title: Proteinoid microspheres more stable in hot than in cold water.
abstract: The occurrence of organisms of primitive appearance near submarine hydrothermal vents has indicated sea-floor conditions that are like those under which proteinoid microspheres are produced in the laboratory. Experimental examination of the question of whether some proteinoid microspheres might be stable in hot water has revealed proteinoids that are soluble in cold water but precipitate on heating. Unanswered questions are discussed.
