Brief:
γ-ploy glutamic acid (γ-PGA) is a kind of water soluble, biodegradable ,non-toxic ,fermentative biopolymer materials. γ-PGA is a kind of anion natural polymer , it is homo-polyamide linked by amido bond between α-NH2 and γ-COOH . the molecular weight scope is from 5 to 2 million Dalton.
Functional characters of different ingredients in polyglutamic acid:
1.Macro molecular polymer, water holding ，fertilizer preservation，improve the soil structure.chelating macro middle micro elements to improve the utility of fertilizer, soil pH buffer.
2.Poly-peptide , plant growth promotor，increase photosynthetic efficiency, improve crop stress-resist ability.mix with foliar spray fertilizer or pesticide， prolong the stay times on leaves to improve the utility.
3.Monomer glutamic acid ,glutamic acid can be absorbed by plants or microbes in soil ,increase the yield and the quality of fruits.
Only macro molecular polyglutamic acid（2million-3million Dalton） with the ability to improve the utility of chemical fertilizers or increase the structure of soil :
● The amino and carboxyl groups ratio is 1:2 in PGA ，there are one 10-20thousands of free carboxyl groups in PGA，its negatively charged and will chelate cationic K Ca Mg and so on , to prevent locked and improve the utility of them .
● The hydrophilic property of carboxyl group is stronger than amino groups ，so the water holding capacity of PGA is more stronger than the same molecular hyaluronic acid.
● The macro molecular polyglutamic acid is network structure and slow release nutrients to against loss.
● The macro molecular polyglutamic acid can hold moisture around plant root to prevent fertilizers loss and improve the utility .
Useage：
