SYNTHESIS AND DETERMINATION OF THE LIPOTROPIC ACTIVITY OF THE BETAINE HYDROCHLORIDES OF dl-SERINE, GTHREONINE, AND dl-ALLOTHREONINE*
This paper reports the synthesis of the betaine hydrochlorides of serine, threonine, and allothreonine and a study of the action of these substances on the lipid content of the livers of rats fed a high fat, low protein diet. This work was undertaken for two purposes. Best and Huntsman (1) found that choline prevented the development of fatty livers in rats fed a high fat diet and that betaine ...

متن کاملThe formation of glycine and serine; the influence of the administration of glycine, DL-serine and other compounds on levels of tissue glycine and serine.
The rates of conversion of glycine into serine and serine into glycine have been determined by administration of isotopically labelled glycine and serine (Arnstein & Neuberger, 1953; Elwyn & Sprinson, 1954; Arnstein & Keglevi6, 1956; Arnstein & Stankovid, 1956). The present investigation, which is concerned with the net synthesis of glycine from serine, and of serine from glycine, was carried o...
متن کاملLow-temperature infrared spectra and hydrogen bonding in polycrystalline DL-serine and deuterated derivatives
The FT-IR spectra of polycrystalline DL-serine [a-amino-b-hydroxypropionic acid; HO–CH2–CH(NH3) –COO ] and isotopically substituted [ND/ODAlcohol (<10% and >90% D); CD2 (>98% D)] DL-serine were recorded in the range 4000–500 cm 1 in the temperature range 300–10 K, and fully assigned. The isotopic-doping/low-temperature methodology, which allows for decoupling of individual proton vibrational mo...
متن کاملAHIM ACIDS; 13'. INVESTIGATIONS ON THE SYNTHESIS OF DL-SERINE FRUH a-HALDACRYLIC ACID DERIVATIVES FRANZ EFFENBERGER* and CERHARD ZOLLER'
The alkoxide-catalyzed addition of alcohols 2 to a-chloroacrylonitrile (1) at -35°C gives rise to 3-alkoxy-2-chloropropancnitriles 3; at D-5°C with excess _2 alkyl 3-alkoxy-2-chloropropanicidates 3 are obtained. The yields of 3 or 4 decrease with increasing pK, values of the alcohols 2. In the basecatalyzed addition of phenols 5 to 1, a temperature-dependent addition equilibrium is set up in wh...
