MICELLE Meaning and
Definition
-
A micelle is a small spherical aggregate or cluster of molecules that forms in a liquid solution. It is a crucial concept in chemistry and refers specifically to the self-assembly of certain amphiphilic molecules in aqueous media. Amphiphilic molecules have both hydrophilic (water-soluble) and hydrophobic (water-insoluble) parts in their structures. In an aqueous environment, such molecules tend to orient themselves spontaneously in a manner that minimizes the interactions between their hydrophobic portions and the water molecules. This collective behavior leads to the formation of micelles.
Within a micelle, the hydrophobic parts of the amphiphilic molecules are shielded and placed at the center, away from the surrounding water, while the hydrophilic portions are oriented towards the exterior, allowing for interaction with water molecules. This arrangement stabilizes the micelle structure. They can be visualized as tiny, spherical clusters where the hydrophobic tails are clustered together in the core, and the hydrophilic heads form the outer shell.
Micelles have diverse applications in various fields. In biology, they play a vital role in the transport and absorption of fats within the body. In industrial applications, micelles are used in cleaning agents, as they help solubilize hydrophobic substances and enhance the effectiveness of detergents. They also find use in drug delivery systems, where they can encapsulate hydrophobic drugs, enabling their transport through the bloodstream to target specific cells or tissues. Their unique structure and properties make micelles significant entities in many scientific disciplines.
Common Misspellings for MICELLE
Etymology of MICELLE
The word "micelle" has its origins in the late 19th century, specifically in the field of chemistry. It is derived from the Greek word "mikros", meaning "small" or "little". The suffix "-elle" is a diminutive ending, often used to indicate something small.
In chemistry, a micelle refers to a colloidal particle consisting of molecules or ions that are typically arranged in a spherical shape, with the hydrophilic (water-attracting) parts positioned toward the surface and the hydrophobic (water-repelling) parts in the inner core. The term "micelle" was coined to describe and categorize these small aggregations of molecules.
