Nature, 1954
AN arrangement of three non-coaxial helical chains linked to one another by hydrogen bonds approximately perpendicular to the length of the chains was suggested as the basis of the structure of collagen two years ago1. This structure explained the occurrence of a fraction of more than one-third of glycine residues and could readily accommodate proline ...

PAST work on monolayers of gelatin on water has generally led to the conclusion that it is not suitable for such studies because of its high solubility1. This difficulty has been overcome with other proteins by spreading on strong solutions of ammonium sulphate2, and we have found that stable monolayers of collagen can be formed on 30 per cent ammonium

Digestive Endoscopy, 2012
In the present paper, we report a case of rare collagenous gastritis. The patient was a 25‐year‐old man who had experienced nausea, abdominal distention and epigastralgia since 2005. Esophagogastroduodenoscopy (EGD) carried out at initial examination by the patient's local doctor revealed an extensively discolored depression from the upper gastric body

Clinics in Plastic Surgery, 2001
Injectable collagens (e.g., ZC-I, ZC-II, ZP) provide the physician with a manner for approaching mild contour defects. They are a temporary, biocompatible solution to many, but certainly not all, soft-tissue deficiencies. The adverse reaction profile is of an acceptably low level and indeed only of local significance.

Annual Review of Food Science and Technology, 2015
Collagen and gelatin have been widely used in the food, pharmaceutical, and cosmetic industries due to their excellent biocompatibility, easy biodegradability, and weak antigenicity. Fish collagen and gelatin are of renewed interest, owing to the safety and religious concerns of their mammalian counterparts.

Electrospinning of collagen nanofibers.
Biomacromolecules, 2002Electrospinning is a fabrication process that uses an electric field to control the deposition of polymer fibers onto a target substrate. This electrostatic processing strategy can be used to fabricate fibrous polymer mats composed of fiber diameters ...

Bone Collagen Quality Indicators for Palaeodietary and Radiocarbon Measurements
, 1999The quality of bone collagen extracts is central to the14C dating and isotope palaeodietary analysis of bone. The intactness and purity of the extracted gelatin (“collagen”) is strongly dependent on the extent of diagenetic degradation, contamination and

Advanced Collagen‐Based Biomaterials for Regenerative Biomedicine
Advanced Functional Materials, 2018In recent decades, collagen is one of the most versatile biomaterials used in biomedical applications, mostly due to its biomimetic and structural composition in the extracellular matrix (ECM).

International Journal of Peptide and Protein Research, 1988
This review article, based on a lecture delivered in Madras in 1985, is an account of the author's experience in the working out of the molecular structure and conformation of the collagen triple‐helix over the years 1952–78. It starts with the first proposal of the correct triple‐helix in 1954, but with three residues per turn, which was later refined
