HANGANGA:
Whakaahuatanga:
Ko te Methionine he waikawa α-amino me te tātai matū HO2CCH(NH2)CH2CH2SCH3. Kua whakarōpūtia tēnei waikawa amino nui hei waikawa kore-polar. Ka whakakōwaetia tēnei waikawa amino e te kōwae tīmatanga AUG e tohu ana i te rohe whakakōwae o te mRNA te wāhi ka tīmata te whakamāoritanga ki te pūmua.

Whakamahinga
Te whakaputanga o ngā pūhui pūngāwerewere e pā ana ki te reka o ngā kai mai i te whakangaromanga o te DL-methionine e Strecker.
Tērā pea ka whakapai ake i te uara pūmua mā te tāpiri i te methionine ki ēnei kai i roto i ngā rahinga e tika ana. He pai ake te whakamahi i te DL-methionine i roto i te ōhanga.
He waikawa amino kore-polar nui me ngā āhuatanga tiaki ahotea waikura
I ētahi wā ka hoatu te DL-Methionine hei tāpiringa ki ngā kurī; ka āwhina i te ārai i ngā kurī kei kino i te tarutaru mā te whakaiti i te pH o te mimi.
E whakaaetia ana te methionine hei tāpiringa ki te whāngai manu rauropi i raro i te kaupapa rauropi kua whakamanahia e te US.
Te Tākai me te Tukunga
25KG/Pahu.
Nō ngā taonga noa, ā, ka taea te tuku mā te moana me te rangi
Te pupuri me te rokiroki
Te roa o te oranga: 24 marama mai i te rā i hangaia ai, i roto i te takai taketake kāore anō kia whakatuwheratia, rongoatia ki te wāhi matao, maroke, ā, kāore e taea te ārai i te rā tika, i te wai rānei.
Whare putunga hauhautanga, Whakamaroke pāmahana iti, Wehea mai i ngā waikura me ngā waikawa.
