2. Glyceryl butyrate

He kakara kino te waikawa pūturiki, ā, he ngāwari ki te whakapūpū, ā, he uaua ki te tae atu ki te pito o muri o te whekau i muri i te kainga e ngā kararehe, nō reira kāore e taea te whakamahi tika i roto i te hanga. Ko te Glyceryl butyrate te hua ngako o te waikawa pūturiki me te glycerin. Ka herea te waikawa pūturiki me te glycerin e ngā hononga covalent. He pumau mai i te pH1-7 ki te 230 ℃. I muri i te kainga e ngā kararehe, kāore te glyceryl butyrate e pirau i roto i te puku, engari ka pirau ki te waikawa pūturiki me te glycerin i roto i te whekau i raro i te mahi a te lipase pancreatic, ka tukuna mārire te waikawa pūturiki. Ko te Glyceryl butyrate, hei tāpiringa kai, he watea ki te whakamahi, he haumaru, kāore he paitini, ā, he reka motuhake. Ehara i te mea ka whakaoti noa i te raruraru he uaua ki te tāpiri i te waikawa pūturiki hei wai me te kakara kino, engari ka whakapai ake i te raruraru he uaua ki te tae atu te waikawa pūturiki ki te ara whekau ina whakamahia tika. E kiia ana ko tētahi o ngā hua pai rawa atu o te waikawa pūturiki me te anti histamine.

2.1 Te Glyceryl Tributyrate me te Glyceryl Monobutyrate

TributyrinKei roto i tēnei ko ngā ngota e 3 o te waikawa butyric me te ngota kotahi o te glycerol. Ka tukuna mārire e Tributyrin te waikawa butyric ki roto i te whekau mā te pancreatic lipase, ka tukuna tetahi wāhanga ki mua o te whekau, ā, ka taea e tetahi wāhanga te tae ki muri o te whekau hei mahi; Ka hangaia te glyceride waikawa monobutyric e te kotahi ngota o te waikawa butyric e herea ana ki te wāhi tuatahi o te glycerol (wāhi Sn-1), he āhuatanga hydrophilic me te lipophilic. Ka taea e ia te tae ki te pito muri o te whekau me te wai nakunaku. Ka tukuna ētahi waikawa butyric e te pancreatic lipase, ā, ka mimiti tika ētahi e ngā pūtau epithelial whekau. Ka pakaruhia hei waikawa butyric me te glycerol i roto i ngā pūtau mucosal whekau, ka whakatairanga i te tipu o ngā villi whekau. He polarity me te nonpolarity ngota o te Glyceryl butyrate, ka taea te uru pai ki te kiriuhi pūtau hydrophilic, lipophilic rānei o ngā huakita pathogenic matua, ka whakaekea ngā pūtau huakita, ka whakangaro i te hanganga pūtau, ka patu i ngā huakita kino. He kaha te pānga patu huakita o te waikawa monobutyric glyceride ki ngā huakita karamu-pai me ngā huakita karamu-kino, ā, he pai ake te pānga patu huakita.

2.2 Te whakamahinga o te glyceryl butyrate i roto i ngā hua wai

Ko te Glyceryl butyrate, he mea hanga mai i te waikawa butyric, ka taea te tuku i te waikawa butyric i raro i te mahi a te lipase pancreatic puku, ā, kāore he kakara, he pumau, he haumaru, ā, kāore he toenga. Ko tētahi o ngā mea pai hei whakakapi i ngā paturopi, ā, e whakamahia whānuitia ana i roto i te mahi ahuwhenua ika. I whakaatu a Zhai Qiuling me ētahi atu, i te wā i tāpirihia ai te 100-150 mg/kg tributylglycerol ester ki te kai, ka taea te whakanui ake i te tere o te taumaha, te tere tipu motuhake, ngā mahi a ngā momo whākōkī nakunaku me te teitei o ngā villi puku i mua me muri i te tāpiritanga o te 100 mg/kg tributylglycerol ester; i kitea e Tang Qifeng me ētahi atu kairangahau ko te tāpiri i te 1.5g/kg tributylglycerol ester ki te kai ka taea te whakapai ake i te mahi tipu o Penaeus vannamei, me te whakaiti nui i te maha o ngā vibrio pathogenic i roto i te puku; Jiang Yingying me ētahi atu. i kitea ko te tāpiri i te 1g/kg o te tributyl glyceride ki te whāngai ka taea te whakanui ake i te tere pikinga taumaha o te Allogynogenetic crucian carp, te whakaiti i te tauwehenga whāngai, me te whakanui ake i te mahi a te superoxide dismutase (SOD) i roto i te hepatopancreas; i whakaatuhia e ētahi rangahau ko te tāpiri i te 1000 mg/kgtributyl glycerideki te kai ka nui ake te kaha o te intestinal superoxide dismutase (SOD) o te ika kāpa Jian.
