“…Measurements of the viscosity of red blood cell suspensions have led to the suggestion of a very low surface viscosity for the membrane (ca. 10-6 surface poise) (Dintenfass, 1964(Dintenfass, , 1969. In the alveolar membranes of the poikilothermic eukaryote Tetrahymena, there is a temperaturedependent particle aggregation (Speth and Wunderlich, 1973).…”

“…Subsequently, with further depletion, a reversible ATP-dependent solgel transformation occurs at the membrane interior interface. Dintenfass (54) has suggested that changes at such an interface may contribute to cellular viscosity. Subcortical sol-gel transformation may lead to a degree of structural organization which decreases membrane deformability and dictates the disc-sphere transformation as well as increasing viscosity and decreasing filterability of the depleted cell.…”

“…At the present time the role of liquid crystals in biological systems has only begun to be realized. In papers by Chapman and B y r n e (3), Luzzati and Husson (4), Cope (5), and Dintenfass (6) studies have been made of liquid crystalline materials which are found in biological systems. More recently Stewart (7) has summarized the role of liquid crystals in vivo.…”

Most lipids do not pass, on heating, directly from a crystalline structure to an isotropic structure. They are often characterized by a number of intermediate phases, ranging from the plastic crystal, where the center of gravity of the molecule may rotate about one or more axes while the three‐dimensional order of the crystal remains, to nematic liquid crystals, which have birefrigent properties of crystals and yet are characterized by completely random ordering of the molecular centers. The smectic and cholesteric liquid crystalline structures are most commonly encountered in lipids. The structural characteristics of these systems are discussed. Of particular interest in living systems are liquid crystals, which are formed by cholesteric esters and many protein materials, and the two‐dimensional crystals (smectic structure), which are formed by fatty acid derivatives. The mechanisms of energy transfer and the mechanical alignment in these liquid crystalline systems are unique and require different considerations from those found adaptable to liquids or solids. The properties of liquid crystals which might best be associated with living systems will be discussed, including surface properties and diffusivity.
