The collagen molecule, also known as the “tropocollagen”, is part of larger collagen aggregates such as fibrils. The whole molecule is approximately 300 nm long and 1.5 nm in diameter.

Collagen, the body's most abundant protein, has long been viewed as a predictable structural component of tissues. However, a new study led by Rice University's Jeffrey Hartgerink and Tracy Yu, in ...

A new study by researchers at the University of Rochester, published in Biophotonics Discovery, suggests that differences in the structure of collagen—the main protein in connective tissue—may ...

The involvement of collagen in bone biomineralization is commonly admitted, yet its role remains unclear. Here we show that type I collagen in vitro can initiate and orientate the growth of ...

Scientists in Anant Madabhushi 's lab have used artificial intelligence (AI) to identify new biomarkers for breast cancer that can predict whether the cancer will return after treatment—and which can ...

Collagen types I, II, III, V and XI self-assemble into D-periodic cross-striated fibrils. Here the D is approximately 67 nm and there is characteristic axial periodicity of collagen.

Collagen Structure: The researchers used advanced cryo-electron microscopy (cryo-EM) to determine the atomic structure of a packed collagen assembly that deviates from the traditionally accepted ...
