glòbul

Glòbul is the Catalan term for a small, rounded particle or cell, derived from Latin globulus. In biology and medicine it denotes a tiny, spherical body, often visible only under a microscope. The term is generic and used across disciplines to refer to any compact, rounded particle.

In physiology, glòbul vermell (red blood cell) and glòbul blanc (white blood cell) are common examples where the word denotes blood cells. In cellular biology, glòbul can also refer to vesicle-like structures inside cells, such as lipid globules that store fats or various secretory granules.

In chemistry and materials science, glòbul can describe colloidal spheres, pigment globules in emulsions, or microbeads used in chromatography and diagnostics. The size of a glòbul can range from a few nanometres (for protein or lipid globules) to several micrometres (for cells or synthetic beads).

Notable notes: The term is general and context is essential to specify the type of glòbul; when precision is needed, compound terms such as glòbul vermell, glòbul blanc, or lipid globules are used.
