Distinct biochemical pathways for nitrogen in living organisms can be detected by stable isotope tracers and may be useful in the interpretation of kerogen from ancient, sedimentary rocks. The organic matter in stromatolite growths of thermal springs

Both natural populations and laboratory cultures of the marine amphipods, Parhyale hawaiensis (Dana) and Amphithoe valida Smith, have similar isotopic relationships to their food sources. Amphipods, which ate the red alga Gelidium , had an isotopic c

Stromatolites forming today on a small scale in hydrothermal environments are chemical and biological analogues of much larger Precambrian formations. Carbon isotopic composition varied as a function of CO 2 concentration, pH, and species composition

This study evaluates a kinetic isotope effect involving 15N, during the transamination reactions catalyzed by glutamic oxalacetic transaminase. During the transfer of amino nitrogen from glutamic acid to oxaloacetate to form aspartic acid, 14NH2 reac

The hydrogen isotopic content of an animal's food, not water, determines that animal's hydrogen isotopic content. Liver and muscle tissue from mice reared on a diet such that the ratio of deuterium to hydrogen (DIH) of their food and water was kept c
