Ifu ya Proline
Proline (mu magambo ahinnye nka Pro cyangwa P), hamwe na formula ya shimi C5H9NO2 n'uburemere bwa molekile 115.13, ni aside amino ikora mu buryo bw'ikirere. α- Aside amino, zitagira aho zibogamiye, zifite ingingo ya isoelectric ya 6.30, zifite ubushobozi bwo gushonga mu mazi kurusha izindi aside amino iyo ari yo yose, kandi zishobora gushonga hafi 162g muri garama 100 z'amazi kuri 25 ℃. Byoroshye gushonga ariko ntibyoroshye gushonga, bifite uburyohe bwiza. Gushyushya hamwe na ninhydrine bitanga imvange y'umuhondo. Iyo imaze kwinjira mu muyoboro wa peptide, hydroxylation ishobora kubaho, bigatuma habaho 4-hydroxyproline, ikaba ari igice cy'ingenzi cya kolajeni y'inyamaswa. Hydroxyproline iboneka kandi muri poroteyine zitandukanye z'ibimera, cyane cyane zijyanye no gushinga inkuta z'uturemangingo. Ibimera bikunze kugira ubwiyongere bunini bwa proline mu bihe bitandukanye bibi nko kubura amapfa, ubushyuhe bwinshi, ubushyuhe buke, n'umunyu. Ikoreshwa cyane mu buvuzi, mu bintu by'ibinyabuzima, mu nganda, no mu bindi.
Hari ubwoko butatu bwa proline:Proline ya DL, L-proline, na D-proline. Proline izwi cyane ni L-proline, aside amine isanzwe. Ku bushyuhe bw'icyumba, iki gicuruzwa kiba ari kristu ikoze mu cyuma. Kirabora vuba iyo gishyushye kugeza kuri 215-220 ℃. Gishonga mu mazi ashyushye na ethanol. Kiryoshye gato kandi gikozwe mu buryo bwa hygroscopic. Gutandukanya mu gisubizo cya alkaline. [α] D25-86.5 ° (amazi), -60.4 ° (aside hydrochloric 5N). Ikwirakwizwa muri poroteyine zitandukanye. Aside amine ifite ingano iringaniye muri plankton yo mu mazi; Iboneka no mu mazi yo mu nyanja, mu bintu bito, no mu bisigazwa by'inyanja.
Proline ni aside amine idakenewe mu mubiri w'umuntu.
Imikorere n'intego
Gukoreshwa mu nganda zikora imiti
Imiti ya aside amine. Imwe mu miti fatizo yo gutera aside amine. Ikoreshwa mu kongeramo poroteyine nyuma yo kurya nabi, kubura poroteyine, indwara zikomeye zo mu gifu, ubushye, no kubagwa. Nta ngaruka mbi zigaragara z’uburozi.
Ingaruka zo mu mubiri
Mu binyabuzima, proline si ikintu cyiza cyo kugenzura osmoregulation gusa, ahubwo inakora nk'ikintu kirinda uturemangingo na enzymes, ndetse n'ikintu gikuraho radicals, bityo kikarinda imikurire y'ibimera mu gihe cy'ingufu za osmotic. Kugira ngo ikindi kintu cy'ingenzi cyo kugenzura osmoregulation kibe mu binyabuzima bifite potassium ion, proline ishobora kandi kugira uruhare mu kugenzura ikoreshwa rya cytoplasmic osmotic.
Porogaramu zo mu nganda
Mu nganda zikora synthesis, proline ishobora kugira uruhare mu gutera ingaruka zitangana kandi ikaba imbarutso ya hydrogenation, polymerization, n'ingaruka ziterwa n'amazi. Iyo ikoreshejwe nk'imbarutso ya izo ngaruka, igira imikorere ikomeye kandi ifite ubushobozi bwo gutandukanya ibintu.
Porogaramu mu zindi nzego
1. Proline n'ibikomoka kuri yo bikunze gukoreshwa nk'ibikatalisiti bingana mu bikorwa by'ibinyabuzima, aho kugabanuka kwa CBS n'ingaruka za aldol condensation ya proline ari ingero zikomeye.
2. Mu gihe cyo guteka, poroteyine ikungahaye kuri proline ihujwe na polyphenols, ishobora gutera ubushuhe (turbidity).
3. Ibikoresho fatizo byo gukora imisemburo ibuza imikorere y'uturemangingo tw'amabuye.
4. Ibintu biryoha, bikorana n'isukari binyuze mu gushyushya hamwe bigatera amatsinda ya amino hydrogen, bishobora gukora ibintu bifite impumuro zidasanzwe.
1. Uburambe bw'imyaka irenga 10 mu bijyanye n'ubuhanga bwa ISO,
2. Uruganda rukora uburyohe n'ibiryoshye, Ibirango bya Tianjia Own,
3. Ubushakashatsi ku bumenyi bw'isoko n'ikurikirana ry'imigendekere,
4. Gutanga no kwamamaza ku gihe ibicuruzwa bisaba amafaranga menshi,
5. Kwizerwa no gukurikiza neza inshingano z'amasezerano na serivisi nyuma yo kugurisha,
6. Inzobere mu bijyanye na serivisi mpuzamahanga z’ibikoresho, inyandiko zemewe n’amategeko n’inzira y’ubugenzuzi bw’umuntu wa gatatu.
