A Study of the Distribution of Total, Free, Peptide-bound and Protein-bound Hydroxyproline in the Plasma of Arabian Camel (Camelus dromedarius)

This study was conducted to determine the presence of total, free, protein bound and peptide bound hydroxyproline (Hyp) in the plasma of the Arabian camel (Camelus dromedarius) as compared to the sheep. Results showed that the Hyp pool of sheep plasma was composed of free, protein bound and peptide bound hydroxyproline. On the other hand, only free and protein bound Hyp contributed to the Hyp pool of the camel plasma; peptide bound Hyp was not detected. Camel plasma showed a significantly lower content of total Hyp (p
