Chemical modification of glycopeptides and prediction of their retention on hydrophilic liquid chromatography
Pála, Anastasie ; Ječmen, Tomáš (advisor) ; Křížek, Tomáš (referee)
5 Abstract Glycoproteins are an integral part of many cellular processes, without which the complex life of higher organisms wouldn't be possible. Glycoproteins are also important from clinical perspective, since changes of physiological state caused by diseases lead to changes in protein glycosylation. Changes in the abundance of glycosylations or structures of synthesised glycans are associated with diseases such as Alzheimer's disease or cancer and as such can be used as biomarkers for diagnostic purposes. There are several approaches used in the study of glycoproteins, one of which is glycopeptide analysis of enzymatically cleaved glycoproteins. This approach allows analysis of glycoproteins even in complex matrices such as biological samples, as the glycan residues are still connected to their glycosylation sites. This makes the identification of glycoproteins along with their associated glycan structures possible, which oftentimes isn't possible with other analytical approaches. Glycopeptide analysis readily uses high performance liquid chromatography coupled with mass spectrometry. Hydrophilic interaction chromatography is often chosen as the separation mode for glycoproteomic studies, due to its ability to separate glycopeptides with different glycans attached. This chromatographic mode was used in...
