Thermal Phase Transitions in Biomembranes,id-crystalline lamellar phase which phospholipids exhibit in excess water. Much of the membrane protein was assumed to be bound on each side to the polar ends of the lipid molecules. Although this bilayer concept, with minor modifications, is the most commonly accepted model for membrane structure,

Biopolymerization of Peptide Antibiotics, acid (6-APA) contained traces of a macromolecular proteinaceous residue with striking allergenic properties in human subjects. Efforts were then made in the laboratory to remove these residues, but were only partly successful, because of the formation by penicillin in solution of a second residue w

The Use of Slightly Soluble, Non-Polar Solutes as Probes for Obtaining Evidence of Water Structure,ared to solubility behavior for ideal and for regular solutions. The explanations for the abnormal solubility behavior have involved considerations of enthalpy and entropy changes which have been attributed to iceberg formation, the mixing of molecules, and intermolecular interactions. From their an

This observation has stimulated a large body of investigation of the dilute solution properties of this class of polymers. In more concentrated polypeptide solutions (in the range of ten to fifty p

Several considerations influence the choice of the dye in such conjugates: extinction coefficient, lifetime, effect of pH, and interaction with the macromolecule to which it is coupled. Fluorescein has a higher molar extinction coefficient (3.4 × 10.) than

Structural Studies of the Cholesteric Mesophase, liquid crystals (34). The cholesteric mesophase is unique in that it can scatter white light to form brilliant colors. Nearly all cholesteric substances are esters of cholesterol. These compounds have a negative optical activity with an unusually large rotation. This large rotatory power is due to
