title: Degradation of hypothalamic hormones.
abstract: The enzymatic fragmentation of TRH (pyroGlu-His-Pro-NH2) by serum, hypothalamic and hypophyseal tissue was investigated. As primary cleavage product only His-Pro-NH2 was detected when TRH was incubated with serum while with the tissue preparations the formation of His-Pro-NH2, deamido-TRH and prolineamide could be detected as enzymatically formed primary fragments.
