Question

Quizplus · Accepted Answer

Fibrous proteins are characterized by their highly elongated, rod-like structures that are organized approximately parallel along a single axis. This arrangement allows for the formation of long fibers or large sheets, which is a defining feature of fibrous proteins. While some fibrous proteins may contain an abundance of aromatic or hydrophilic amino acids, this is not a universal feature of all fibrous proteins. The repeating (-a-b-c-d-)_n sequence is a characteristic of collagen, one type of fibrous protein, but not all fibrous proteins share this sequence.
