Finally, dietary deprivation of the methyl donors methionine and choline had been shown to induce liver carcinomas in rats (Copeland and Salmon, 1946). Although these findings were accepted for a period of nearly 10 years, the subsequent demonstration

It involves N-methylation of lysine, arginine, histidine, alanine, proline, and glutamine, O-methylation of glutamic and aspartic acid, and S-methylation of methionine and cysteine (Paik & Kim, 1985). As shown in Table I, methylated amino acids occur in high
