Keratin
Most proteins in mammals have tertiary and quaternary structures in addition to primary and secondary structures. However, some small proteins or peptides, such as certain antimicrobial peptides, may exist in nature with only primary and secondary structures, lacking the more complex tertiary and quaternary arrangements.
Proteins in urine are typically in their primary structure, which is the linear sequence of amino acids. Secondary and tertiary structures may be disrupted due to the conditions in the urinary tract. Significant alterations in structure can indicate health issues such as kidney damage or proteinuria.
They have different primary, secondary, tertiary, and quaternary structure.
The vascular cambium produces secondary xylem (wood) and secondary phloem, which are formed in a lateral direction. These structures are produced between the primary xylem and primary phloem in stems and roots of plants. The secondary xylem is produced toward the interior, while the secondary phloem is produced toward the exterior, contributing to the increase in girth of the plant.
Keratin is a protein, so it has both a primary and secondary structure. In fact, all proteins have a primary and secondary structure, along with a tertiary and quaternary structure. There are many different ways proteins can be structured and shaped, so biochemists divide proteins into 4 separate parts or structures.

Proteins?
Proteins in urine are typically in their primary structure, which is the linear sequence of amino acids. Secondary and tertiary structures may be disrupted due to the conditions in the urinary tract. Significant alterations in structure can indicate health issues such as kidney damage or proteinuria.
Proteins *have* primary, secondary, tertiary, and quarternary structures. The primary structure is simply the chain of amino acids without any other structure. Secondary structure results from folding of the chain to form rudimentary structures such as alpha helices, beta sheets and turns. Tertiary structure results from the further folding of the protein with secondary structures into different 3D shapes by interactions between different parts of the secondary structure. Quarternary structure results from different proteins with tertiary structures coming together to form a protein complex.

If meaning the four structural levels in proteins, then these are:* Primary structure, which is the sequence of amino acids in the peptide chain that constitutes the protein. * Secondary structure, is the location of formations called alpha-helices, beta-sheets and coiled coils (undefined, flexible structure), that forms with the help of hydrogen bonds between amino acids. * Tertiary structure: This is the over-all fold/structure of one peptide chain/protein, which can consist of many so called "domains" of typical structures of alpha-helices and beta-sheets. * Quaternary structure: Because some proteins are formed from many smaller subproteins (that is, by many peptide chains), quaternary structure describe how these subunits are assembled together.
Sorry, I want to know the difference between Primary, Secondary and Tertiary structure of aircraft

Proteins can form structures such as a helix or a sheet due to the specific arrangement of amino acids in their sequence. The hydrogen bonding between the amino acids in the polypeptide chain determines the secondary structure of the protein, leading to the formation of helices and sheets.
2011: 10.1% primary, 46.8 secondary, 43.1 tertiary
They have different primary, secondary, tertiary, and quaternary structure.
