Phenylalanine ——Promote the synthesis of lignin, the precursor of anthocyanin synthesis

Phenylalanine has the generality of amino acids, including the reaction with acid and alkali to form internal salt, the reaction of amino group with 2,4-dinitrofluorobenzene (DNFB), nitrous acid, halogenated hydrocarbon, the esterification of carboxyl group, anhydride and amide. Phenylalanine can react with ninhydrin to form blue purplish red substance. The yield of phenylalanine prepared by synthetic method is low, and it is usually extracted from natural products. Degreased soybean was hydrolyzed with hydrochloric acid to remove acidic amino acids, and phenylalanine and tyrosine were adsorbed with activated carbon or decolorizing resin. Then, phenylalanine was dissolved and separated with solvent. It can also be used to convert phenylalanine in the hydrolysate into 2,5-dibromobenzenesulfonate, and then separate it from amino acids such as leucine and arginine by using the difference of solubility. Phenylalanine is a kind of amino acid, which is involved in sugar metabolism. Phenylalanine can promote the synthesis of anthocyanins. Phenylalanine supplementation during fruit coloring can promote anthocyanin synthesis and fruit coloring.

Role of phenylalanine as a plant amino acid supplement

Early germination and high emergence rate: The application of amino acid humic acid can accelerate seed germination and improve seedling emergence rate, especially in early spring and low temperature (generally, it can germinate 1 ~ 3 days earlier and increase seedling emergence rate by 10 ~ 30%).

Fast absorption: Phenylalanine in amino acid fertilizer can be directly absorbed by various organs of plants, passively absorbed or osmotic absorbed under photosynthesis. Obvious effects can be observed in a short time after use. At the same time, it can promote the early maturity of crops and shorten the growth cycle.

Strengthen physiological and biochemical functions: Phenylalanine in amino acids can strengthen its physiological and biochemical functions after being absorbed by crops. Crops have strong stems, thickened leaves, expanded leaf area, accelerated formation and accumulation of dry matter, and crops can mature early. Due to their enhanced vitality, the performance of cold and drought resistance, dry hot wind resistance, disease and insect resistance and lodging resistance is improved, so as to achieve stable and high yield.

Promote plant photosynthesis: Phenylalanine in amino acids can increase the content of plant chlorophyll, promote the absorption and utilization of carbon dioxide by crops, increase power for photosynthesis and make photosynthesis more vigorous.

Function of improving soil: Amino acid fertilizer has no residue in the fertilizer applied in the field, which can improve the physical and chemical properties of the soil, improve the water and fertility retention and air permeability, and play the role of curing, maturing and improving the soil.
