Gránulo

Gránulo is a term with various meanings depending on the context. In biology, a gránulo often refers to a small granule or particle found within a cell. These cellular granules can contain a variety of substances, such as pigments, enzymes, or secretory products, and play important roles in cellular function. For example, in leukocytes, granules contain enzymes essential for immune defense.

In pharmacology, gránulo can refer to a medicinal formulation in the form of small particles or granules. These are often designed for oral administration, offering advantages in terms of ease of swallowing and controlled release of the active ingredient. Granulated medications can also be easier to dissolve or disperse.

The term also appears in geology, where gránulo might describe a granular texture in rocks. This texture indicates that the rock is composed of numerous small, distinct mineral grains. The size and shape of these grains can provide clues about the rock's formation and history.

In everyday language, gránulo simply means a small grain or particle of any substance. It can be used to describe anything from a grain of sand to a small lump of sugar. The fundamental concept across these different fields is that of a discrete, small particle.
