  1. . Protein viruses
    3.1. Amino Acid Composition of Viral Proteins The protein of all viruses studied so far is made up of ordinary amino acids belonging to the natural L-series. D-amino acids in the composition of viral particles not found. The ratio of amino acids in viral proteins is quite close to that in animal, bacteria and plant proteins. Viral proteins do not usually contain large amounts
  2. PROTEINS AND THEIR MEANING IN FOOD
    * Proteins are indispensable substances necessary for the life, growth and development of the body. The lack of protein in the body leads to the development of alimentary (from the Latin. Alimentum - food) diseases. Proteins are used as plastic material for building various tissues and cells of the body, as well as hormones, enzymes, antibodies and specific proteins. Proteins - a necessary background for
  3. GENES AND PROTEINS
    After years of research into sickle cell anemia (anemia), it has become obvious that a mutation in 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-Gram discovered that normal and
  4. Squirrels
    The importance of correctly addressing the issue of protein nutritional indices 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 human life activity and its efficiency. At the same time, the organism, possessing insignificant reserves of protein, is not able to
  5. Acute phase proteins
    The acute phase response is characterized by a significant increase in the serum content of a number of proteins, which are called acute phase proteins (Table 2.4). In humans, these are C-reactive protein, serum amyloid A, fibrinogen, haptoglobin, a-1-antitrypsin, cc-1-antihimotrypsin, etc. - only about 30 proteins. Table 2.4 The degree of increase in the content of proteins of the acute phase in
  6. Biologically active proteins of influenza virus. Hemagglutinin
    I. T. SCHULZE (I. T. SCHULZE) I. INTRODUCTION TOT The fact that influenza viruses have the ability to agglutinate red blood cells has played a large role in the development of our ideas about these infectious particles. Hemagglutination has proven to be an extremely convenient method for identifying, purifying and determining the concentration of viruses. In addition, since (the discovery of the phenomenon of hemagglutinitis 35 years ago
  7. Biologically active proteins of influenza virus. Neuraminidase
    D. BOOKER and P. PALESE (BUCHER, P. PALESE) I. INTRODUCTION The existence of neuraminidase for the first time suggested the existence of neuraminidase in the now classic work of Hirst (1942). He found that if the erythrocytes agglutinated in the presence of the influenza virus deagglutinate, then when a new virus is added to them, they are again not capable of agglutination. However, the eluted virus does not

  9. Biologically active proteins of influenza virus. Transcriptase activity in influenza cells and virions
    RV OIMPSON and VD BIN (RW SIMPSON, WJ BEAN, JR.) I. INTRODUCTION This chapter “deals with a rather new section in the biology of the influenza virus, and therefore most of the information is fragmentary in its composition C a large number of outstanding issues. The basic statement on which this chapter is based is that mycoviruses are negative genome viruses.
  10. Monoclonal T-cell receptors (mTRC) are the basis for the creation of a new class of “drug-killer” of cancer cells
    The surface of the living cell membrane is littered with proteins, some of which are associated with carbohydrates. Among them are receptor proteins and marker proteins. The former are used by the cell to exchange information between cells, and the latter serve to identify cells. On the surface of the cancer stem cell there are proteins that are not found on a normal cell of this type. These are fetal marker proteins and altered proteins.
  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. All variety of proteins is provided with 20 amino acids. Some of them are synthesized in the body and are called interchangeable, others, not synthesized, must in
  12. Protein chip for the diagnosis of cancer cells of the primary tumor and micrometastases in the patient’s serum
    The second way is the early diagnosis 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 the proteins it synthesizes. These proteins are the product of "breakdowns" in the genetic material of a normal cell, which turned it into cancer. Their presence is a sign that the gene or genes that cause the degeneration of a normal cell, has begun its
  13. CHEMICAL COMPOSITION
    The chemical composition of meat is very complex and depends on the type of animal, age, sex, fatness, level of feeding and other factors. Significantly changes the chemical composition of animal meat in severe pathological conditions. The chemical composition of meat includes: water, proteins, fats and lipids, carbohydrates, extractives, minerals, vitamins, enzymes and hormones. Chemical composition
  14. Signal peptide G. Blobel, controlling the transport of proteins and their localization inside the cell, 1 - meaning for oncology
    In a cell of any type there are many divisions - organelles: the nucleus, mitochondria, etc. They are surrounded by membranes, just like the cell itself. Each cell has about a billion protein molecules, i.e. proteins of different types. A cell's DNA is a “drawing” of a cell, and proteins are the builders of a cell. Before cell division, the set of all proteins for the daughter cells is doubled in it. Proteins are characterized by diversity.
  15. "Ubiquitin-mediated cleavage" of "unwanted" proteins in the cell - meaning for oncology
    Each human cell contains many different proteins. Their total number in the cell while no one knows. The numbers of proteins in a 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 the cell, enzymes regulate chemical reactions, receptor proteins 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 food substances. Consist of amino acids, 22 amino acids are registered. Consist of: carbon, hydrogen, oxygen, phosphorus, sulfur, nitrogen. The role of protein is predominantly plastic, is a building material for the formation of new tissues and the replacement of dead cellular structures. Replaceable amino acids: glycine, arginine,
  17. Kilburn, ED. Flu and flu viruses (1978), 1978

The structure of the influenza virus. Biologically active proteins of influenza virus. Hemagglutinin. Biologically active proteins of influenza virus. Neuraminidase. Transcriptase activity in influenza cells and virions. Ribonucleic acid viruses
  18. Metabolism and energy
    The main feature of a living organism is metabolism and energy. In the body, there are continuous plastic growth processes, the formation of complex substances that make up the cells and tissues. In parallel, the reverse process of destruction occurs. Every human activity is associated with the expenditure of energy. The normal course of these processes requires complex organic substances, as they are
  19. The structure and function of the protein
    Proteins play a crucial role in the life of any organism. The diversity 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. MAJOR NUTRIENTS, MINERALS, MICROELEMENTS AND THEIR SIGNIFICANCE IN NORM AND PATHOLOGY
    There are 6 main groups of nutrients, 3 of which provide the body with energy - it is proteins, fats and carbohydrates. Other nutrients - vitamins, minerals and water - are non-energetic. In the body, proteins, fats and carbohydrates are broken down to form energy. The amount of energy released from 1 g of a substance is called the energy
