Abstract
1. 1. The distribution of radiolabel from L-leucine [ 14C-UL] and D-glucose [ 14C-UL] was measured in the sea star Asterias rubens at 1, 6 and 24 hr after oral administration. 2. 2. Incorporation of the label from both compounds was observed in pyloric caeca, coelomocytes and ovaries even after an incubation time of 1 hr. 3. 3. Highest incorporation from both precursors was found in proteins, while substantial radioactivity was present in the amino acids, organic acids and neutral components. Lipids were hardly labelled from leucine and only slightly from glucose. 4. 4. Radioactivity in proteins and lipids increased with increasing incubation time. No significant differences were found in the distribution patterns of radiolabel during the reproductive cycle. 5. 5. The data obtained are discussed in terms of current knowledge on the translocation of nutrients in echinoderms.
