Structures of the D-galactose oligosaccharides from earthworm cuticle collagen.
Earthworms have a thin layer of cuticle which covers the whole body and serves as a general protective function. This cuticle has the characteristic wide angle x-ray diffraction pattern of collagen (1, 2) and has an amino acid composition characteristic of collagen (3). Much of the dry weight of this cuticle can be extracted by neutral salt or weak acid and purified as a collagen (4, 5). Earthw...
متن کاملSoluble Earthworm Cuticle Collagen: a Possible Dimer of Tropocollagen
When soluble earthworm cuticle collagen molecules are subjected to the shearing forces of a flow birefringence instrument, they are broken into particles approximately half the original size. The broken particles resemble vertebrate tropocollagen molecules in their hydrodynamic properties, in levorotatory powers, and in their appearance in the electron microscope. Most significantly, the broken...
