of glutamic acid, derived by oxidation from proline in the liver or by the combination of glutamic acid with ammonia; the l-isomer is present in proteins, blood, and other tissues, and is an important source of urinary ammonia, being broken down in the kidney by the action of the enzyme glutaminase; nonenzymatically, it is converted to 5-oxoproline.

glutamine

(glo͞o′tə-mēn′)
n.

glu·ta·mine

(Gln) (glū'tă-mēn)
