Abstract

Cytoplasmic structure has been reviewed several times during the long history of its study (e.g. 2, 1 8, 88, 90, 1 16). For the sake of brevity, and to avoid repetition, we merely provide an introduction to the literature on cytoplasmic structure for those who are unfamiliar with it, review some recent developments, and present a conceptual framework for future inves­ tigations. Throughout, we maintain a narrow focus on the structure of cytoplasm, neglecting such closely related fields as cellular locomotion and 0883-9 1 82/88/06 1 0-0369$02.00 369 LUBY-PHELPS, LANNI & TAYLOR intracellular particle transport. After a brief review of what is known about the biochemical composition and morphology of the cytoplasm, we discuss several models for the structure of the cytoplasm from the point of view of the physical chemistry of macromolecular solutions. Finally, we discuss the implications of recent findings for the understanding of cellular func­ tion. It is axiomatic that the kinetics and preferred mechanisms of biochemical processes are dependent on the properties of the medium in which they take place. In the case of the interdependent biochemical and biophysical processes that occur within the living cell, the ultimate medium is the cytoplasm, or the
