1. 課程名稱: 生物化學(醫技系醫檢組) 授課教師: 余兆松等十人 學分: 4 課程簡介: 生物由基本單位—細胞—所構成,而細胞則由數種生物大分子所構成.主要包括蛋白質,核酸,酯質及醣類.生物化學即以物理及化學的角度出發,來探討這些生物大分子的構成,性質及它們之間的交互作用,藉以初步了解生命運作的本質.本課程為大學部課程,透過不同專長教師講解指定教科書之內容,讓學生們對生物化學能有一全盤概念.除此以外,對於有關如何處理及分析生物大分子的技術亦會作初步的介紹,有興趣的同學亦可以此課程所學為出發點,進一步投入生物醫學實研究的領域中. (The course seeks to describe the structure, organization, and functions of living matter in molecular terms. Three principal areas will be covered: (1) the structural chemistry of the components of living matter and the relationship of biological function to chemical structure, (2) metabolism, the chemical reactions that occur in living matter, and (3) molecular genetics which provides introduction on how genetic material is replicated, recombined and maintained, how the genetic information is flowed from DNA to protein, and how these processes are regulated. ) 教學目標：幫助學生們了解生命現象的化學基礎,並建立生命現象如何運作的整體概念 教學方法：提供教學大綱講義,課堂講授,強調學習重點,期中期末考試評估學習成果 成績考核：課堂出席率與表現,三次期中考,一次期末考試 Textbook: Lehninger, “Principles of Biochemistry”, 3rd edition, 2000 Reference : Harper, “Biochemistry”, 25th edition, 2000.
