I-Glyoxylic acid CAS 298-12-4, inefomula ye-molecule ye-C₂H₂O₃ kanye nesisindo se-molecular 74.04. Isixazululo saso esinamanzi siwuketshezi olungenambala obala, oluncibilika kancane ku-ethanol, ether nasebenzene.

I-Glyoxylic acidiyinhlanganisela ebalulekile yezinto eziphilayo, ehlanganisa iqembu le-aldehyde (-CHO) neqembu le-carboxyl (-COOH), elinefomula yesakhiwo ye-HOCCOOH. Inezinhlobonhlobo zezinto ezibonakalayo namakhemikhali, njengokuminyana kwesihlobo (d₂₀₄) kwe-1.384, inkomba ye-refractive (n₂₀D) ye-1.403, indawo yokubilisa engu-111 ° C, indawo yokuncibilika engu -93 ° C, iphoyinti elikhanyayo lika-103.0g3 ° C, ingcindezi engu-103.9 ° C no-3 ° C 25°C. Kubonakala njengamakristalu amhlophe anephunga elibi. Isixazululo saso esinamanzi siwuketshezi olusobala olungenambala noma oluphuzi ngokukhanyayo, olungancibiliki ku-ether, ethanol ne-benzene. Ingakwazi ukumunca umswakama futhi ibe udaka ngesikhathi esifushane ngemva kokuchayeka emoyeni, futhi iyagqwala.

I-Glyoxylic acid CAS 298-12-4inezinhlobo eziningi zokusetshenziswa emikhakheni ehlukene:

Inkambu yezimonyo:I-Glyoxylic acidisetshenziswa njengesithako nesilungisa izimonyo emkhakheni wezimonyo.

Inkambu yezemithi:I-Glyoxylic acid iyimpahla yokwenziwa yokwenziwa yemithi ephakathi kwemithi efana nezidakamizwa ze-antihypertensive atenolol kanye ne-Dp-hydroxyphenylglycine. I-Glyoxylic acid ingasetshenziselwa ukuhlanganiswa kwe-penicillin yomlomo, i-allantoin, i-p-hydroxyphenylglycine, i-p-hydroxyphenylacetic acid, i-mandelic acid, i-acetophenone, i-α-thiophene glycolic acid, i-p-hydroxyphenylacetamide (isifo senhliziyo nemithambo yegazi kanye nezidakamizwa ze-hypertension njenge-atenolol). Ngesikhathi esifanayo, isetshenziselwa ukukhiqiza imikhiqizo yemithi elwa nesilonda efana ne-capsule ne-allantoin.

Ezolimo:Ososayensi benze upulasitiki osuselwe ku-biomass ozothatha indawo yamapulasitiki endabuko. Le pulasitiki entsha yenziwe ngamakhemikhali ashibhile, lapho i-glyoxylic acid ingahlanganisa ama-molecule kashukela ngamaqembu "anamathelayo" ukuze asebenze njengesakhiwo sepulasitiki. Emkhakheni wezolimo, le pulasitiki entsha ingasetshenziswa ezintweni ezihlukahlukene ezifana nokupakisha, izindwangu, imithi kanye nemikhiqizo ye-elekthronikhi.

Ukuvikelwa kwemvelo:Umjikelezo we-glyoxylate ubaluleke kakhulu emkhakheni we-biochemistry. Ikakhulukazi endaweni engenakho ukukhanya, izitshalo zingakwazi ukuguqula ama-acids anamafutha abe ushukela ngomjikelezo we-glyoxylate ukuze kugcinwe amandla kanye nomthombo wekhabhoni odingekayo ukuze kukhule, kukhuthaze umjikelezo wezinto eziphilayo, futhi kuthuthukise ikhono lokuzivumelanisa nezimo ezimbi njengesomiso nosawoti omningi.

I-unilongkuyintouchwepheshe we-Glyoxylic acid CAS 298-12-4 umkhiqizi, singahlinzeka ngezinhlobonhlobo zokucaciswa komkhiqizo weI-Organic Chemistry, ukuqinisekiswa kwekhwalithi, ukulethwa okusheshayo, kunesitoko. Ngicela, uma uyidingaXhumana nathi.
