II. Reading Phytopharmacy Phytopharmacy is the study of the plants that are used as drugs and the drugs that are isolated from plants. Medicinal plants are important for many reasons: they provide us with natural drugs, activeconstituents and intermediates for semi-synthetic drugs. Nature produces an astonishing variety of complex phytoconstituents which embrace all fields of pharmacological action. ![]() Plants are constantly metabolising, both breaking down preformed molecules and building new ones at the same time. Besides their own essential principles, the so-called primary plant products, plants produce other principles, which apparently do not have any definite biological function. These are the so-called secondary products. Their biological function is often discussed but the fact is that many of them have a special importance outside the plant because of their pharmacological action. Plants that give drugs have both active and inactive substances. The inactive substances include cellular structures and pharmacological inactive compounds. A plant seldom has only one active principle. Often it produces a series of structurally related compounds having similar pharmacological properties. In this case it is possible to use either the total principles or the isolated and chemically pure compounds. This situation may be complicated when there are synergistic or antagonistic principles or substances with other pharmacological effects in the plant at the same time. Also the inactive compounds may interfere with the action of the active ones or they may be their precursors. The inactive principles may alter the activity of the drug by physical means, for example, they may act as co-solvents of the active compounds or delay their absorption or diffusion in the organism. Drugs in general arise from a heterogeneous population of individual plants living under a variety of conditions. Therefore, it is not surprising that their quality is affected by their variability, which is due to two main causes: intrinsic (endogenous) factors inherent to the genetic constitution and independent of external conditions; and extrinsic (exogenous) factors dependent on the ecological and environmental conditions in which the plant grows. Sometimes intrinsic factors are latent in the plant and only appear as a response to the appropriate external factors. III. Language development 1.

2. Read and translate the text. CHEMISTRY Chemistry is the study of substances. Chemists investigate properties of the substances that make up the universe and how these substances behave under different conditions. They attempt to explain the behavior of a substance in terms of its structure and composition. Chemists also seek to understand chemical changes. These changes involve alterations in the chemical makeup of a substance. The com combination of iron with oxygen from the air forming rust is a chemical change. Substances may also go through physical changes without altering their chemical makeup. Water changes physically but not chemically when it freezes. Chemists have learned much about the chemical substances and processes that occur in the nature and have created many useful substances that do not occur naturally, so they have greatly improved people’s lives. ![]() Chemistry studies many substances. Substances differ greatly in properties, structure, and composition. The methods chemists use and the questions they attempt to answer also differ greatly. The most basic chemical substances are the chemical elements. They are the building blocks of all other substances. Each chemical element is made up of only one kind of atom. There are 91 elements known to exist on the Earth. Additional 20 elements have been produced artificially. Electrical forces at the atomic level create chemical bonds that join two or more atoms together, forming molecules. Some molecules consist of atoms of a single element. When atoms of two or more different elements bond together, they form a chemical compound. Water is a compound of two hydrogen atoms and one oxygen atom. Compounds are formed or broken down by means of chemical reactions. All chemical reactions involve formation or destruction of chemical bonds. Chemistry comprises the following sciences. Analytical chemistry determines the identity and quantity of each element or compound present in a substance. Qualitative analysis is concerned with identifying the kinds of elements or compounds in a sample. Quantitative analysis indicates the amounts of the elements present. The techniques of analytical chemistry include the use of the spectroscope, mass spectrograph, X-ray tube, ultraviolet fluorescence, and radioisotopes. Biochemistry is the study of the chemical composition of living matter and of the chemical processes that occur in living organisms. This field is particularly important in agriculture, biology, bacteriology, pharmacology, medicinc, and dentistry. Chemical engineering is a combination of chemistry and engineering that develops or improves industrial processes for making commercial amounts of desirable chemicals that have been produced only in small quantities or in the laboratory. Colloid chemistry is the study of the behavior of matter particles that are larger than ordinary molecules but smaller than objects that can be seen with the best optical microscope. Particles in this size range (10 to 2.000 A in diameter) have many unique properties. The tools used in this field include the ultracentrifuge, ultramicroscope, and electron microscope. Electrochemistry is the study of chemical reactions that are produced by or produce an electric current. Also studied are the electrical conductivity of solutions and the phenomena that occur at electrodes application. Electrochemistry provides methods for chemical analysis and production of chemicals by electrical means. Inorganic chemistry is the study of all elements and compounds that do not contain carbon. These include metals, halogens, and alkalies. Nuclear chemistry is the study of radioactivity, atomic nucleus, and nuclear reactions, and the development of applications for radioactive isotopes in medicine and industry. Organic chemistry is the study of carbon and its compounds. Carbon compounds account for about 96 percent (about six and one-half million) of all known compounds. Among the carbon compounds studied by organic chcmists arc plant and animal tissues, petroleum, carbohydrates, proteins, plastics, and rubber. Physical chemistry is the application of physical methods to the study of chemical problems. Included in this field are atomic and molecular structure; theory of reaction rates; mechanism of reactions; chemical equilibriums; energy changes in reactions; theories of solids, liquids, gases, plasmas, and solutions; electrochemistry; radioactivity.

III. Read and translate the text. ORGANIC CHEMISTRY Organic chemistry is the chemistry of the compounds of carbon. There are many such compounds - over a half million different organic compounds have been described in the chemical literature. The simplest, organic compounds are the hydrocarbons. The carbon atom possesses the property of being able to form either chains or rings by joining up a number of similar carbon atoms together. The carbon atom is tetravalent (lour bonds) whereby other atoms can be joined to it. A feature of organic chemistry is that the number of other elements involved is small: hydrogen, oxygen and nitrogen are by far the most common. The three biggest classes of the organic compounds are proteins, carbohydrates and lipids. Proteins are made of many amino acids linked together. Amino acids are compounds having both the properties of amines and acids. There ate many naturally occurring amino acids. The substances are found either free as components of plant or animal tissues or as a product of protein hydrolysis. Several of them are essential in human nutrition. The amino acids essential for human equilibrium are: isoleucine, leucine, lysine, methionine, phenylanine, iheonine, and valine. Histidine is required by infants. Proteins are among the .most important substances in plants and animals. Proteins occur as separate molecules or as reticular constituents of cells. Proteins are separated into groups based chiefly on physical properties (solubility, coagulation, precipitation). These groups are: albumins, globulins, prolamines, nucleo-proteins, phosphoropro-teins (casein in milk), albuminoids, chromoproteins (color of hemoglobin). The human body contains different proteins. The blood, hair fingernails, skin, tendon and muscle fibers consist mostly of protein. Plant and animal food contains proteins (meat, eggs, milk and cheese, cereals and nuts). Special enzymes convert proteins into simple amino acids so that the body can use them. Carbohydrates occur widely in nature. The most important carbohydrates are sugars, starches, and celluloses. The carbohydrates are classified according to the number of carbon, atoms in the molecule: monosaccharides-pentoses (xylose, ribose), hexoses (glucose, galactose, fructose), disaccharides (sucrose, maltose and lactose) and polysaccharides (cellulose, starch, glycogen and inulin). A common simple sugar is glucose, a primary product of photosynthesis, present in every plant cell. Jt occurs in many fruits and is present in the blood of animals. Fructose, the so-called fruit sugar, is present in fruits. Fructose1 condenses to form inulin. Inulin is an important food reserve in some plants. Ordinary sugar (cane-sugar, beet-sugar) is sucrose. The molecules of it are found in plants (wheat, maize, barley, carrots, sugar beet), in most fruits and leaves of many plants. Important polysaccharides include, starch, glycogen and cellulose. Starch is the most common food reserve material in plants (in the seeds, tubers, and in the leaves, as a temporary product of photosynthesis). When a drop of potassium iodide solution is placed on a part of the plant, the granules of starch become blue. Starch is an important constituent of foods (potatoes, wheat and others). Glycogen (animal starch) is a, substance similar to starch occurring in the blood and internal organs, especially liver, of animals. It serves as a reservoir of carbohydrates. Whenever the .concentration of glucose in blood becomes low, glycogen is rapidly hydrolyzed into glucose. Lipids are any of a diverse class .of organic compounds, found, in all living things that are greasy and insoluble in water. One of the three large classes of substances hi foods and living ceils, lipids contain more than twice as much energy (calories) per unit of weight as the other two (proteins and carbohydrates). They include the fats and edible oils (e.g. butter, olive oil, corn oil), which are primarily triglycerides; phospholipids (e.g. lecithin), which are important in cell structure and metabolism; waxes of animal or plant origin; and sphingolipids, complex substances found in various tissues of the brain and nervous system.
