thiohydantoin 中文意思是什麼
thiohydantoin
解釋
海硫因-
However, due to the poor reactive carboxyl group of c - terminus, it is difficult to derivatize peptides topeptidyl t hiohydantoins for c - terminus, and the schlack - kumpf degradation based on thiohydantoin procedure has not yet been developed to such an efficient method as edman degradation
然而，由於c端羧基的化學性質不活潑，致使schlack - kumpf降解法的研究進展緩慢。但通過近十年的研究表明該方法是很有希望成為常規c端順序測定的方法。 -
Mass spectrometry technique will play more and more role in the field of sequence analysis. standard amino acid thiohydantoins are required as reference standard for development of c - terminal protein sequencing based on the thiohydantoin procedure
在蛋白質c端（異）硫氰酸法順序測定技術中，標準氨基酸乙內酰硫脲（ th - aa ）的制備是必須首先要解決的問題。 -
All of 19 amino acid thiohydantoins were synthesized by using free amino acids as starting materials, acetic anhydride as the carboxyl group activating reagent and tms - itc as the derivatizing reagent. the proiine thiohydantoin was prepared by using ammonium thiocyanate ( n114scn ) as the derivatizing reagent
本文以l -氨基酸為原料，採用乙酸酐作活化試劑， tms - itc作為偶聯試劑，制備了19種th - aa ，另外th - pro的制備是用nh _ 4scn作為偶聯試劑獲得成功的。
