Optical Rotation and Helical Polypeptide Chain Configuration in Collagen and Gelatin* by Carolyn

چکیده

Polarimetry has been used to detect the occurrence of configurational changes accompanying denaturation in various proteins (Jirgensons, 1950, 1951, 1952; Kauzmann el al., 1953; Yang and Foster, 1954; Linderstrf~mLang and Schellman, 1954). However, because of the present incomplete knowledge of protein structure, no concrete proposals have yet been made connecting observed rotational values and details of polypeptide chain configuration. The collagen-gelatin system is particularly suitable for such a correlation, since progress has been made in the interpretation of both the collagen wide-angle x-ray diagram (Bear, 1952; Pauling and Corey, 1953; Cohen and Bear, 1953) and the optical rotivity of gelatin (Robinson, 1953).

Optical Rotation and Helical Polypeptide Chain Configuration in Collagen and Gelatin

The optical rotation phenomena exhibited by a citrate-extracted fraction of ichthyocol (from carp swim bladder), as well as by the parent gelatin derived therefrom, have been studied. Dispersion data for all cases follow a single-term Drude equation, but the variations with state are adequately expressed by simple reference to changes in [alpha](D) as follows:- 1. The native collagen fraction, ...

Denatured collagen from the cuticle of Ascaris lumbricoides as a substrate for protocollagen proline hydroxylase.

Recent studies have shown that the hydroxyproline and hydroxylysine found in the collagen of vertebrates are synthesized by the hydroxylation of proline and lysine, which have been incorporated into a large polypeptide precursor of collagen called protocollagen. Because the collagen isolated from the cuticle of Ascaris lumbricoides contains less hydroxyproline and hydroxylysine than any other k...

Enhancement of the Magneto-Optical Kerr Effect in One- Dimensional Magnetophotonic Crystals with Adjustable Spatial Configuration

We studied magnetophotonic crystals (MPCs) with introduced magneticdefect layer sandwiched between magnetic and dielectric Bragg mirrors. Thesemagnetophotonic crystals have excellent capabilities to enhance reflection and Kerrrotation simultaneously. By adjusting spatial configuration such as repetition numbersof Bragg mirrors and thickness of magnetic defect layer, we a...

Hydrodynamic Properties of Gelatin – Studies from Intrinsic Viscosity Measurements

Gelatin is a natural polymer widely used in pharmaceutical, cosmetic, photographic, and food industries. It is obtained by denaturation and partial hydrolysis of fibrous collagen. Collagen is the most abundant structural protein of animals and by far the main organic component of skin and bone of vertebrates. However, collagen is standing for a family of proteins with 21 different types of amin...
