Dinosaur peptides suggest mechanisms of protein survival. [PDF]
PLoS ONE, 2011 Eleven collagen peptide sequences recovered from chemical extracts of dinosaur bones were mapped onto molecular models of the vertebrate collagen fibril derived from extant taxa.

Pilot study on the effects of preservatives on corneal collagen parameters measured by small angle X-ray scattering analysis [PDF]
BMC Research Notes, 2021 Objective Small angle X-ray scattering (SAXS) analysis is a sensitive way of determining the ultrastructure of collagen in tissues. Little is known about how parameters measured by SAXS are affected by preservatives commonly used to prevent autolysis. We

The precipitation of toroidal collagen fibrils [PDF]
Biochemical Journal, 1969 The morphology of aggregates of calf-skin tropocollagen, precipitated by continuous injection into neutral phosphate buffers at 35°, has been studied by electron microscopy. Although most of the collagen is precipitated as normal native fibrils, a small proportion forms closed toroidal structures having the usual native band–interband pattern ...

Polymorphism of stable collagen fibrils [PDF]
arXiv, 2018 Collagen fibrils are versatile self-assembled structures that provide mechanical integrity within mammalian tissues. The radius of collagen fibrils vary widely depending on experimental conditions \textit{in vitro} or anatomical location \textit{in vivo}.

Collagen structure: Evidence for a helical organization of the collagen fibril [PDF]
Journal of Ultrastructure Research, 1977 The collagen fibrils of human or guinea pig dermis when exposed to the denaturing agents, urea or guanidine—HCl, dissociated into smaller, disparate subunits, probably aggregates of microfibrils. The process of dissociation demonstrates that the fibrils are assembled helically. Initially, diagonal clefts appear on the surface of the fibril.

Articular cartilage collagen: an irreplaceable framework? [PDF]
European Cells & Materials, 2006 Adult articular cartilage by dry weight is two-thirds collagen. The collagen has a unique molecular phenotype. The nascent type II collagen fibril is a heteropolymer, with collagen IX molecules covalently linked to the surface and collagen XI forming the

Glassy state of native collagen fibril [PDF]
EPL (Europhysics Letters), 2010 Our micromechanical experiments show that at physiological temperatures type I collagen fibril has several basic features of the glassy state. The transition out of this state [softening transition] essentially depends on the speed of heating v, e.g., for v=1 C/min it occurs around 70 C and is displayed by a peak of the internal friction and decreasing

Impact of Ultrasonication on the Self-Assembly Behavior and Gel Properties of Bovine Bone Collagen I
Molecules, 2023 This study deliberated the effect of ultrasonic treatment on collagen self-assembly behavior and collagen fibril gel properties. Bovine bone collagen I which had undergone ultrasonic treatment with different power (0–400 W) and duration (0–60 min) was ...
