SUMMARY

A quantitative analysis of the iodoamino acids in whole dried parrot-fish thyroid gland was carried out by determination of stable 127I. Mono- and di-iodotyrosine together made up about half of the total iodoamino acids and thyroxine about a third to a half. The tri-iodothyronine content was low, about 5%. The total content of the acids increased with body weight, and there was an indication of a sex difference.
