Biochemistry in broad terms is the study of the chemical composition of the living matter and the biochemical processes that underlie life activities during growth and maintenance. This article is an attempt to explore the metamorphosis of biochemistry from a pupa entwined in its own cocoon to a vibrantly colored phenomenon. Studies pertaining to this discipline of science began with Biochemistry interfaces with biology and chemistry even before nineteenth century with studies concerned with the chemical processes that take place within living cells. Modern biochemistry developed out of and largely came to replace what in the nineteenth and early twentieth centuries was called physiological chemistry, which dealt more with extra cellular chemistry, such as the chemistry of digestion and of body fluids. The name Biochemistry was coined in 1903 by a German chemist named Carl Neuber. However, work in this very living, aspect of chemistry had started much earlier. Claude Bernard is accredited with the Sirehood of Biochemistry. During the later part of the nineteenth century eminent scientists contributed a great deal to the elucidation of the chemistry of fats, proteins and carbohydrates. At this period some very fundamental aspects of enzymology were under close scrutiny. Study of nucleic acid is central to the knowledge of life but its fusion with biochemistry started with works of Fredrick Sanger and Har Gobind Khurana. Their experiments involved a subtle bland of enzymology and chemistry that few would have thought possible to combine. The scientists were busy removing the mist that was mitigating the light of knowledge but they still lacked an insight into the cell. In 1990's research turned to finding the structural details of cell. The field of molecular biochemistry was also progressing at an almost unstoppable speed having expanded its horizons beyond human imagination with the introduction of PCR, creating waves of appreciation from every field of medicine and then coming out of the lab to help establish better therapies for various diseases by introduction of gene therapy. Biochemistry has promises to the world of science in development of new path-breaking research and coming times would surely prove these promises to be fulfilled.
广义而言,生物化学是对生命物质的化学组成以及生长和维持生命活动背后的生物化学过程的研究。本文旨在探索生物化学从一个困在自己茧中的蛹到一个色彩斑斓的现象的蜕变。甚至在19世纪之前,与这门科学相关的研究就开始了,当时生物化学与生物学和化学相互交叉,涉及对活细胞内发生的化学过程的研究。现代生物化学从19世纪和20世纪初被称为生理化学的领域发展而来,并在很大程度上取代了它,生理化学更多地涉及细胞外化学,如消化和体液的化学。“生物化学”这个名字是1903年由一位名叫卡尔·纽伯的德国化学家创造的。然而,这一非常活跃的化学领域的工作早在更早的时候就开始了。克劳德·伯纳德被誉为生物化学之父。在19世纪后期,杰出的科学家们为阐明脂肪、蛋白质和碳水化合物的化学做出了巨大贡献。在这个时期,酶学的一些非常基本的方面受到了密切关注。对核酸的研究是生命知识的核心,但它与生物化学的融合始于弗雷德里克·桑格和哈·戈宾德·科拉纳的工作。他们的实验涉及酶学和化学的巧妙结合,很少有人会想到这两者可以结合。科学家们忙于驱散遮蔽知识之光的迷雾,但他们仍然缺乏对细胞的洞察力。在20世纪90年代,研究转向寻找细胞的结构细节。分子生物化学领域也在以几乎不可阻挡的速度发展,随着聚合酶链反应(PCR)的引入,其视野扩展到超出人类想象的范围,在医学的各个领域引起了一阵赞赏,然后走出实验室,通过引入基因疗法来帮助建立针对各种疾病的更好疗法。生物化学在新的开创性研究发展方面对科学界有着承诺,未来肯定会证明这些承诺会得以实现。
