Proteins are the main structural element that build the body. Actin, filamin, collagen, myosin are some important proteins that build cells and tissues of animals. they are normally fibrous in nature so as they found mostly in fibrous tissues such as tendons, ligaments, bones and so on.

TaigaThe functional unit of protein structure is the polypeptide chain. This chain is made up of amino acids linked together by peptide bonds, forming the primary structure of the protein. The unique sequence of amino acids in the polypeptide chain determines the protein's structure and ultimately its function.

What is the smallest functional and structural unit of protein?
The smallest structural unit of a protein is the amino acid. The smallest functional unit of a protein is a little ambiguous, because some might consider the amino acid to be functional (after all, some can function as neurotransmitters). Or, some might consider the peptide (di, tri, etc) to be a functional unit. One could argue what exactly is the smallest functional unit of a protein.
What is the difference between domain and motifs in protein structure?
The main difference is a domain can remain stable independently without the rest of the protein but motif can't be. The Domains can sustain it functional ability when separated from the parental protein polypeptide.
Which level of protein structure has four subunit peptides?
Quaternary structure of proteins consists of multiple polypeptide subunits coming together to form a functional protein complex. If a protein has four subunit peptides, it exhibits quaternary structure.
What is it called when you heat a protein and ruin its structure?
It is called protein denaturation when heat causes the protein's structure to unfold and lose its functional shape. This can result in the loss of the protein's biological activity or ability to perform its intended function.
A protein folded into a globular shape in having only one polypeptide chain has what structure?
The protein would have a tertiary structure. This structure results from the unique folding of the single polypeptide chain into a 3D shape, giving the protein its functional conformation.
