The primary structure of a protein — its amino acid sequence — drives the folding and intramolecular bonding of the linear amino acid chain, which ultimately determines the protein's unique three-dimensional shape.

Folded proteins are stabilized by thousands of noncovalent bonds between amino acids." - Google.
The fibrous proteins which are found in connective tissues of the animals are either collagen, elastic, or reticular fibers. This collagen fibers provide strengths to the connective tissues.
