A heptadecapeptide has been isolated from a side fraction of beta-MSH in an acid acetone extract of the pituitary of the salmon, Oncorhynchus keta. The sequence analysis revealed the peptide to be another form of salmon beta-MSH with following primary structure; H-Asp-Gly-Ser-Tyr-Arg-Met-Gly-His-Phe-Arg-Trp-Gly-Ser-Pro-Thr-Ala-Ile-OH. The findings of two distinctive beta-MSHs as well as two endorphins as reported previously in the pituitary extract suggest that the teleost pituitary may secrete two different precursor molecules, beta-LPH, and thus also higher molecular weight precursors.
从大麻哈鱼（Oncorhynchus keta）脑垂体的酸性丙酮提取物中β-MSH的一个侧馏分中分离出一种十七肽。序列分析表明该肽是鲑鱼β-MSH的另一种形式，其一级结构如下：H-Asp-Gly-Ser-Tyr-Arg-Met-Gly-His-Phe-Arg-Trp-Gly-Ser-Pro-Thr-Ala-Ile-OH。垂体提取物中先前报道的两种不同的β-MSH以及两种内啡肽的发现表明，硬骨鱼脑垂体可能分泌两种不同的前体分子，即β-LPH，因此也分泌更高分子量的前体。
