Particles (the disperse phase) suspended in a second medium (the dispersion medium); can be solid, liquid or gas suspended in a solid, liquid or gas.
Fine particles suspended in a liquid or solid.
Gooey substances, usually proteins and starches, whose molecules can hold large amounts of a solvent (usually water) without dissolving. In lifeforms, virtually all fluids are held suspended in protein or starch colloids (hydrogels). (Examples: cell protoplasm, lime Jell-0.)
A mass of tiny particles of one substance dispersed in another substance.
The particles which are suspended in a colloid.
A thick jelly-like substance which stores hormones, produced in the thyroid gland.
Non-crystal- line substance consisting of microscopic particles, often large single molecules, dispersed throughout a second substance such as a gel or liquid. Also refers to the gelatin-like substance of the thyroid gland that contains thyroid hormone.
A type of suspension, for instance milk, in which insoluble particles are suspended in a fluid. In medical parlance a colloid preparation is one containing plasma proteins and is used to treat patients in shock. The follicles of the thyroid gland also contain a colloid substance.
A gluelike substance, such as a protein or starch, whose particles (molecules or aggregates of molecules), when dispersed as much as possible in a solvent, remain uniformly distributed and do not form a true solution.
A material that disperses particles within a medium can be defined as a substance with the ability to achieve such dispersion. In the context of film emulsion, the gelatin employed can be accurately described as a colloid, signifying its role in effectively dispersing the constituent particles.
A colloid is a type of fluid that shares similarities with a suspension, which consists of insoluble particles suspended in a liquid. However, colloid particles are smaller and lighter, requiring high-speed centrifugation for separation from the liquid. In the field of medicine, plasma proteins are isolated from blood and occasionally utilized in colloid formulations for the treatment of shock.
The term “colloid” is also used to describe a substance present in the thyroid gland that consists of proteins.
A uniform, jelly-like material made up of large molecules or clusters of small molecules distributed in a different medium. For instance, a solid can be dispersed in a liquid, as seen in protoplasm. Unlike true solutions, colloids can’t pass through semi-permeable cell membranes.
