Some synthetically obtained linear and cyclic phosphopeptides of low molecular weight have been studied by fast-atom bombardment and tandem mass spectrometry to verify the position of the phosphate group in these compounds. Based upon the occurrence/non-occurrence of loss of phosphoric acid from low abundance fragment ions induced by low- and high-energy collisions with target gases, it is shown that the position of the phosphate group in the phosphopeptides studied can be determined unequivocally.
通过快原子轰击和串联质谱对一些合成得到的低分子量线性和环状磷酸肽进行了研究，以验证这些化合物中磷酸基团的位置。基于与靶气体的低能和高能碰撞诱导的低丰度碎片离子中磷酸的丢失情况，结果表明所研究的磷酸肽中磷酸基团的位置可以明确确定。
