Amylose is a ______ chain.

Explanation:
Amylose is a linear chain of glucose units linked by α-1,4 glycosidic bonds. Because there are no branches (no α-1,6 linkages), the polymer remains unbranched, forming a flexible linear backbone that can coil into a helical structure in solution. This stands in contrast to amylopectin, which is branched due to additional α-1,6 linkages. Cyclic or zigzag aren’t the typical ways we describe the amylose backbone; the most accurate descriptor is linear (unbranched).
