title: Investigation of total, free, peptide-bound, protein-bound, soluble and insoluble collagen hydroxyproline content in tissues from the Arabian camel (Camelus dromedarius).
abstract: This study was conducted to determine the concentration of total, free, peptide-bound, protein-bound, soluble and insoluble collagen hydroxyproline (Hyp) in tissues from the Arabian camel (Camelus dromedarius). Results indicated that there were significant differences in the concentration of total, free, peptide-bound, protein-bound, soluble and insoluble collagen Hyp in various tissues (P < 0.01). Camel kidney showed a significantly high concentration of total, free, peptide-bound and protein-bound Hyp and collagen content as compared to other tissues examined (P < 0.01). Kidney also showed a significantly high concentration of soluble collagen Hyp as compared to other tissues examined (P < 0.01). However, the concentration of insoluble collagen Hyp was significantly high in liver when compared to other tissues (P < 0.01). These variations may result from differences in the collagen structure and/or composition in this species.
