Ludwig Karl Martin Leonhard Albrecht Kossel (16 September 1853 – 5 July 1927) was a German biochemist and pioneer in the study of genetics. He was awarded the Nobel Prize for Physiology or Medicine in 1910 for his work in determining the chemical composition of nucleic acids, the genetic substance of biological cells. Kossel isolated and described the five organic compounds that are present in nucleic acid: adenine, cytosine, guanine, thymine, and uracil. These compounds were later shown to be nucleobases, and are key in the formation of DNA and RNA, the genetic material found in all living cells. Kossel was an important influence on and collaborator with other important researchers in biochemistry, including Henry Drysdale Dakin, Friedrich Miescher, Edwin B. Hart, and his professor and mentor, Felix Hoppe-Seyler. Kossel was editor of the Zeitschrift für Physiologische Chemie (Journal of Physiological Chemistry) from 1895 until his death. Kossel also conducted important research into the composition of protein, and his research predicted the discovery of the polypeptide nature of the protein molecule. The Albrecht Kossel Institute for Neuroregeneration at the University of Rostock is named in his honor. ==Early life and education== Kossel was born in Rostock, Germany as the son of the merchant and Prussian consul Albrecht Karl Ludwig Enoch Kossel and his wife Clara Jeppe Kossel. As a youth, Kossel attended the Gymnasium at Rostock, where he evidenced substantial interest in chemistry and botany.〔 In 1872, Kossel attended the University of Strassburg to study medicine. He studied under Felix Hoppe-Seyler, who was head of the department of biochemistry, the only such institution in Germany at the time. He attended lectures by Anton de Bary, Waldeyer, August Kundt, and Baeyer. He completed his studies at University of Rostock, and passed his German medical license exam in 1877.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Albrecht Kossel」の詳細全文を読む スポンサード リンク
