Kusifo se-maple syrup urine disease (MSUD), i-branched-chain L-amino (BCAA) kanye ne-2-oxo acids (BCOA) anqwabelana oketshezini lomzimba ngenxa yokuntuleka okuzuzwa njengefa lomsebenzi oyinkimbinkimbi we-branched-chain 2-oxo acid dehydrogenase.Ku-MSUD, ulwazi oluncane luyatholakala ngokubaluleka kokulahlwa komchamo kwezinhlanganisela ze-branched-chain.Sihlole ukucaciswa kwezinso kwe-leucine, i-valine, isoleucine ne-alloisoleucine, kanye nama-2-oxo acid ahambisana nawo 4-methyl-2-oxopentanoate (KIC), 3-methyl-2-oxobutanoate (KIV), (S) - (S- KMV), kanye (R) -3-methyl-2-oxopentanoate (R-KMV), besebenzisa amasampula e-plasma nomchamo (n = 63) kusuka kuziguli ze-10 ezine-MSUD yakudala.Ukukhishwa kwe-fractional renal ye-BCAA yamahhala bekusebangeni elijwayelekile (<0.5%) futhi kuzimele ekugxilweni kwe-plasma.I-excretion of bound (N-acylated) BCAA yayijwayelekile futhi ingancikile kakhulu ekugxilweni kwe-plasma ye-BCAA.Ukukhishwa kwezinso okuyingxenyana kwe-BCOA bekukuhlelo lwe-KIC << KIV < R-KMV < noma = S-KMV (ububanzi (%): KIC 0.1-25; KI V 0.14-21.3; S-KMV 0.26-24.6; R- I-KMV 0.1-35.9), ehlotshaniswa kakhulu nokugxilwa kwe-plasma ye-KIC, futhi ngokuvamile iphakeme kunaleyo ye-BCAA ehlobene.Imiphumela ibonisa ukuthi ukukhishwa kwezinso kwe-BCAA yamahhala kanye nokuphuma kwe-acylated kuyinto encane.Ukukhishwa kwezinso kwe-BCOA, nokho, ngokwezinga elithile kumelana nokwenyuka kokugxila kwe-BCAA futhi ngaleyo ndlela kunomthelela ekwehliseni inani lamachibi e-BCAA ku-MSUD.
