Nuclear Envelope

The nuclear envelope is an important part of the cell membrane, which is a layer of intercellular substance located between the cell and the environment. It plays an important role in providing cell structure and function, as well as regulating interactions between cells in the body.

The nuclear envelope is made up of several components, including:

lipid bilayer (double lipid layer), which forms a barrier to the penetration of toxic substances and infection; protein complex located on the inner side of the membrane; macromolecular complex (macromolecular complex),

The nuclear envelope is a special layer of epithelial cells that surrounds the nucleus and protects it from damage and external influences. The nuclei of cells are located inside the cytoplasm, which is the internal environment of the cell and contains various organelles and structures. The nuclear envelope consists of two main layers - the outer membrane and the inner membrane. The outer membrane is a protein layer consisting of complex proteins and glycoproteins that protect the nucleus from damage and regulate the metabolism between the nucleus and the cytoplasm. The inner membrane is also a protein-lipid complex and transmits signals from the cytoplasm and back to the nucleus. Between the outer and inner membranes is the perinuclear zone, a free space that can contain various molecules and factors, including ribosomes, enzymes and lysosomes.

Functions of the nuclear membrane. Important functions of the nuclear envelope are its structural role, the function of protecting the nucleus from damage and the regulation of interaction
