It is identical' with the hydrotropilidine, which results by the destructive methylation of tropane.
By the electrolytic reduction of pseudopelletierine, N-methyl granatanine is obtained, and this by exhaustive methylation is converted into A O des-dimethyl granatanine.
Early in development of the fetal germ cells in both sexes, the germ-cell genomes are erased of methylation marks on the imprinted genes.
To this end, the polysaccharide preparations have been subjected to enzymic hydrolysis and methylation analysis.
Differential methylation of DNA sequences associated with imprinted genes is thought to control genomic imprinting, which occurs soon after fertilization.
