Insulin was discovered in 1921 by F. G. Banting and CH. Best in pancreatic extracts as a hypoglycemic substance. In 1926, J. Abel succeeded in crystallizing it, and in 1955, F. Sanger revealed its amino acid sequence. Insulin was the first protein whose amino acid sequence was determined. From [Chemistry]...Amino acid and protein chemistry, which was also started by Fisher, was developed with the introduction of paper chromatography and the invention of end-group analysis. Frederick Sanger (1918- ) succeeded in determining the amino acid sequence of insulin by making full use of the end-group labeling method with 2,4-dinitrofluorobenzene. This procedure was gradually automated, while the synthesis of polypeptides was also carried out with high selectivity by the solid-phase synthesis method of Merrifield and others. ... *Some of the terminology that mentions "Sanger, F." is listed below.

… インシュリンは1921年,バンティングF.G.BantingとベストC.H.Bestによって,膵臓の抽出物中から,血糖降下物質として見いだされた。次いで26年,エーベルJ.J.Abelが結晶化に成功,55年にサンガーF.Sangerがそのアミノ酸配列を明らかにした。インシュリンは,アミノ酸配列が決定された最初のタンパク質である。… 【化学】より…同じフィッシャーによって着手されたアミノ酸とタンパク質の化学は,ペーパークロマトグラフィーの導入と末端基分析のくふうによって発展した。サンガーFrederick Sanger(1918‐ )は2,4‐ジニトロフルオロベンゼンによる末端基標識法を駆使してインシュリンのアミノ酸配列順序の決定に成功した。この手続はしだいに自動化される一方,ポリペプチドの合成もメリフィールドR.B.Merrifieldらの固相合成法によって高度に選択的に行われるようになった。… ※「Sanger,F.」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
