beta-D-Galactose pentaacetate CAS: 4163-60-4
Beta-D-Galactose pentaacetate ndi mankhwala ochokera ku galactose, shuga wa monosaccharide. Amapangidwa mwa kugawa gulu lililonse la hydroxyl la molekyulu ya galactose yokhala ndi magulu asanu a acetyl.
Kapangidwe kameneka nthawi zambiri kamagwiritsidwa ntchito ngati choteteza ku galactose m'njira zosiyanasiyana zamakemikolo ndi njira zopangira. Mtundu wa pentaacetate umathandiza kukhazikika kwa galactose ndikuletsa kusintha kosafunikira kapena kusintha panthawi yamakemikolo.
Kuphatikiza apo, mankhwalawa angagwiritsidwe ntchito ngati choyambira cha kupanga zinthu zina zochokera ku galactose. Magulu a acetyl amatha kuchotsedwa mwachisawawa kuti apeze zinthu zosiyanasiyana zochokera ku galactose zomwe zili ndi magulu enaake ogwira ntchito.

5-Bromo-4-chloro-3-indolyl-beta-D-glucuronide sodium salt CAS:129541-41-9
Mchere wa sodium wa 5-Bromo-4-chloro-3-indolyl-beta-D-glucuronide ndi mankhwala omwe amagwiritsidwa ntchito kwambiri pofufuza ndi kuzindikira matenda a m'ma laboratories. Nthawi zambiri amatchedwa X-Gluc ndipo amagwiritsidwa ntchito kwambiri ngati gawo lothandizira kuzindikira ntchito ya beta-glucuronidase enzyme.
Pamene beta-glucuronidase ilipo, imadula mgwirizano wa glucuronide mu X-Gluc, zomwe zimapangitsa kuti utoto wabuluu wotchedwa 5-bromo-4-chloro-3-indolyl utuluke. Kachitidwe kameneka kamagwiritsidwa ntchito nthawi zambiri kuzindikira momwe enzyme ya beta-glucuronidase imaonekera m'maselo kapena minofu.
Mchere wa sodium wa X-Gluc umathandiza kuti usungunuke m'madzi amadzimadzi, zomwe zimathandiza kuti ugwiritsidwe ntchito poyesa labotale. X-Gluc imagwiritsidwa ntchito kwambiri mu kafukufuku wa biology ya mamolekyulu kuti iphunzire za majini, ntchito yolimbikitsa, komanso kuyesa majini a reporter. Ingagwiritsidwenso ntchito kuzindikira kupezeka kwa zamoyo zomwe zimapanga beta-glucuronidase, monga mabakiteriya ena, mu maphunziro a microbiology.

1,4-Dithioerythritol (DTE) CAS: 6892-68-8
Dithioerythritol (DTE) ndi mankhwala omwe amagwiritsidwa ntchito kwambiri mu kafukufuku wa biochemical ndi molecular biology. Ndi mankhwala ochepetsa omwe amatha kuswa ma disulfide bonds, omwe ndi ofunikira pa kapangidwe ka mapuloteni ndi kukhazikika. DTE ndi yothandiza kwambiri pokonzekera zitsanzo ndi kuyeretsa mapuloteni chifukwa imathandiza kusunga mapuloteni m'njira zawo zochepetsedwa komanso zogwira ntchito. Ingagwiritsidwenso ntchito kuteteza magulu a thiol pamapuloteni ku okosijeni. Kuphatikiza apo, DTE ili ndi mphamvu zotsutsana ndi ma antioxidants ndipo imatha kuchotsa ma free radicals, zomwe zimapangitsa kuti ikhale yothandiza pakuyesera kosiyanasiyana kwa okosijeni.

Hydrogenated Tallowamine CAS: 61788-45-2
Hydrogenated tallowamine ndi mankhwala omwe ali m'gulu la amine. Amachokera ku tallow, yomwe ndi mafuta ochokera ku nyama. Hydrogenated tallowamine imagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana komanso ntchito zake chifukwa cha mphamvu zake zopanga zinthu.
Monga mankhwala ophera tizilombo toyambitsa matenda, hydrogenated tallowamine imatha kuchepetsa mphamvu ya madzi pamwamba, zomwe zimathandiza kuti afalikire mosavuta komanso mofanana. Izi zimapangitsa kuti ikhale chinthu chofunikira kwambiri mu zinthu monga sopo, zofewetsa nsalu, ndi zotsukira, komwe kumathandiza kukulitsa mphamvu zotsukira ndi kutulutsa thovu. Kuphatikiza apo, hydrogenated tallowamine imatha kugwira ntchito ngati chothandizira kusakaniza mafuta ndi madzi, kapena zinthu zina zosasakanikirana. Izi zimapangitsa kuti ikhale yothandiza popanga zodzoladzola, utoto, ndi zinthu zaulimi, komwe kumathandiza kugawa zosakaniza mofanana ndikukweza magwiridwe antchito onse azinthu.
