What is the difference between actual structure and structural form?

Actual structure refers to the physical arrangement and organization of components within a system, such as the tangible elements in a building or the real components in a chemical compound. In contrast, structural form is a more abstract concept, focusing on the theoretical or conceptual framework that defines how those components interact and function together. Essentially, actual structure is the concrete manifestation, while structural form represents the underlying principles or designs that guide that manifestation.
