trypsin

Trypsin（胰蛋白酶）是英語名詞，音標為/ˈtrɪp.sɪn/，指脊椎動物胰腺分泌的絲氨酸蛋白酶，功能為催化蛋白質水解為小肽，以酶原形態（trypsinogen）分泌，經腸道激活後參與消化。該酶具有底物特異性，選擇性切割精氨酸或賴氨酸羧基端的肽鍵，其抑制劑（如大豆胰蛋白酶抑制劑）在生物醫學領域有重要研究價值。

1876年德國生理學家威廉·屈內首次分離並命名該酶。20世紀研究發現其通過激活消化酶級聯反應維持蛋白質代謝，並在病毒複製、腫瘤轉移中起調控作用。現代生物技術中廣泛用於細胞培養的組織消解，其結晶形態（trypsin crystallized）及外用製劑（trypsin for external use）已套用於臨床與實驗室。
