S-adenosylmethionine (SAM) has antidepressant properties. The commonest neuropsychiatric complication of severe folate deficiency is depression. These independent observations suggest that methylation in the nervous system may underlie the expression of mood and related processes and may be implicated in some affective disorders; suggest new biological

Archives of General Psychiatry, 1979
L-Methionine had no behavioral effects in normal humans and failed to increase concentrations of S-adenosylmethionine (methyl donor) in human or rat blood, while increasing rat liver levels more than fivefold. Methionine or S-adenosylmethionine in very high doses had almost no effect on methylation of tritiated levodopa in rodent tissues; various ...

Partial methylation of methyl glycosides
Chemistry of Natural Compounds, 1975The partial methylation of methyl xylo-, arabino-, lyxo- and rhamnopyranosides by Purdie's method has been studied; it is possible to use the results obtained for the isolation of individual methyl ethers by micro-preparative GLC.
