Bibcode : Natur. doi : PMID Future Medicinal Chemistry. PMC The European Agency for the Evaluation of Medicinal Products. Retrieved 26 February Plants have a mechanism of protection against temporary deficiency of moisture, but prolonged drought has a negative effect on their development.

In this case not only free water but also colloid-bound water is lost, which leads to decrease of adsorption capacity of colloids, their watering degree, protoplasm viscosity; synthesis of proteins and chlorophyll stops; phosphorus exchange is disturbed; nucleic acids, phosphatides, nucleoproteins decay; transition of mineral phosphorus into organic one reduces; ratio of organic phosphorus to mineral phosphorus decreases.

The main organic matter includes proteins and other nitrogenous compounds amino acids, peptides , fats lipids, oils , carbohydrates starch, sugars, glucose, fructose, cellulose, lignin, fiber, pectin substances.

Mineral salts are represented by inorganic compounds of calcium, phosphorus, potassium, magnesium, sulfur and others. The chemical composition of plants is represented by more than 70 chemical elements, with oxygen, carbon and hydrogen having the largest mass fraction.

Carbon dioxide and water are converted into nitrogen-free organic compounds in plants during photosynthesis. The content of nitrogen and ash elements in plants can vary greatly and depends on the biological characteristics and growing conditions. For example, there are more ash elements in the roots, stems, and leaves than in the seeds.

The composition of ash is also different for different plants, reflecting the varying needs of crops in the elements of mineral nutrition. The content of phosphorus, potassium, calcium and magnesium is usually expressed as their oxides. Necessary elements are those that are involved in the life processes of plants and cannot be replaced by others.

The conditionally necessary elements are those that, according to research data, can have a positive effect on the development of some plants. Macronutrients macroelements — elements which content in plant organism ranges from hundredths to even percent. Micronutrients microelements — elements, the content of which is expressed in thousandths and hundred-thousandths of a percent.

The effectiveness of some trace elements depends on natural and climatic conditions. For example, a positive effect of zinc, manganese and iron is observed on neutral soils of the steppe zone, especially on carbonate black soils, whereas plants often suffer from their excess on sod-podzolic soils.

In the forest-steppe and steppe zones there is rarely an increase in yield from the use of copper microfertilizers, except for corn in some cases. On the contrary, on drained boggy peat soils copper as a microfertilizer is a prerequisite for high yields of grain crops. Molybdenum almost universally has a positive effect on the yield of legume crops, which is associated with its participation in the physiological and biochemical processes of atmospheric nitrogen fixation by nodule bacteria.

However, the effectiveness of molybdenum in different soil and climatic conditions is different, which is explained by the different content of its mobile forms in the soil. Ultra-micronutrients are elements with a content of less than one hundred thousandth of a percent. Ultra-micronutrients include gold, silver, chromium, nickel, tungsten, bromine, uranium, rubidium, cesium, and others.

The physiological significance of these elements in plant life is poorly understood. The division into macro-, micro- and ultra-microelements is conditional. For example, iron, according to its content in plants, belongs to macronutrients, but according to the functions it performs, to micro-nutrients.

The content of trace elements in various plant organs follows certain patterns. Thus, manganese and molybdenum, more often, in large amounts are contained in leaves, while zinc, boron, cobalt, copper with sufficient supply are accumulated in both vegetative and generative organs.

Grain crops are characterized by higher content of boron in grain and legumes — in vegetative organs. Different biological groups of plants differ in their requirements for optimal concentrations of trace elements. For example, corn and tobacco have a greater need for zinc, and grain crops — for manganese and molybdenum.

Plants absorb most of their nutrients in ionic form through the root system. Amino acids, sugars, and sugar-phosphates can be used in small amounts for plant nutrition. Once in the plant, amino acids are deaminated and the ammonia released is used in synthetic processes.

These ions are formed in the soil from organic matter by microbial ammonification and nitrification. The nitrate form is reduced to ammonia by enzymes. The ammonia form of nitrogen is used in the reaction of substitution of the oxygen atom of the carbonyl group of keto acids to form the corresponding amino acid:.

The process of nitrogen fixation of molecular nitrogen under the action of soil microorganisms plays an important role in the nitrogen nutrition of plants. Important functions in this process are performed by the enzymes nitrogenase, light hemoglobin, compounds of vitamin B 12 group, iron, molybdenum, cobalt, copper, etc.

Sulfur is assimilated by plants in the form of sulfate SO 4 In plants, sulfate is reduced to sulfite SO 3 2- and sulfide S 2- , which form sulfhydryl groups S-H or disulfide -S-S- groups by adding hydrogen.

Sulfur is a part of acetylcoenzyme A, the amino acids cysteine, cystine, and methionine. Phosphorus is absorbed by plants in the form of phosphates H 2 PO 4 — , HPO 4 2- or PO 4 In plants, phosphorus is part of nucleic acids, phospholipids — compounds responsible for the properties of cell membranes, coenzymes, including pyridine nucleotides and nucleoside phosphates.

Adenosine phosphates are important in energy metabolism. Primary metabolism of phosphorus involves its involvement in nucleotide synthesis within milliseconds. At exposures of up to 10 minutes, phosphorus is detected as part of nucleic acids.

Exposures over 3 h, when the metabolic pool of phosphorus acceptors is saturated, show phosphorus entering the vacuole in inorganic form. In the absence of air, the accumulation of phosphorus acceptors not used in respiratory metabolism occurs, which explains the intense accumulation of phosphorus in the roots in the absence of oxygen.

Chlorine enters plants in the form of Cl — chloride. In many plants, chlorine can be present in high concentrations without having a negative effect.

First of all, this applies to halophytes, salt-tolerant plants. Calcium, potassium, magnesium, copper, iron, zinc come to plants in the form of cations, manganese — in the form of cations and anions. High concentration of potassium ions up to mM is a characteristic feature of all plant and animal cells.

Only at a certain concentration of potassium ions can protein biosynthesis, photosynthesis, respiration, and synthesis of high-molecular-weight compounds starch, fats, carbohydrates proceed normally in the cell.

For example, Chemical compounds in plants conduct Chemical compounds in plants process of photosynthesis, which is a series of chemical reactions. Each of the elements and chemical compounds present in soil has specific functions, such as to co-create organic structures, catalyse enzymatic reactions, to act as a charged carrier to maintain electrochemical balance, or to regulate osmotic pressure.

Alkaloids are natural substances Chemical compounds in plants react like bases — like alkalis — and they are bitter, probably to make the plant less palatable to herbivores 2 see the previous section. Alkaloid concentrations are often highest in the most vulnerable tissues or the outermost parts of the plant, such as the external layers of the bark, stems, roots, or the seed tegument 3. Figure 2 shows the chemical structure of some common alkaloids and the plants from which they are obtained.
