Does Keratin Have A Tertiary Structure? Based upon their tertiary structure, proteins are often divided into globular or fibrous types. Fibrous proteins, like α-keratin, have elongated rope-like structures that are strong and hydrophobic. Globular proteins, like the plasma proteins and the immunoglobulins, are more spherical and hydrophilic.
What level of structure is keratin? α-keratin is a fibrous structural protein, meaning it is made up of amino acids that form a repeating secondary structure. The secondary structure of α-keratin is very similar to that of a traditional protein α-helix and forms a coiled coil.
Is keratin secondary or tertiary structure? α-keratin is a fibrous structural protein, meaning it is made up of amino acids that form a repeating secondary structure.
