Spherosome Membranes: Half Unit-Membranes

AUTOR(ES)

Yatsu, L. Y.

RESUMO

Spherosomes are bounded by unusual single-line “membranes” which measure 2 to 3.5 nanometers in width, contrasted to the well known tripartite unit-membranes which measure 6 to 8.5 nanometers in over-all thickness. Juxtaposed externally (from the side addressing the hyaloplasm), two spherosomal membranes adjoin to form a thicker single line, but apposed internally (the sides that contact stored lipid) two single-line membranes touch to form a tripartite structure resembling a unit-membrane. Morphologically, we interpret the single-line membranes of spherosomes as half unit-membranes whose polar surfaces face the hyaloplasm and whose lipoidal nonpolar surfaces contact internal storage lipid.
