Bomb Carbon as a Tracer of Dietary Carbon Sources in Omnivorous Mammals

From the 17th International Radiocarbon Conference held in Jerusalem, Israel, June 18-23, 2000.We have isolated amino acid groups from modern bone hydrolysates and compared their relative ∆14C value to assess the carbon contribution of diet to the overall radiocarbon signal in bone. We find that both essential and non-essential amino acids may produce widely varying 14C, relative to other amino acid groups in the hydrolysate and to the original whole bone protein. We hypothesize that the 14C variations in non-essential amino acids may be due to metabolic effects that utilize essential amino acid carbon skeletons in the creation of non-essential amino acids.The Radiocarbon archives are made available by Radiocarbon and the University of Arizona Libraries.
