l-Threonine ethanolamine phosphate: a compound newly isolated from fish

Abstract

Isolation of L-threonine ethanolamine phosphate from trout. Liver, intestinal tract, kidneys, spleen and gonads were removed immediately after death and frozen. The pooled material (1050 g.) was extracted in a large-capacity Waring Blendor with 2-0 1. of 15N-perchloric acid. After

Influence of Phosphoserine on the Performance of Rats on the Rotarod

“…Many researchers over the course of the last 10 years have led their studies to the identification (Rosemberg et al, 1972;Porcellati, 1963;Bridgers, 1967) and distribution (Porcellati, 1964;Ansel and Chojnacki, 1966;Forsberg et al, 1969;Rask et aL, 1970;Hubscher, 1962;Knox et al, 1969) of several amino compounds including ¿-serine and its phosphoester in the tissues of a variety of animals. Recently, it was pointed out that phosphoserine may play an important role in the phospholipid synthesis in the microsomes of the central nervous system cells (Pirotta and Guazzoni, 1971;Porcellati et al, 1970;Arienti et al, 1970).…”

The Isolation and Identification of L-Lanthionine and L-Cystathionine from Insect Haemolymph*

“…The effluent was collected in 45-ml fractions at a flow rate of 11 ml/min. Ninhydrin-reacting material contained in each fraction was detected as described by Rosenberg et al (1962). The amino acids in each fraction were subsequently identified by paper chromatography and by a Beckman automatic amino acid analyzer (Model 120B) using a 50-cm column on the accelerated system; a 30-50°schedule was followed with the temperature change at 2.5 hr and the buffer change at 2 hr and 40 min.…”
