The introduction of intramolecular cocalent cross-linkages into ichthyocol tropocollagen with monofunctional aldehydes.
The presence of covalent cross-linkages between the peptide chains of collagen has been postulated to account for many of the properties of collagen (l), particularly the insolubility of mature fibrous mammalian collagen in water or dilute acids at low temperature. There is as yet no direct chemical evidence as to the nature and number of the cross-linkages, although ester bonds (2-4) and aldeh...

15 صفحه اولUptake of 13-hydroperoxylinoleic acid by cultured cells.
Oxidized free fatty acids have profound effects on cultured cells. However, little is known about whether these effects depend on their uptake and metabolism by cells or primarily involve their interaction with cell-surface components. We determined the uptake and metabolism of unoxidized (linoleic or oleic acid) and oxidized linoleic acid (13-hydroperoxyoctadecadienoic acid, 13-HPODE) by endot...
متن کاملAldehydes in cigarette smoke react with the lipid peroxidation product malonaldehyde to form fluorescent protein adducts on lysines.
Cigarette smoke is a risk factor for the development of several diseases, but the exact mechanism responsible has not been well-characterized. Because modification, or adducting, of biomolecules is thought to mediate the toxic effects observed from exposure to a wide variety of harmful chemicals, this study investigated the ability of cigarette smoke to produce specific adducts on a peptide to ...
