** see formulas ** a) conversion of D-aspartic or L-aspartic acid (1) into D-aspartic acid or substituted N-Y-aspartic acid (2); b) conversion of the substituted N-Y D-aspartic acid or L-aspartic acid (2) into the respective anhydride (3); c) reduction of the anhydride (3) ...
Administration of 2.0 mol/g D-Asp in frogs during both periods induces the release of secretory granules in the hg. This effect is more evident in July, when the amino acid accumulates at the apex of the cells beneath the plasma membrane. Such evidence suggests a role of D-Asp in the ...
