The role of lipids in mitochondrial electron transfer and oxidative phosphorylation

Phosphatidic Acid and Glyceride Synthesis by Particles from Spinach Leaves

“…In recent years, particularly in aninmals, much progress has been made (15 plant tissue we now have available consider-able knowledge concerning the lipi.d constituents but also a considerable ignorance concerning their metabolism, and the effect of their metabolism on subcellular particle function. Here we h.ave reported on some initial attempts to clarify some of the enzymic systems associated with lipid synthesis in spinach leaves.…”

Structural properties of phospholipids in the rat liver inner mitochondrial membrane. A 31P-NMR study

“…This is not only because of the demonstrated lipid requirement for oxidative phosphorylation to occur [1] and for function of individual components of the respiratory chain [2], but also because of a unique lipid composition. In particular, this organelle membrane is the only mammalian membrane containing (unsaturated) cardiolipin as a major lipid component [ 3].…”

Growth Response of Mycoplasma to Carotenoid Pigments and Carotenoid Intermediates

“…These dimensions are compatible with the width (3.54 of the electron transparent layer of the unit membrane of mycoplasmas as determined in ultrathin sections (van Iterson & Ruys, 1960), thereby presenting the proper space for the lengthwise orientation of the molecules across the unit membrane in the model proposed by Davson & Danielli (1952). Although the molecular dimensions of particles comprising the cell membrane as envisioned in the corpuscular theory (Benson, 1964) are not known, the lipid structure conceivably could lie across a hydrophobic area of the protein (Green & Fleischer, 1963) with the hydroxyl groups oriented a t the lateral surfaces. In either orientation, the hydroxyl groups would be available for enzymic reactions.…”
