Tendons diffraction patterns

Fio. 8. Wide-angle X-ray diffraction patterns of collagen from rat tail tendon (o) unstretched (h) stretched 8%. (From Randall, 1954.)... [Pg.42]

Fig. 14. Small-angle X-ray diffraction pattern of kangaroo tail tendon. Layer line indices are indicated. Note the fanning seen in h and c. This is indicative of a certain amount of chain distortion which accompanies drying (a) moist specimen (b) after soaking in water for 2 months, then drying under tension (e) after brief exposure to water, then drying under tension. (From Bear et al., 1951.)... Fig. 14. Small-angle X-ray diffraction pattern of kangaroo tail tendon. Layer line indices are indicated. Note the fanning seen in h and c.

Besides the x-ray diffraction patterns characteristic of the alpha- and beta-type proteins, there is a third kind that of collagen, the protein of tendon and skin. On the primary level, collagen is characterized by a high proportion of proline and hydroxy proline residues, and by frequent repetitions of the sequence Gly.Pro.Hypro. The pyrrolidine ring of proline and hydroxyproline can affect... [Pg.1159]

In the period around 1920, x-ray diffraction patterns of silk, hair, muscle, tendon, and other fibrous proteins were first made, and the surmise (later verified) was advanced that in silk fibroin the protein molecules are in an extended configuration, as shown in the preceding drawing. [Pg.112]

One of the major applications of chitosan is based on its ability to bind strongly to metal ions. Immersing a tendon chitosan in various metal salt solutions such as Cd +, Cr +, Hg +, Pb +Zn2+, or Cu + ions give x-ray diffraction patterns where the primary amino group is one of the ligand. All crystals known so far were indexed with the orthorhombic unit cell. The conformational pattern of chitosan chain was identical to the tendon form of chitosan. [Pg.92]

Small angle X-ray- and neutron-diffraction patterns obtained for the annulus fibrosus of porcine invertebral disc have highlighted differences between the collagen in this tissue and that in tendon. ... [Pg.142]

Mammalian tendons are readily available and provide the best degree of fibrillar orientation. Patterns obtained from them (Figs. 3 and 7) permit observation of the maximum number of diffractions. Instead of tracing the historical development of the subject, this discussion is based on data obtained from the best patterns available to the author. Table IV shows the average measurements for the positions of individual spot... [Pg.113]

The x-ray fiber diffraction data of chitosan was first derived from the solid-state deacetylated product of a lobster tendon chitin by Clark and Smith (1936). Sixty years later, Okuyama et al. (1997) analyzed the pattern of tendon chitosan. In the tendon polymorph, the chitosan chains and water molecules are packed in an orthorhombic unit cell. Each chitosan chain takes an extended... [Pg.89]
