What type of protein consists of a repetitive amino acid sequence?

The type of protein that consists of a repetitive amino acid sequence is fibrous protein. Fibrous proteins are characterized by their elongated, strand-like structures and the repetition of specific amino acid sequences. This repetitive nature contributes to their structural role in various biological functions, primarily in providing strength and support to cells and tissues.

Fibrous proteins, such as collagen and keratin, play crucial roles in connective tissues, skin, hair, and nails. Their repetitive sequences and specific folding patterns lead to the formation of stable structures that can withstand tension and provide mechanical support.

In contrast, globular proteins are more compact and typically have diverse functions as enzymes, antibodies, or transport proteins. Dynamic and metabolic are not formal categories of protein structure; instead, they might refer to the roles or actions of certain proteins but do not characterize the structure based on amino acid sequence specificity.
