  • Title: Two-dimensional proton magnetic resonance of human muscle extracts.
    Author: Venkatasubramanian PN, Arús C, Bárány M.
    Journal: Clin Physiol Biochem; 1986; 4(5):285-92. PubMed ID: 3022979.
    Abstract:
    In continuation of our previous work on one-dimensional (1D) proton nuclear magnetic resonance (1H-NMR) of normal and diseased human muscle extracts we recorded the two-dimensional (2D) J-correlated proton magnetic resonance spectra of these extracts. Significant differences between normal and diseased muscle extracts, not observed in the 1D 1H-NMR spectra, were seen from their 2D connectivity contour patterns. Taurine was not present in cerebral palsy muscle extract while both normal and scoliosis muscles contained this metabolite. Only the normal muscle had carnitine. Carnosine was present in all muscles. alpha-Ketoglutarate was found only in the diseased muscle extracts. While the amino acids lysine, cysteine and glutamine were common to normal and diseased muscles, threonine was seen only in the diseased muscles. Additional small differences were detected in the 2D patterns of human muscle extracts.
