Radioactivity (expressed as counts per minute per milligram in nil. extract or brei) recovered in the alcohol-soluble (solid curve) and alcohol- insoluble (dashed curve, parenthetical figures on ordinate) fractions of Ophiactis adapted to various salinities. The animals were exposed to glycine-C14 in their respective media fur 30 minutes; n is 10 in all cases. Vertical bars represent standard deviations. alcohol-soluble and the alcohol-insoluble fractions was determined for each animal. Measurements were made of the free amino acid pool in each group. A control group which was kept in 100% sea water under otherwise comparable conditions was sampled during the same period. Figure 4 presents the change in the free amino acid pool during the ten-day period for the two groups. Figure 5 presents.
