Ho boloka metsi a hydrophilic: asiti ea polyglutamic e khona ho monya ka makhetlo a 1500 a limolek'hule tsa metsi, ho boloka metsi le limatlafatsi kabong e sebetsang ea mobu, ho khothaletsa ho monya lijalo, ho fokotsa mouoane oa metsi le ho lutla, 'me e ka thibela ho bola ka potlako le tahlehelo ea likarolo tsa metsi le manyolo, fokotsa ka ho toba palo ea manyolo le metsi a sebelisoang ho feta 20%.

Ho boloka manyolo le ho eketseha ka katleho: Ketane e telele ea PGA e na le palo e kholo ea lihlopha tsa mahala tsa carboxyl tsa motlakase, tse nang le bokhoni bo matla ba ho bapatsa bakeng sa li-ion tsa limatlafatsi tse ntle.Bophahamo ba eona le ho fapanyetsana ha eona ke makhetlo a ka bang 100 a mobu oa tlhaho, o fokotsang ho tsoa ha limatlafatsi le ho teteka, o nontša limatlafatsi tse mahareng le tse nyane joalo ka N, P, K, Ca le Mg, le ho ntlafatsa matla a phepelo ea limatlafatsi mobung.

Ntlafatso ea mobu: ntlafatsa ho boloka metsi, ho kenella ha metsi le ho kenella ha moea mobung.Ka nako e ts'oanang, polyglutamic acid e na le palo e kholo ea lihlopha tsa carboxyl le lihlopha tsa amino, tse ka thibelang phetoho ea acid-base e bakoang ke li-ion tsa hydrogen le hydroxide ion, ho leka-lekanya boleng ba acid-base ea mobu, le ho qoba boleng ba mobu oa asiti le mobu. popeho ya poleiti e bakoang ke tshebediso ya nako e telele ya menontsha ya dikhemikhale.

Ntlafatsa mamello ea khatello ea maikutlo: polyglutamate e ka susumetsa kholo ea moriri oa motso oa semela le kholo ea metso, kahoo e ntlafatsa bokhoni ba motso ho monya limatlafatsi.Tikolohong ea komello le likhohola le mocheso o tlase, e ka netefatsa ka nepo ho monya ho tloaelehileng ha metsi le limatlafatsi.
