This paper discusses the effect of the thermal denaturation on the structure,functions and enzymatic hydrolysis of proteins.

本文论述了热变性对蛋白质结构、功能性质以及酶解性质的影响，揭示了蛋白质热变性后理化性质的变化是其二级、三级或四级结构改变的结果，并讨论了其它因素对热变性的影响。

Denaturation A process that causes unfolding of the peptide chain of proteins or of the double helix of DNA.

变性：可以使蛋白质的多肽链或 DNA 的双螺旋解开的一个过程。

When most proteins are heated, they denature and lose their effectiveness.

多数的蛋白质在接受加热时，它们会变性，并且失去效用。

However, globular proteins that contain multiple disulfide bonds often must be heated longer at higher temperatures to denature them.

但是含多个二硫键的球蛋白却必须在更高的温度下加热更长的时间才能使之变性。

Proteins perform their function at a range of their growth temperature and excessively high or low temperature will make them denature and lose their function.

每个蛋白质都有最适宜发挥其功能的温度，过高或过低的温度都会使得蛋白质变性而丧失其功能。

However, the final temperature of processed meats could not sufficient to denature the main components of soy protein (7S and 11S), thereby limiting its interaction with muscle proteins.

然而当其应用到肉品加工过程中，大豆分离蛋白的主要成分(7S和11S)并不能表现出理想的结构变化，抑制肉品中的蛋白变性，导致大豆分离蛋白在应用上的局限性。

To detect the marks reflecting the liver functions as follows:①The marks to reflect the capability to synthesize proteins, TPROT, ALB, GLB;②The marks to reflect the injury of the liver cells: AST, ALT, CHE;③The marks to reflect the capability to egest the bile, excrect, and detoxicate: TBILI, DBILI, IBILI, TBA;④The enzymes to reflect the cholestasis: GGT, ALP. Results The results of both the morphological and the pathological studies showed that the degree of the liver cirrhosis was of the terminal stage.

肝功能指标：①反映肝细胞蛋白合成代谢功能的指标：总蛋白TPROT，白蛋白ALB，球蛋白GLB；②肝细胞受损的指标；谷草转氨酶AST，谷丙转氨酶ALT，胆碱脂酶CHE；③反映肝脏胆排泄、分泌及解毒功能的指标：总胆红素TBILI，直接胆红素DBILI，间接胆红素IBILI，总胆汁酸TBA；④胆汁淤积指示酶：谷氨酰转肽酶GGT，碱性磷酸酶ALP。

A typical PEST domain that exists in many known rapidly degraded proteins is found between amino acid position 128～140 of the deuced protein.

经GenBank查新证实它是一个全新的基因编码序列后，将该cDNA以EIF2B4的命名在GenBank登录（AF057699）。

In this review, we describe nuclear magnetic resonance techniques which are widely used to investigate inter-molecular interactions between proteins and diamagnetic/paramagnetic metal ions.

本文简要介绍目前国际上用NMR方法研究抗磁金属离子和顺磁金属离子与蛋白质相互作用的进展，并具体介绍了NMR方法在钙调蛋白、锌指蛋白、朊病毒蛋白等金属离子蛋白研究上的应用。

The result indicates the t-BHP or diamide both cause the mass loss about the membrane protein thiol in hepatocytes, the fast oxidization about glutathione in hepatocytes, the leakage of lactate dehydrodenase, but the level of t-BHP is larger than of diamide. In the aspect of lipid peroxidation, only the t-BHP produces apparent change. As to actin and tubulin, they both find fall-off and present time-dependency effects. The result in Confocal fluorescent microscope also show these two cytoskeletal proteins are related to cell blebbing, but they don''t play the same role during the porcess. Tubulin may be more important than actin. If the study predispose dithiothreitol before adding t-BHP or diamide, then the damage by the diamide is repressed, but just partly protection for the damage by t-BHP.

结果显示t-BHP或diamide均可造成细胞膜蛋白硫醇大量流失与胞内GSH快速氧化，亦显著导致乳酸去氢□渗漏，但t-BHP诱发的渗漏程度大於diamide；在脂质过氧化方面，则仅t-BHP处理组产生明显的脂质氧化情形；至於肌动蛋白与管蛋白单体均可见减少且呈现时间依赖效应；在雷射共轭焦萤光显微镜观察中，亦显现这两种架构蛋白与细胞膜起泡有关，但两者在小泡生成的过程中扮演的角色并不完成相同，可能管蛋白较肌动蛋白重要；如果细胞在t-BHP或diamide加入前预先以dithiothreitol处理，则diamide 所造成的伤害显著的受到抑制，但DTT对t-BHP所诱发的伤害则仅有部分保护效果。
