ʻO Fmoc-Gln-OH(Fmoc-Gln-OH) he ʻakika amino me nā waiwai penei:

 

ʻAno:

-Ke kimeka: C25H22N2O6

-Molecular kaumaha: 446.46g/mol

-Nani: Keʻokeʻo a aneane keʻokeʻo keʻokeʻo a pauka paha

-Solubility: Fmoc-Gln-OH hiki ke hoʻoheheʻe ʻia i kekahi mau mea hoʻoheheʻe organik, e like me ka dimethyl sulfoxide (DMSO) a i ʻole N,N-dimethylformamide (DMF).

 

E hoʻohana:

-Nā noiʻi biochemical: Hiki ke hoʻohana ʻia ʻo Fmoc-Gln-OH ma ke ʻano he hui pale i ka synthesis paʻa paʻa no ka peptide a i ʻole synthesis protein.

-Hoʻomohala Lapaʻau: Hiki ke hoʻohana ʻia ʻo Fmoc-Gln-OH ma ke ʻano he waena i ka synthesis o nā lāʻau lapaʻau a i ʻole nā ​​peptides biologically active.

 

Kaʻina hoʻomākaukau:

ʻO ka hoʻomākaukau ʻana o ka Fmoc-Gln-OH hiki ke hoʻokō ʻia e nā pae aʻe:

1. ʻO ka mua, hoʻopili ʻia ka glutamine me ka fluoric anhydride (Fmoc-OSu) e loaʻa ai ka Fmoc-Gln-OH acid fluoride (Fmoc-Gln-OF).

2. A laila, hoʻopili ʻia ka Fmoc-Gln-OF me ka pyridine (Py) a i ʻole N,N-dimethylpyrrolidone (DMAP) ma lalo o nā kūlana kumu e hoʻohua ai i ka Fmoc-Gln-OH.

 

ʻIke palekana:

-ʻO ka Fmoc-Gln-OH maʻamau palekana ma lalo o nā kūlana hana maʻamau, akā pono nō e hoʻokō i nā kaʻina hana palekana.

-E makaʻala e pale aku i ka pili ʻana me ka ʻili, nā maka a i ʻole nā ​​​​membrane mucous, a pale i ka inhalation a i ʻole ka ʻai ʻana.

-I ka wā e hoʻohana ai, hiki iā ʻoe ke hoʻohana i nā lako pale pilikino kūpono, e like me nā mīkina lima laboratory, nā aniani palekana a me nā lole ʻoihana.

-Ina pilikia a pilikia paha, e imi i ke kokua lapaau i ka manawa a e lawe mai i ka 'ike kiko'ī e pili ana i nā kemika no ka 'ike.
