DMPT, CAS NO.: 4337-33-1.Zvakanakisamvura inokwezvaikozvino!

DMPTinozivikanwa se dimethyl-β-propiothetin, inowanikwa zvakanyanya mumakwenzi egungwa uye halophytic yakakwirira miti.DMPT ine simba rekusimudzira pane chikafu chemetabolism yemhuka dzinoyamwisa, huku, uye mhuka dzemumvura (hove uye shrimp).DMPT chinhu chine simba rakasimba rekukwezva pamhuka dzemumvura pakati pemakomboni ese anozivikanwa ane (CH) uye S-mapoka.

1. Kunobva DMPT

Iyo dimethyl sulfide (DMS) inogadzirwa nePolysipho - nia fastigata inonyanya kubvaDMPT, iyo inoshandawo methyl donor mualgae, uye iyo huru osmotic regulator yealgae uye mudflat chirimwa Spartina angelica zvakare DMPT.Zviri mukati meDMPT zvinosiyana pakati pemhando dzakasiyana dzegungwa regungwa, uye zvirimo zvemhando imwechete yegungwa zvinosiyanawo mumwaka wakasiyana.DMPT inogona kukurumidzira zvakanyanya kudya uye kukura kwehove dzakasiyana siyana dzemvura yakachena.Kudyisa inducing mhedzisiro yeDMPT yakasiyana nezvimwe zvinhu zvakaita seL-amino acids kana nucleotides, uye ine kudya uye kukura kwekusimudzira mhedzisiro pane dzinenge dzese mhuka dzemumvura.

2.1 Inoshanda Ligands seRavira Receptors

Tsvagiridzo yezvinogamuchirwa muhove kemikari inonzwa nhengo dzinogona kudyidzana ne (CH) S-mapoka achiri asina chinhu.Kubva pane iripo maitiro ekuedza mhedzisiro, zvinogona kuongororwa kuti hove zvechokwadi dzine kuravira zvinogamuchira zvinogona kudyidzana neakaderera mamorekuru huremu makomisheni ane (CH), N -, uye (CH2) 2S - mapoka.

2.2 Semupiro wemethyl

Iyo (CH) uye S-mapoka paDMPTmamorekuru ndiwo masosi emapoka emethyl anodiwa pakudya kwemhuka metabolism.Kune marudzi maviri emethyltransferases (EC2.1.1.3 uye EC2.1.1.5) muchiropa chemhuka chinoshandiswa nemhuka (CH) uye S.

Zvakaonekwa kuti kuwanda kweDMPT uye chiyero chekubuda kweDMS mumasero emugungwa akawedzera nekuwedzera kwemunyu mune tsika yepakati peiyo tsika yegungwa (Hymenonas carterae).

DMPTinopfumiswa mumasero ezvizhinji zve phytoplankton, algae, uye symbiotic mollusk dzakadai seclams nemakorari, pamwe chete nekrill nehove miviri.Iida et al.(1986) yakasimbisa kuti zvirimo muDMPT uye kugadzirwa kweDMS muhove zvakabatana neDMPT yemukati mukudya kwavo, zvichiratidza kuti mupunga weDMPT mumhuka unobva kuchirauro uye unopinda mumuviri wemhuka yemunhu kuburikidza neketani yekudya mumakungwa ecosystems. .Algae inogona kugadzira DMPT uye kuiunganidza pamazinga akakwirira (3-5 mmol / L) mumuviri.Iyo DMPT muhove uye mollusks iri padyo nemazinga avo mukudya, uye kuwanda kweDMPT kunoratidza kuderera kwemaitiro ealgae (1 mmol/L), mollusks (0.1 mmol/L), uye hove (0.01 mmol/ L).

Iyo Physiological Mechanism yeDMPTChiito

Mumakore achangopfuura, tsvakurudzo yakawana kuti DMPT ine simba rekusimudzira pakudya uye kukura kwehove dzakasiyana-siyana dzemugungwa nemvura yakachena, crustaceans, uye shellfish, iyo inogona kuvandudza maitiro avo ekudzivisa kushushikana uye maitiro ekurovedza muviri, uye kuwedzera ma enzymes eboka rezasi reboka remethyl. mukudya.Kushandisa chiropa chegungwa bream sechinhu chekuedza uye mishonga yakasiyana-siyana ine (CH) uye S - mapoka se substrates, zvakaonekwa kuti E C.2.1.1.3 uye E Basa re enzyme rakakwirira apo DMPT inoshandiswa se substrate.

3. Zvokudya zvinovaka muviri zveDMPT pamhuka dzemvura

Makumi maviri akaderera molecular uremu organic komisheni ine (CH) uye S-mapoka akashandiswa kuruma maitiro uye electrophysiological kuedza pamvura yegungwa nehove dzemvura yakachena.Zvakaonekwa kuti DMPT yakanga ine simba guru rekusimudzira maitiro ekurumwa kwemhando nhatu dzehove, kusanganisira mvura yakachena tuna, carp, uye black crucian carp (Carassius auratus cuviera).Yakasimudzirawo zvakanyanya maitiro ekudya emvura yegungwa chiyero chechokwadi (Pagrus chikuru) uye zviyero zvishanu (Seriola quinquera diata).

Sanganisa DMPT nemamwe makomisheni ane sarufa pahuwandu hwe1.0mmol/L.mukudya kwakasiyana-siyana kwekuedza, uye kutsiva boka rekutonga nemvura yakasvibiswa kuti iite bvunzo dzemhinduro dzekudya pacrucian carp.Zvigumisiro zvakaratidza kuti mumapoka mana ekutanga ekuedza, boka reDMPT raiva nevhareji ye126 yakakwirira yekurumwa frequencies kupfuura boka rekutonga;Muchikamu chechipiri che5-boka rekuedza, boka reDMPT raiva 262.6 nguva dzakakwirira kudarika boka rekutonga.Mukuenzanisa kuyedza ne glutamine, zvakaonekwa kuti pakusangana kwe1.0mmol/L.
