aProtein has a large number of important functions in the human body—and in fact, the human body is about 45% protein. It’s an essential macromolecule without which our bodies would be unable to repair, regulate, or protect themselves. 蛋白质有很大数量的重要作用在人身体和实际上,人体是...
aAlong with carbohydrates, fats and nucleic acids, proteins are the \"building blocks of life.\" Learn about the functions of protein in the human body to find out why these molecules are so important. 与碳水化合物、油脂和核酸一起,蛋白质是\ “生活积木。\”得知蛋白质的作用在人体发现为什么...
Each contains the instructions for building a protein (蛋白),so those that became more active produced more proteins 一 changing the chemistry of the body. Meanwhile the natural body clock was disturbed — some genes naturally get weak in activity through the day, but this effect was eased (...
Protein is synthesized in the liver from amino acids that is absorbed from the intestines. Excessive amino acids will be converted into urea and excreted from the body. 从肠道吸收的氨基酸在肝脏合成为蛋白质。过多的氨基酸会转化成尿素并排出体外。 The liver is also important in the metabolism of f...
The asymmetry becomes morphologically obvious in the turning of the embryo and in the of the heart, the gut and other visceral organs. In the chick embryo, a signalling pathway for the specification of the left body side was demonstrated. Here, Sonic hedgehog (Shh) protein is the first ...
RNA helicases constitute a large family of proteins with functions in all aspects of RNA metabolism. RNA helicases can have a variety of biochemical effects, such as unwinding or annealing RNA molecules, clamping protein complexes on RNA or remodelling ribonucleoprotein complexes. Transcriptome analyses...
Although mucus is important in many places in the body, for most of us, its presence is most obvious in the nose and the respiratory tract. People may not deliberately look at their nasal mucus, or snot, but they may accidentally notice that it occasionally has an unusual appearance. The ...

Amino acids and proteins in relation to the nutrition of elderly people. Aspects of body protein and amino acid metabolism during ageing in man are reviewed. Due to a decrease in skeletal muscle mass with ageing, total body prot... Young,R V. - 《Age & Ageing》 被引量: 127发表: 1990...
In natural proteins, structured loops have central roles in molecular recognition, signal transduction and enzyme catalysis. However, because of the intrinsic flexibility and irregularity of loop regions, organizing multiple structured loops at protein functional sites has been very difficult to achieve by...
