I-Glyoxylic acid CAS 298-12-4, inefomula yama-molecule engu-C₂H₂O₃ kanye nesisindo sama-molecule esingu-74.04. Isixazululo sayo samanzi siwuketshezi olucacile olungenambala, oluncibilika kancane ku-ethanol, i-ether kanye ne-benzene.

I-Glyoxylic acidiyinhlanganisela ebalulekile yezinto eziphilayo, equkethe iqembu le-aldehyde (-CHO) kanye neqembu le-carboxyl (-COOH), enefomula yesakhiwo se-HOCCOOH. Inezakhiwo ezahlukahlukene zomzimba nezamakhemikhali, njengobuningi obuhlobene (d₂₀₄) obungu-1.384, inkomba yokubuyisa (n₂₀D) obungu-1.403, iphuzu lokubila elingu-111°C, iphuzu lokuncibilika elingu--93°C, iphuzu lokushelela elingu-103.9°C, kanye nomfutho womusi ongu-0.0331mmHg ku-25°C. Ibonakala njengamakristalu amhlophe anephunga elibi. Isixazululo sayo samanzi siwuketshezi olukhanyayo olungenambala noma oluphuzi olukhanyayo, olungancibiliki ku-ether, i-ethanol kanye ne-benzene. Ingamunca umswakama futhi ibe yi-slurry ngesikhathi esifushane ngemva kokuvezwa emoyeni, futhi iyabola.

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

Insimu yezimonyo:I-Glyoxylic acidisetshenziswa njengomenzi wamakha kanye nokulungisa izimonyo emkhakheni wezimonyo.

Insimu yezemithi:I-Glyoxylic acid iyinto eluhlaza yokwenziwa yemithi ephakathi efana nemithi yokulwa nomfutho wegazi ophezulu i-atenolol kanye ne-Dp-hydroxyphenylglycine. I-Glyoxylic acid ingasetshenziswa ukuhlanganisa i-penicillin yomlomo, i-allantoin, i-p-hydroxyphenylglycine, i-p-hydroxyphenylacetic acid, i-mandelic acid, i-acetophenone, i-α-thiophene glycolic acid, i-p-hydroxyphenylacetamide (izifo zenhliziyo kanye nemithi yomfutho wegazi ophezulu njenge-atenolol). Ngesikhathi esifanayo, isetshenziselwa ukukhiqiza imikhiqizo yemithi yokulwa nesilonda njenge-capsule kanye ne-allantoin.

Ezolimo:Ososayensi bathuthukise ipulasitiki etholakala kwi-biomass ukuze ithathe indawo yepulasitiki yendabuko. Le pulasitiki entsha yenziwe ngamakhemikhali ashibhile, lapho i-glyoxylic acid ingahlanganisa khona ama-molecule kashukela namaqembu “anamathelayo” ukuze asebenze njengesisekelo sepulasitiki. Emkhakheni wezolimo, le pulasitiki entsha ingasetshenziswa ezinhlotsheni ezahlukene ezifana nokupakisha, izindwangu, imithi, kanye nemikhiqizo kagesi.

Ukuvikelwa kwemvelo:Umjikelezo we-glyoxylate ubaluleke kakhulu emkhakheni we-biochemistry. Ikakhulukazi endaweni engenakukhanya, izitshalo zingaguqula ama-fatty acid abe ushukela ngomjikelezo we-glyoxylate ukuze zilondoloze amandla kanye nomthombo wekhabhoni odingekayo ekukhuleni, zikhuthaze umjikelezo wezinto eziphilayo, futhi zithuthukise ikhono lokuzivumelanisa nezimo ezimbi njengesomiso kanye nosawoti omningi.

I-Unilongkuyintoi-Glyoxylic acid yobungcweti i-CAS 298-12-4 umkhiqizi, singanikeza imininingwane ehlukahlukene yomkhiqizo weI-Chemistry Yezinto Eziphilayo, isiqinisekiso sekhwalithi, ukulethwa okusheshayo, ube naso esitokweni. Uma usidinga, sicelaXhumana nathi.
