Abstract

1. 1. Amino acid metabolism in mantle tissue from the brachiopod T. transversa and the bivalve mollusc C. hastata was determined in vitro by measuring CO 2 evolved from 14C labeled amino acids. 2. 2. Of the 19 amino acids assayed, the brachiopod metabolized 11 and the bivalve mollusc metabolized 14 in different rank orders. 3. 3. Aspartic acid ranked first for the brachiopod and accounted for 52% of the total CO 2 evolved, whilst valine ranked first for the bivalve mollusc and accounted for 29%. 4. 4. The brachiopod produced about 38 μmol CO 2/g/hr from the amino acids metabolized, whereas the bivalve mollusc produced about 138 μmol CO 2/g/hr. 5. 5. Results suggest that T. transversa and C. hastata, sympatric along the Pacific northwest coast, utilize different amino acids at different rates.
