Protein is one of the three macronutrients or “big nutrients” that make up the foods we eat—the other two are carbohydrate and fat. Protein, carbohydrate, and fat are essential nutrients, meaning they each play a vital role in the human body. Protein’s job is to make and repair our...
Proteins are made up of combinations of amino acids that contain the elements of carbon, hydrogen, nitrogen, oxygen and other elements enjoined in peptide bonds. Considered to be building blocks, proteins may also be antigens, enzymes, hormones or antibodies. Amino acids that make up protein ...
What is the importance of food webs in an ecosystem? What is the importance of zoology? How are buffers important to the functioning of living systems? What is the importance of pH in human body? Why is the bladder important? Why are flowering plants important?
stable, though liable to suffer a slight change in molecular character on treatmentnamely, the process of denaturation-which generally makes no appreciable difference in regard to utilization of the particular protein, although this physico-chemical change is of great assistance in cooking and baking....
The body’s metabolism produces toxic substances that have to be expelled from the body to prevent its own poisoning. All mammals, including humans, excrete urea as a result of protein metabolism. Humans expel an average of 30 grams per day of urea diluted in water through what is known as...
The number and mortality have fallen greatly since then and are still falling. Improved treatment has included the giving of more milk, especially dried milk, use of antibiotics, and better hygiene. The optimum amount of protein for such cases appeared to be from 6 to 8 g. per kg...关键...

The importance of ribosome production, and the 5S RNP–MDM2 pathway, in health and disease Ribosomes are abundant, large RNA鈥損rotein complexes that are the source of all protein synthesis in the cell. The production of ribosomes is an extremely... A Pelava,C Schneider,NJ Watkins - 《Bi...
Selenium is an essential trace element for the human body with a significant antioxidant effect. Selenium deficiency and excess are both detrimental for proper functioning of the human body. The possible association between selenium deficiency and acute or chronic renal disease, along with their complic...
Contribution of plasma proteins to the vitreous of the rat The extent of plasma proteins in the vitreous humor of the rat was determined. Disc gel electrophoresis of the soluble proteins of the rat vitreous humor showed many protein bands, but most of the bands did not coincide with those of...
