Phospholipids are water insoluble "building blocks" that define the membrane barrier surrounding cells and provide the structural scaffold and environment where membrane proteins reside. During the ...

Researchers have struggled to explain the molecular structure of proton exchange membranes, the key component in hydrogen fuel cells. Researchers have developed a model that explains how the membrane ...

A eukaryote is any cell or organism that possesses a clearly defined nucleus. Eukaryotic cells form the foundation of complex, multicellular life, including apple trees, mushrooms, fish and humans.

The cell is the structural and functional unit of living organisms. It was discovered by Robert Hooke in 1665. Cell in Latin means “little room”. Many organisms, such as bacteria, protozoa and yeasts ...

Cholesterol is one of the key molecules found in biomembranes, complex structures composed of proteins and lipids. It plays a crucial role in organizing the membrane and influencing the behavior of ...

Research Is Seeing the Emergence of Many Promising Techniques, Including Novel Sample Delivery Systems Membrane proteins, such as receptors, ion channels, and transporters, comprise nearly 30% of all ...

As power plants and energy stores, mitochondria are essential components of almost all cells in plants, fungi and animals. Until now, it has been assumed that these functions underlie a static ...

While prokaryotic cells do not have membrane-bound structures, they do have distinct cellular regions (Figure 1). In prokaryotic cells, DNA bundles together in a region called the nucleoid. Primitive ...

In nature, the cell membrane has a unique function of protecting the internal from the external environment and communicating outside by sensing the external chemical or physical stimuli like the most ...

MEMBRANES are a ubiquitous cell component responsible for controlling many vital cellular functions, including selective permeability, ion accumulation and conduction of nerve impulses. It is widely ...
