I te raumati, ka pāngia ngā tipu e ngā pēhanga maha pērā i te pāmahana teitei, te mārama kaha, te tauraki (te ahotea wai), me te ahotea waikura. Ko te Betaine, hei kaiwhakahaere osmotic nui me te matū wairewa tiaki hototahi, he mahi nui tana ki te ātete o ngā tipu ki ēnei ahotea raumati. Ko ōna mahi matua ko:

1. Te whakahaere i te uruhanga:
Kia mau tonu te pēhanga turgor pūtau:

Ka ngaro te wai i ngā tipu nā te pāmahana teitei me te tauraki, ka piki ake te kaha o te osmotic cytoplasmic (ka nui haere te matotoru), ka ngāwari te matewai me te memenge o ngā pūtau mai i ngā vacuoles e karapoti ana, i ngā pakitara pūtau rānei he kaha ake te mimiti wai. Ka nui te kohi o te Betaine i roto i te cytoplasm, ka whakaiti i te kaha osmotic o te cytoplasm, ka āwhina i ngā pūtau ki te pupuri i te pēhanga turgor teitei, kia ātete ai ki te matewai me te pupuri i te pumau o te hanganga me te mahi a te pūtau.

Te pēhanga osmotic taurite o te vacuolar:

He nui ngā katote kore-waro (pērā i te K⁺, te Cl⁻, me ētahi atu) e kohia ana i roto i te vacuole hei pupuri i te pēhanga osmotic. Ko te nuinga o te wā kei roto te Betaine i te cytoplasm, ā, ko tōna kohi ka āwhina i te taurite i te rerekētanga pēhanga osmotic i waenga i te cytoplasm me ngā vacuole, ka ārai i te kino o te cytoplasm nā te nui o te maroke.

2. Te tiaki i ngā ngota koiora:
Hanganga pūmua pumau:

Ka ngāwari te whakapōrearea me te whakakore i te mahi a te pūmua i ngā pāmahana tiketike. He utu pai, he utu kino hoki (zwitterionic) ngā ngota Betaine, ā, ka taea e rātou te whakaū i te āhua tūturu o ngā pūmua mā te here hauwai me te whakamakuku, ka ārai i te takai hē, te whakakotahitanga, te whakapōrearea rānei i ngā pāmahana tiketike. He mea nui tēnei mō te pupuri i te mahi a ngā whākōkī, ngā pūmua matua i roto i te photosynthesis, me ngā mahi a ētahi atu pūmua metabolic.

Pūnaha kiriata tiaki:

Ka taea e te pāmahana tiketike me ngā momo hāora tauhohe te kino i te hanganga paparanga lipid o ngā kiriuhi pūtau (pērā i ngā kiriuhi thylakoid me ngā kiriuhi plasma), ka arahi ki te rere rerekē o te kiriuhi, te turuturu, tae noa ki te pakaru. Ka taea e te Betaine te whakau i te hanganga kiriuhi, te pupuri i tōna rere noa me tōna urunga whiriwhiri, me te tiaki i te pumau o ngā whekau me ngā whekau whakaahua.

3. Te tiaki i ngā mate pāwera:
Kia mau tonu te taurite osmotic me te whakaiti i ngā kino tuarua i puta mai i te ahotea.

Whakapūmau i te hanganga me te mahi a ngā whākōkī ārai-mate (pēnei i te superoxide dismutase, catalase, ascorbate peroxidase, me ētahi atu), whakarei ake i te whai huatanga o te pūnaha ārai ārai-mate a te tipu, ā, āwhina ā-korekore ki te whakakore i ngā momo hāora tauhohe.
Te tango ā-korekore i ngā momo hāora tauhohe:

Ka taea e te hihi kaha o te rā me te pāmahana teitei i te raumati te whakaputa i te nui o ngā momo hāora tauhohe i roto i ngā tipu, ka puta ai te kino o te waikura. Ahakoa ehara te betaine i te antioxidant kaha, ka taea te whakatutuki mā te:

4. Te tiaki i te whakaahua-whakawhitiwhiti:
Ka nui te kino o te pūnaha whakaahua II i te pāmahana teitei me te ahotea mārama kaha. Ka taea e te Betaine te tiaki i te kiriuhi thylakoid, te pupuri i te pumau o te matatini pūnaha whakaahua II, te whakarite i te whakahaere maeneene o te mekameka kawe irahiko, me te whakaiti i te aukati whakaahua o te whakaahua.

5. Hei kaituku methyl:

Ko te Betaine tētahi o ngā kaituku methyl nui i roto i ngā rauropi ora, e whai wāhi ana ki te huringa methionine. I raro i ngā āhuatanga ahotea, ka whai wāhi pea ia ki te hanga, ki te whakahaere rānei i te pākia o ētahi matū e aro ana ki te ahotea mā te whakarato i ngā rōpū methyl.

Hei whakarāpopototanga, i te raumati werawera, ko te mahi matua a te betaine ki ngā tipu ko:

Te pupuri wai me te ātete ki te tauraki:te whawhai ki te matewai mā te whakahaere i te osmosis.
Te ātete ki te wera:ka tiaki i ngā pūmua, ngā whākōkī, me ngā kiriuhi pūtau mai i te kino o te pāmahana tiketike.

Ātete ki te waikura:ka whakanui ake i te kaha antioxidant me te whakaiti i te kino photooxidative.
Kia mau tonu te whakapūngao whakaahua:te tiaki i ngā okana whakaahua me te pupuri i te pūtake o te pūngao.

Nō reira, ina kite ngā tipu i ngā tohu ahotea pēnei i te pāmahana teitei me te tauraki, ka whakahohehia e rātou te ara hanga betaine (mā te waikura rua-taahiraa o te choline i roto i ngā chloroplasts te nuinga), ka kohikohi kaha i te betaine hei whakarei ake i tō rātou ātete ki te ahotea me te whakapai ake i tō rātou kaha ki te ora i roto i ngā taiao raumati uaua. Ko ētahi hua e ātete ana ki te tauraki me te tote (pēnei i te pīti huka, te pīnihi, te witi, te parei, me ētahi atu) he kaha ki te kohikohi betaine.

I roto i te mahi ahuwhenua, ka whakamahia hoki te rehu betaine mai i waho hei whakaohooho koiora hei whakarei ake i te ātete o ngā hua (pērā i te kānga, te tōmato, te tiri, me ētahi atu) ki te pāmahana tiketike o te raumati me te ahotea tauraki.
