Ultraviolet absorption spectra of proteins and amino acids.
This chapter deals with the absorption spectra of proteins and amino acids, principally derived from the study of homogeneous absorbing systems, in which the inhomogeneity is finer in grade by several orders than the dimensions of the exploring light beam. Expand
A spectroscopic study of the haemin--human-serum-albumin system.
The interaction of haemin with human serum albumin has been reexamined, and it is suggested, on the basis of an interaction of albumin with iron-free protoporphyrin IX, that the iron is not implicated in the interaction with the protein. Expand
Formation and structure of gels and fibrils from glucagon.
The kinetics of the aggregation have been followed by viscometry, and are found to exhibit a sigmoidal profile with a long lag phase, associated with the formation of nuclei for polymerisation, demonstrated by the elimination of the lag when fresh solutions are seeded with a preformed glucagon gel.

Properties of the high-molecular-weight protein (spectrin) from human-erythrocyte membranes.
The high-molecular-weight protein component from human erythrocytes has been isolated and its solubility properties studied and is similar to the starting material in its circular dichroism, in its pH-precipitation profiles, and the manner in which the latter is modified by calcium ions. Expand
Binding of protoporphyrin and haemin to human spectrin.
At ionic strengths near physiological the authors can find no evidence of binding of haemoglobin to spectrin, as judged by sedimentation velocity, and it appears that reported interactions of this nature represent only non-specific binding at low ionic strength. Expand
An examination of the soluble oligomeric complexes extracted from the red cell membrane and their relation to the membrane cytoskeleton.
The results lead to inferences concerning the mechanism of dissociation of the network from the membrane, suggested that the complexes represent intact junctions of the membrane cytoskeletal network. Expand
The Reduction of Vitamin B12
Two distinct reduction products of vitamin B12 have been described in the literature, by Diehl and Murie1 and by Boos, Carr and Conn2; we shall refer to these as I and II respectively. They differ inExpand
