Organic oxygen and hydrogen isotopes in a porcine controlled dietary study.
Controlled feeding studies have been useful in assessing the relationship between isotope values from dietary sources and consumer tissues. We report the organic oxygen and hydrogen values of animal tissue from a porcine controlled dietary study. A complex mixture of fractionation and incorporation is revealed. In both deltaD and delta(18)O, differences in the absolute values and the amount of variation between and within consumer tissue are documented. Significant differences in deltaD and delta(18)O are observed between protein sources such as keratin and collagen.
