The 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.
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.
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.
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.
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.
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.

The structure of the hemoglobin in a molecule is the quaternary structure.
The most complex level of protein structure is the quaternary structure. This level describes the arrangement of multiple protein subunits to form a functional protein complex. Quaternary structure is essential for the overall function and stability of many proteins.
The microscopic, functional unit of the kidney and the site of urine-production is the Nephron.
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.
This unit is called the nephron.nephronnephronsglomerulus/ glomeruli and associated nephronsnephrons
A protein complex is formed when two or more proteins interact and come together to carry out a specific biological function. These proteins can physically associate with each other to form a stable complex through non-covalent interactions. The complex often has a unique structure and function different from the individual proteins that comprise it.
The structural and functional unit of the nervous system is the neuron cell.
The primary protein structure is dependent on the specific sequence of amino acids that make up the protein's polypeptide chain. This sequence is determined by the genetic code encoded in the DNA of the organism. Any changes or mutations in this sequence can alter the protein's structure and function.
