At physiological temperatures, cell membranes are fluid; at cooler temperatures, they become gel-like. Scientists who model membrane structure and dynamics describe the membrane as a fluid mosaic ...

David Baker, Demis Hassabis and John M. Jumper revealed how amino acids shape protein structure, a finding that could aid in ...

Bacteria that cause diseases, so-called pathogens, develop various strategies to exploit human cells as hosts to their own ...

The cell wall surrounds the plasma membrane and provides the cell tensile strength and protection. Plant cells have some specialized properties that make them distinct from animal cells.

Cell structure Description Function Cell type Cell wall Freely permeable layer surrounding cell membrane. The cell wall of plant cells is made from cellulose. This gives them a rigid structure.

But understanding the structure and interactions of cholesterol in biomembranes has been a longstanding obstacle for ...

Researchers at Forschungszentrum Julich have now used cryo-electron microscopy to uncover intriguing new information. Known from the photosynthetic system of plants, algae, and bacteria, the membrane ...

The membrane that surrounds cells in living organisms is extremely flexible and sensitive. How it protects itself from damage ...

Researchers used Raman spectroscopy to study cholesterol in cell membranes, discovering unique structural variations. This ...

The black widow spider is one of the most feared spider species. Its venom is a cocktail of seven different toxins that ...

Transport proteins are responsible for the ongoing movement of substrates into and out of a biological cell. However, it is difficult to determine which substrates a specific protein can transport.

In a move akin to puncturing an egg yolk without breaking the shell or egg white, researchers have figured out how to pierce ...
