Secondary proteins primarily refer to the structures formed by the folding of polypeptide chains into specific arrangements. The two main forms of secondary protein structures are alpha helices and beta sheets. Alpha helices are coiled structures stabilized by hydrogen bonds, while beta sheets consist of extended chains that can run parallel or antiparallel to each other, also stabilized by hydrogen bonds. These structures are crucial for the overall stability and function of proteins.
Collagen and keratin are examples of proteins in mammals that primarily exhibit only primary and secondary structures. Collagen is known for its triple helix structure, while keratin is a fibrous protein that forms alpha-helices and beta-sheets.
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.
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.

Complex carbohydrates, proteins and faty acids are secondary metabolites.
There are no known proteins such as helix proteins. Alpha helix is a secondary structure element found in proteins that formed by amino acids which can form helix. Other secondary structures are beta sheets and random coils.

Amino acids are the building blocks of proteins. A linked of amino acids greater than 50 is a polypeptide, which can be grouped into primary, secondary, tertiary and quaternary structures.
It is called secondary structure of proteins .
