  • Note:—Glc indicates glucose; Lac, lactate; Lip, lipids; Val, valine; Leu, leucine; Ile, isoleucine; and Ala, alanine.

  • * Peak resonances of Glc, Lac, and Lip detected and arbitrarily assigned to 1 of 3 grades, low (+), medium (++), or high (+++) on the basis of the ratio of the integral of the metabolite peak to the integral of unsuppressed water peak. For Val, Leu, Ile, and Ala, only their presence is indicated.
