Organic chemist. Born in Tokyo. After graduating from the First High School, he graduated from the Department of Applied Chemistry at Tokyo Imperial University in 1901 (Meiji 34). In the same year, he joined the Tokyo Industrial Research Institute, where he devoted his life to the study of fats and oils. He is considered the father of fat and oil chemistry in Japan. He published 172 research papers both in Japan and abroad, and all but one of them were about fats and oils. His famous discovery of squalene C 30 H 50 (1916) is noteworthy as the first discovery of a hydrocarbon in the animal kingdom. He received a doctorate in engineering in 1915 (Taisho 4) and the Imperial Prize in 1920. He discovered 13 species, including sardine acid. Among his wide-ranging hobbies, his most notable interest was mountain climbing, and he was one of the founders of the Japan Alpine Club. Among the 59 species of plants he collected from Mount Ho-o in the Southern Alps, some were unknown to the academic world, including one species of Campanulaceae that he named Ho-o-shajin. He also studied the oils from the seeds of alpine plants. [Yojiro Tsuzuki] [Reference item] | |Source: Shogakukan Encyclopedia Nipponica About Encyclopedia Nipponica Information | Legend |
有機化学者。東京生まれ。第一高等学校を経て、1901年(明治34)東京帝国大学応用化学科を卒業、同年東京工業試験所に入り、終生同所で油脂の研究に没頭した。日本における油脂化学の父である。研究報告は内外に発表したもの172編、うち1編を除いてはことごとく油脂に関するものである。有名なスクアレンC30H50の発見(1916)は動物界における炭化水素の最初の発見として注目に値する。1915年(大正4)工学博士、1920年恩賜賞を受賞した。彼の発見したものはイワシ酸ほか13種に及ぶ。広い趣味中、特筆すべきものは登山で、日本山岳会設立者の一人であり、南アルプスの鳳凰(ほうおう)山で採取した植物59種のなかには学界未知のものもあり、そのなかのキキョウ科の1種はホウオウシャジンと命名された。高山植物の種子の油も研究している。 [都築洋次郎] [参照項目] | |出典 小学館 日本大百科全書(ニッポニカ)日本大百科全書(ニッポニカ)について 情報 | 凡例 |
