Proteins.

  1. . Virus proteins
    3.1. Amino acid composition of viral proteins The protein of all the viruses studied to date is constructed from ordinary amino acids belonging to the natural L-series. D-amino acids in the composition of virus particles were not found. The ratio of amino acids in viral proteins is close enough to that in proteins of animals, bacteria and plants. Viral proteins do not usually contain a large amount
  2. PROTEINS AND THEIR IMPORTANCE IN NUTRITION
    * Proteins are irreplaceable substances necessary for life, growth and development of the body. Insufficiency of protein in the body leads to the development of alimentary (from Latin alimentum - food) diseases. Proteins are used as a plastic material for building various tissues and body cells, as well as hormones, enzymes, antibodies and specific proteins. Proteins are a necessary background for
  3. GENES AND PROTEINS
    After many years of research on sickle cell anemia (anemia), it became apparent that the mutation of a particular gene leads to changes in the chemical structure of the hemoglobin molecule. The main type of adult hemoglobin consists of four polypeptide (protein) chains: two identical? -Chains and two identical? -Chains (? 2? 2). In 1957 V. In-grem discovered that the normal and
  4. Proteins
    The importance of a correct solution of the problem of protein nutrition indisputability is indisputable, since the sufficiency of protein in the diet and its high quality make it possible to create optimal conditions for the internal environment necessary for growth, development, normal life activity and human performance. At the same time, the organism, possessing insignificant reserves of protein, is not able to stay for a long time
  5. Proteins of acute phase
    The acute phase response is characterized by a significant increase in the serum levels of a number of proteins, which are called acute phase proteins (Table 2.4). In humans, C-reactive protein, serum amyloid A, fibrinogen, haptoglobin, a-1-antitrypsin, cc-1-antichymotrypsin, and others are counted among them - about 30 proteins in all. Table 2.4 The degree of increase in the content of acute phase proteins in
  6. Biologically active proteins of the influenza virus. Hemagglutinin
    I. T. SCHULZE I. INTRODUCTION The fact that influenza viruses have the ability to agglutinate erythrocytes has played a big role in the development of our ideas about these infectious particles. Hemagglutination proved to be an extremely convenient method for identification, purification and determination of the concentration of viruses. In addition, from the time of detection of the haemagglutinase phenomenon 35 years ago
  7. Biologically active proteins of the influenza virus. Neuraminidase
    D. BOUKER and P. PALEISE (BUCHER, P. PALESE) I. INTRODUCTION The existence of neuraminidase was first suggested by Hirst (1942), which has now become a classic work. He found that if agglutinated in the presence of flu virus, erythrocytes deagglutinate, then adding a new virus to them again they are not capable of agglutination. However, however, the eluted virus does not

    LEGS OF THE PONETVOLITE, EXPLOSIONS AND PRECURSORS, OR THE BEHAVIOR STEREOTYPES IN THE RECEPTION
  9. Biologically active proteins of the influenza virus. Activity of transcriptase in cells and influenza virions
    R. V. OIMPSON and VD BIN (RW SIMPSON, WJ BEAN, JR.) I. INTRODUCTION This chapter is "consecrated to a rather new section in the biology of the influenza virus, and therefore most of the information is fragmentary in its composition, a large number of outstanding issues. The main statement on which this chapter is based is that mycooviruses are viruses with a negative genome
  10. Monoclonal T-cell receptors (mTCR) - the basis for creating a new class of "killer drug" of cancer cells
    The surface of the membrane of a living cell is strewn with proteins, some of them are bound to carbohydrates. Among them - protein-receptors and protein-markers. The former are used by the cell to exchange information between cells, while the latter serve to identify the cells. On the surface of the cancerous stem cell there are proteins that are not present on a normal cell of this type. These are fetal protein markers and proteins of altered
  11. Nutrients
    Proteins Proteins are one of the main components of food and perform a number of functions: plastic, catalytic, hormonal, tranport, etc. From a chemical point of view, proteins are polymers consisting of amino acids. The whole variety of proteins is provided by 20 amino acids. Some of them are synthesized in the body and are called interchangeable, others not synthesized should
  12. Protein chip for diagnosis of cancer cells of the primary tumor and micrometastases by the patient's blood serum
    The second way of early detection of cancer cells by proteins on the surface of cancer cells. A cancer cell differs from a normal cell of the same type in the composition of proteins synthesized by it. These proteins are a product of "breakages" in the genetic material of a normal cell, which turned it into a cancer cell. Their presence is a sign that the gene or genes causing the degeneration of a normal cell began
  13. CHEMICAL COMPOSITION
    The chemical composition of the meat is very complex and depends on the type of animal, age, sex, fatness, level of feeding and other factors. The chemical composition of meat of animals under severe pathological conditions significantly changes. The chemical composition of meat includes: water, proteins, fats and lipids, carbohydrates, extractives, minerals, vitamins, enzymes and hormones. Chemical composition
  14. G. Blobel's signal peptide, which controls the transport of proteins and their localization within the cell, 1 - the value for oncology
    In a cell of any type, there are many departments - organelles: nucleus, mitochondria, etc. They are surrounded by membranes, like the cell itself. In each cell there are about a billion protein molecules, i.e. proteins of different types. The DNA of the cell is the "drawing" of the cell construction, and the proteins are the "builders" of the cell. Before dividing the cell, it doubles the set of all proteins for the daughter cells. The proteins are characterized by a variety of
  15. "Ubiquitin-mediated cleavage" of "unnecessary" proteins in a cell - a value for oncology
    Each human cell contains many different proteins. No one knows their total number in the cage. The numbers of proteins in the cell are called different: one hundred thousand or more. Proteins in a cell of each type perform different and very important functions: globulins and other proteins - build a cell, enzymes - regulate chemical reactions, protein receptors and ligand proteins to them are important for transmission
  16. Hygienic characteristics of the protein
    Proteins are high-molecular nitrogen-containing substances and the most important nutrients. They consist of amino acids, 22 amino acids are registered. They consist of: carbon, hydrogen, oxygen, phosphorus, sulfur, nitrogen. The role of the protein is predominantly plastic, it is a building material for the formation of new tissues and the compensation of dead cellular structures. Replaceable amino acids: glycine, arginine,

Structure of the influenza virus. Biologically active proteins of the influenza virus. Hemagglutinin. Biologically active proteins of the influenza virus. Neuraminidase.

  18. Metabolism and energy
    The main sign of a living organism is metabolism and energy. In the body, plastic processes of growth, formation of complex substances, which consist of cells and tissues, are continuously proceeding. In parallel, the reverse process of destruction occurs. Every activity of a person is connected with the expenditure of energy. The normal course of these processes requires complex organic substances, since they are
  19. Structure and functions of the protein
    Proteins play a vital role in the vital activity of any organism. The variety and complexity of living matter, in fact, reflect the diversity and complexity of the proteins themselves. Each protein has its own unique function, which is determined by its inherent structure and chemical properties. Some proteins are enzymes, i.e. catalysts of biochemical reactions in living organisms. Each
  20. MAIN NUTRITIVE SUBSTANCES, MINERALS, MICROELEMENTS AND THEIR SIGNIFICANCE IN NORM AND PATHOLOGY
    There are 6 main groups of nutrients, 3 of which provide the body with energy - these are proteins, fats and carbohydrates. Other nutrients - vitamins, minerals and water - are not energy substances. In the body, proteins, fats and carbohydrates are split into energy. The amount of energy released in this case from 1 g of the substance is called the energy
