Lehlabuleng, limela li tobana le likhatello tse ngata tse kang mocheso o phahameng, khanya e matla, komello (khatello ea metsi), le khatello ea oxidative. Betaine, joalo ka selaoli sa bohlokoa sa osmotic le solute e ts'ireletsang, e bapala karolo ea bohlokoa ho hanetseng ha limela likhatellong tsena tsa lehlabula. Mesebetsi ea eona ea mantlha e kenyelletsa:

1. Permeation regulation:
Boloka khatello ea cell turgor:

Mocheso o phahameng le komello li etsa hore limela li lahleheloe ke metsi, e leng se lebisang ho eketseha ha bokhoni ba cytoplasmic osmotic (ho ba denser), e leng ho bakang habonolo ho felloa ke metsi le ho senyeha ha lisele tse tsoang ho li-vacuoles tse potolohileng kapa marako a lisele tse nang le matla a matla a ho monya metsi. Betaine e bokellana ka bongata ho cytoplasm, ka katleho ho fokotsa bokhoni ba osmotic ea cytoplasm, ho thusa lisele ho boloka khatello e phahameng ea turgor, kahoo e hanela ho felloa ke metsi 'meleng le ho boloka botšepehi ba sebopeho sa lisele le mosebetsi.

Khatello e leka-lekaneng ea vacuolar osmotic:

Li-ion tse ngata tsa inorganic (tse kang K ⁺, Cl ⁻, joalo-joalo) li bokella ka har'a vacuole ho boloka khatello ea osmotic. Betaine e teng haholo-holo ho cytoplasm, 'me ho bokella ha eona ho thusa ho leka-lekanya phapang ea khatello ea osmotic pakeng tsa cytoplasm le vacuoles, ho thibela tšenyo ea cytoplasm ka lebaka la ho felloa ke metsi ho feteletseng.

2. Ho sireletsa li-biomolecules:
Sebopeho se tsitsitseng sa protheine:

Lithempereichara tse phahameng li ka baka protheine denaturation le ho se sebetse habonolo. Limolek'hule tsa betaine li na le litefiso tse ntle le tse mpe (zwitterionic) 'me li ka tsitsisa sebopeho sa tlhaho sa liprotheine ka hydrogen bonding le hydration, ho thibela ho fosahala, ho kopanya, kapa denaturation ho mocheso o phahameng. Sena se bohlokoa bakeng sa ho boloka tšebetso ea enzyme, liprotheine tsa bohlokoa ho photosynthesis, le mesebetsi ea liprotheine tse ling tsa metabolism.

Sistimi ea ts'ireletso ea lifilimi:

Mocheso o phahameng le mefuta ea oksijene e sebetsang e ka senya sebopeho sa lipid bilayer ea lisele tsa lisele (tse kang li-membrane tsa thylakoid le li-membrane tsa plasma), tse lebisang ho metsi a sa tloaelehang a membrane, ho lutla, esita le ho qhalana. Betaine e ka tsitsisa sebopeho sa lera, ho boloka metsi a eona a tloaelehileng le ho kenella ka mokhoa o ikhethileng, le ho sireletsa botšepehi ba litho tsa photosynthetic le li-organelles.

3. Tšireletso ea Antioxidant:
Boloka botsitso ba osmotic le ho fokotsa tšenyo ea bobeli e bakoang ke khatello ea maikutlo.

Tsitsisa sebopeho le ts'ebetso ea li-enzyme tsa antioxidant (joalo ka superoxide dismutase, catalase, ascorbate peroxidase, joalo-joalo), ntlafatsa ts'ebetso ea sistimi ea ts'ireletso ea antioxidant ea semela, 'me ka tsela e sa tobang thusa ho hlakola mefuta ea oksijene e sebetsang.
Ho tlosoa ka tsela e sa tobang ha mefuta ea oksijene e sebetsang:

Khanya e matla ea letsatsi le mocheso o phahameng hlabula li ka susumetsa tlhahiso ea mefuta e mengata ea oksijene e sebetsang limeleng, e bakang tšenyo ea oxidative. Le hoja betaine ka boeona e se antioxidant e matla, e ka finyelloa ka:

4. Ho sireletsa photosynthesis:
Mocheso o phahameng le khatello e matla ea leseli li baka tšenyo e kholo ho mochine oa mantlha oa photosynthesis, photosystem II. Betaine e ka sireletsa lera la thylakoid, ho boloka botsitso ba photosystem II e rarahaneng, ho netefatsa ts'ebetso e ntle ea ketane ea lipalangoang tsa elektronike, le ho fokotsa photoinhibition ea photosynthesis.

5. Joaloka mofani oa methyl:

Betaine ke e 'ngoe ea bafani ba bohlokoa ba methyl linthong tse phelang, tse amehang potolohong ea methionine. Tlas'a maemo a khatello ea maikutlo, e ka nka karolo taolong ea ho kopanya kapa ea metabolic ea lintho tse ling tse arabelang khatello ea maikutlo ka ho fana ka lihlopha tsa methyl.

Ka kakaretso, nakong ea lehlabula le chesang, mosebetsi oa mantlha oa betaine limela ke:

Ho boloka metsi le komello:ho loantša ho felloa ke metsi 'meleng ka taolo ea osmotic.
Tšireletso ea ho hanyetsa mocheso:e sireletsa liprotheine, li-enzyme le li-membrane tsa lisele ho senya mocheso o phahameng.

Ho hanyetsa oxidation:e eketsa matla a antioxidant le ho fokotsa tšenyo ea photooxidative.
Boloka photosynthesis:sireletsa litho tsa photosynthetic le ho boloka matla a motheo.

Ka hona, ha limela li bona matšoao a khatello ea maikutlo joalo ka mocheso o phahameng le komello, li kenya tšebetsong tsela ea betaine synthesis (haholo-holo ka oxidation ea mehato e 'meli ea choline ho chloroplasts), e bokella betaine ka mafolofolo ho matlafatsa ho hanyetsa khatello ea maikutlo le ho ntlafatsa bokhoni ba bona ba ho phela maemong a thata a lehlabula. Lijalo tse ling tse mamellang komello le letsoai (tse kang li-sugar beet ka botsona, spinach, koro, harese, joalo-joalo) li na le bokhoni bo matla ba ho bokella betaine.

Tlhahisong ea temo, ho fafatsa ka ntle ho betaine ho boetse ho sebelisoa e le biostimulant ho matlafatsa khanyetso ea lijalo (tse kang poone, tamati, chili, joalo-joalo) ho mocheso o phahameng oa lehlabula le khatello ea komello.
