Nitrate and what synthetic vegetable protein

Cut ......Does this guy on the first floor understand?

Nitrate is also a nitrogen fertilizer, and we know that nitrogen fertilizer is a fertilizer that contains nitrogen, a nutrient element for crops.

Elemental nitrogen plays a very important role in crop growth, it is a component of amino acids in plants, a component of proteins, and a component of chlorophyll that plays a decisive role in photosynthesis in plants. Nitrogen also helps with crop differentiation. The application of nitrogen fertilizer can not only increase the yield of agricultural products, but also improve the quality of agricultural products.

Here's some information:

Crops have the ability to absorb and assimilate inorganic nitrides. Therefore, in addition to a small amount of soluble nitrogen-containing organic matter existing in the soil, such as urea, amino acids, ammonium, etc., the nitrogen absorbed by crops from the soil is mainly ammonium salt and nitrate, both ammonium nitrogen and nitrate nitrogen, which are absorbed into the body, can be directly combined with organic acids of photosynthesis products to form amino acids, and then form other nitrogen-containing organic matter. Nitrate nitrogen can only be absorbed and utilized after it is reduced to ammonium nitrogen in the body.

The ammonia absorbed by plants and the ammonia reduced by nitrate nitrogen can not accumulate too much in the body, otherwise it will poison the plant, and the ammonia poisoning will reduce the respiration of the plant and hinder the protein synthesis. Unreduced nitrate nitrogen can accumulate in plants, such as dry crops such as wheat and tobacco and salt-tolerant plants growing on saline soils, which can accumulate more nitrate, and vegetables can also accumulate a large amount of nitrate in leaves.

Due to the organic acids that combine with ammonia to form amino acids in crops, ** in photosynthesis products, such as pyruvate (ammoniation into alanine), Q-ketoglutarate (amination into glutamic acid). Therefore, the uptake of nitrogen by plants depends to a large extent on the intensity of photosynthesis, which is consistent with the experience of the masses in practice that the fertilization effect is often better and faster on sunny days.

After applying an appropriate amount of nitrogen fertilizer, the effect of nitrogen fertilizer is most easily observed from the change of plant appearance and leaf color due to the synthesis of a large amount of nitrogen-containing organic matter in the body, which makes the plant grow rapidly and the leaf color turns black.

Although ammonium nitrogen and nitrate nitrogen have the same value as plant nitrogen sources, there are still significant differences in the relative uptake of different plants under the condition that the two nitrogen sources can be selected. This difference is affected by the species, varieties and growth period of the plant, the reaction (pH) of the soil solution, the relative content of various ions in the solution, and the concentration of the two nitrogen sources. Among field crops, dry crops such as tobacco and cotton generally respond better to nitrate nitrogen, while rice absorbs more ammonium nitrogen.

Plants can directly absorb urea and certain ammonium salts as nitrogen sources through leaves and roots. However, the assimilation process of urea in the body has not yet been fully understood, and it is generally believed that urea is decomposed into ammonium nitrogen under the action of urase in crops and then utilized.

In general, nitrate ions are still involved in the synthesis of amino acids and proteins.

Protein is made by condensation of amino acids and has nothing to do with NO3-nitrate.

It is an organic chemical reaction and has nothing to do with inorganic substances.

Nitrate is used in plants, mainly using nitrogen in nitrate.

Nitrogen is a very important element in living organisms, which can be used to build biological macromolecules such as "proteins" and "nucleic acids".

At the same time, nitrogen is also a raw material for the construction of various hormones, pheromones, alkaloids and other substances Haruhiro.
