[Chii chinonzi Huperzine A]

Huperzia imhando ye moss inokura kuChina. Iyo ine hukama nekirabhu mosses (iyo mhuri yeLycopodiaceae) uye inozivikanwa kune dzimwe botanists seLycopodium serratum. Iyo yose yakagadzirwa moss yakashandiswa tsika. Mishonga yemazuva ano yemishonga inoshandisa chete alkaloid yakaparadzana inozivikanwa sehuperzine A. Huperzine A is an alkaloid inowanikwa muhuperzia iyo yakashumwa kudzivirira kuparara kweacetylcholine, chinhu chinokosha chinodiwa netsinga dzetsinga kuendesa ruzivo kubva kune sero kuenda kune rimwe sero. Tsvakurudzo yemhuka yakaratidza kuti huperzine A kukwanisa kuchengetedza acetylcholine inogona kuva yakakura kudarika yemamwe mishonga yemishonga. Kurasikirwa nebasa reacetylcholine chinhu chekutanga chekukanganisika kwakawanda kwekushanda kwehuropi, kusanganisira chirwere cheAlzheimer. Huperzine A inogona zvakare kuve nekudzivirira patishu dzehuropi, ichiwedzera kuwedzera kwayo kugona kwayo kwekubatsira kudzikisa zviratidzo zvekumwe kusagadzikana kwehuropi.

[Basa] Inoshandiswa mukurapa kwakasiyana, huperzine A yakawanikwa ichiita secholinesterase inhibitor, rudzi rwemishonga inoshandiswa kudzivirira kuparara kweacetylcholine (kemikari inokosha pakudzidza nekuyeuka).

Haisi kungoshandiswa sekurapa kwechirwere cheAlzheimer, huperzine A inonziwo inowedzera kudzidza nekuyeuka uye kudzivirira kubva mukuderera kwekuziva kwezera.

Mukuwedzera, huperzine A dzimwe nguva inoshandiswa kuwedzera simba, kuwedzera kusvinura, uye kubatsira mukurapa myasthenia gravis (chirwere che autoimmune chinokanganisa tsandanyama).

A polymer imorekuru hombe (macromolecule) inoumbwa nekudzokorora zvikamu zvezvimiro. Aya ma sub-units anowanzo kubatanidzwa necovalent kemikari zvisungo. Kunyangwe izwi rekuti polymer dzimwe nguva richitorwa kureva mapurasitiki, rinonyatso batanidza kirasi hombe yemakomponi anosanganisira ese echisikigo uye ekugadzira zvinhu ane akasiyana siyana ezvivakwa.

Nekuda kweiyo inoshamisa huwandu hwezvivakwa zvepolymeric zvinhu, ivo vanotamba yakakosha uye yakajairika basa muhupenyu hwezuva nezuva. Iri basa rinotangira kubva kuanozivikanwa ekugadzira mapurasitiki uye elastomers kune echisikigo biopolymers senge nucleic acids uye mapuroteni akakosha kuhupenyu.

Natural polymeric zvinhu zvakaita seshellac, amber, makushe, sirika uye rabha rechisikigo zvakashandiswa kwemazana emakore. Mamwe akasiyana emamwe mapolymer echisikigo aripo, senge cellulose, inova ndiyo huru inoumba huni nemapepa. Rondedzero yemapolymers ekugadzira anosanganisira synthetic rabha, Bakelite, neoprene, naironi, PVC, polystyrene, polyethylene, polypropylene, polyacrylonitrile, PVB, silicone, uye zvimwe zvakawanda.

Kazhinji kazhinji, iyo inoramba yakabatana musana wepolymer inoshandiswa kugadzira mapurasitiki inosanganisira kunyanya kabhoni maatomu. Muenzaniso wakapfava ndeye polyethylene ('polythene' muBritish English), iyo inodzokorodza unit inobva pa ethylene monomer. Zvisinei, zvimwe zvimiro zviripo; semuenzaniso, zvinhu zvakaita sesilicon zvinoumba zvinhu zvakajairika senge silicones, mienzaniso iri Silly Putty uye isina mvura yepombi sealant. Oxygen inowanikwawo mu polymer backbones, yakadai seye polyethylene glycol, polysaccharides (mu glycosidic bonds), uye DNA (mu phosphodiester bonds).

Natural vs synthetic rubber

Rabha rechisikigo, rinobva ku latex, rinenge riri poly-cis-isoprene rine zvisaririra zvetsvina. Kunyangwe ichiratidzira zvinhu zvakawanda zvakanakisa, rabha rechisikigo rinowanzove rakaderera kune ekugadzira rubber, kunyanya maererano nekugadzikana kwayo kwekupisa uye kuenderana kwayo nemafuta epetroleum.

Synthetic rubber inogadzirwa nekupolymerization kweakasiyana petroleum-based precursors anonzi monomers. Iyo yakanyanya kupararira yekugadzira rubbers ndeye styrene-butadiene rubbers (SBR) yakabva kune copolymerization ye styrene uye 1,3-butadiene. Mamwe marabha ekugadzira anogadzirwa kubva kune isoprene (2-methyl-1,3-butadiene), chloroprene (2-chloro-1,3-butadiene), uye isobutylene (methylpropene) ine chikamu chidiki cheisoprene yekuyambuka-yakabatana. Aya uye mamwe mamonomers anogona kusanganiswa muzvikamu zvakasiyana kuti zviitwe copolymerized kugadzira zvigadzirwa zvine huwandu hwemuviri, mechaniki, uye makemikari zvimiro.
