In this work, a hypothesis is presented that could explain the non‐homogeneous lateral distribution of membrane components in Golgi vesicles. It is shown that the non‐homogeneous lateral distribution of membrane components and the specific flattened shape of Golgi vesicles are strongly coupled. In agreement with experimental evidence, it is indicated that some of the membrane components may be concentrated mainly on the curved bulbous rims of the Golgi vesicles, while the other components are distributed predominantly in their flat central part.
