Ethanolamine and phosphonic acid complexes in heat-treated Tetrahymena cells☆
Review articleOpen access

Abstract1.1. Three acid soluble phosphorus-containing compounds (referred to as Nos. 17, 18, 19) were isolated from Tetrahymena cultures incubated at supra-optimum temperature for 3 hr.2.2. Compound No. 17 appears to be identical to compound No. 19 in respect to glycerol, “sugar” and a “sugar”-phosphate moiety. In addition, compound No. 17 contains ethanolamine, while compound No. 19 is ninhydrin negative. The “sugar” phosphates of both compounds can be hydrolyzed by acid phosphatase.3.3. One “sugar” moiety in compound No. 18 is the same as in compounds Nos. 17 and 19. The positive ninhydrin reaction in compound No. 18 is due to the presence of 2-aminoethylphosphonic acid and possibly another phosphonic acid.4.4. All three compounds are found in the water phase of a centrifuged homogenate of heat-treated cells, but only compounds Nos. 17 and 19 are present in the pellet.
