Proteins are composed of amino acids, each of which have their own special properties. The non-polar amino acids would fold into the interior of the protein during protein folding, because they are hydrophobic. A protein consists of a primary structure, which consists of the amino acid chain. The secondary structure is how the amino acids join together into alpha helices and beta pleated chains and form hydrogen bonds. The tertiary structure is when disulphide bridges form, which maintain the protein's 3D shape, and the 3D shape begins to emerge. The quaternary structure is an assortment of several polypeptides, and constitutes the entire protein. The final shape of the protein determines its function.
For example an enzyme carry out catalytic functions are mainly accomplished by it's catalytic core residues(place where substrate binds). when the 3D structure of protein is properly made(folded) then it is active, when a single residue is mutated or any improper folding leads to the enzyme either hyperactive, poorly active or inactive.

What is the relationship between the N to C terminus in protein structure?
The relationship between the N-terminus and C-terminus in protein structure is that they are the two ends of a protein chain. The N-terminus is the starting point of the chain, while the C-terminus is the ending point. These termini play a crucial role in determining the overall structure and function of the protein.
What is the difference between a domain and a motif in the context of protein structure?
In the context of protein structure, a domain is a distinct and independently folded region of a protein that performs a specific function. A motif, on the other hand, is a smaller, recurring structural pattern within a protein that may not have a specific function on its own but contributes to the overall structure and function of the protein.
What is the relationship between a base pair and the corresponding amino acid in the process of protein synthesis?
During protein synthesis, a base pair in DNA codes for a specific amino acid. This relationship is crucial because the sequence of base pairs determines the sequence of amino acids in a protein, ultimately influencing its structure and function.
What is the significance of the beta-branched side chain amino acid in protein structure and function?
The beta-branched side chain amino acid plays a significant role in protein structure and function by influencing the folding and stability of the protein. It can affect the interactions between different parts of the protein and its overall shape, which in turn can impact its function in biological processes.

What is the relationship between cysteine and serine in protein structure and function?
Cysteine and serine are both amino acids that play important roles in protein structure and function. Cysteine is known for forming disulfide bonds, which help stabilize the structure of proteins. Serine, on the other hand, is often involved in enzymatic reactions and phosphorylation events that regulate protein function. Overall, the presence and interactions of cysteine and serine in proteins contribute to their overall structure and function.
What is the significance of the interaction between serine and cysteine in protein structure and function?
The interaction between serine and cysteine in protein structure is significant because it can form disulfide bonds, which help stabilize the protein's three-dimensional structure. This interaction plays a crucial role in maintaining the protein's shape and function.

Give an example of the relationship between structure and function?
One example of the relationship between structure and function is found in enzymes as their function is dependent upon its structure. Enzymes are catalytic proteins that speed up a reaction without being consumed. Their protein structure enables them to recognize their substrates, even among isomers, thus allowing them to catalyze very specific reactions. The interactions between a protein's primary structure, its amino acid sequence, determine its secondary structure of hydrogen bonded alpha and beta pleated sheets. The side chains of the amino acids help determine the next superimposed structure, the tertiary structure and the quaternary structure if the protein has one. A protein's conformation enables it to form an active site whose shape is compatible with that of the substrate. Once the substrate enters the active site, the enzyme's structure is altered as induced fit moves the active site's chemical groups into positions that enhance their ability to catalyze the chemical reaction, thus improving the enzyme's function. An enzyme's structure is so closely correlated to its function that even a slight change in a protein's primary structure can affect its conformation and ability to function. For example, although noncompetitive inhibitors bind to the enzyme away from its active site, they alter the enzyme's conformation so that the active site no longer has the right structure to bind with the substrates, preventing it from functioning correctly.
What is the difference between the N-terminus and C-terminus in a protein structure?
The N-terminus is the starting point of a protein chain, while the C-terminus is the end point. They are important for determining the overall structure and function of the protein.
How is tertiary protein structure dependent on primary protein structure?
The relationship between the primary and tertiary structure of a protein is the both have a sequence of amino acids in a polypeptide chain.orThe sequence of amino acids in a primary structure determines its three-dimensional shape ( secondary and tertiary structure)
What is the significance of the torsion angle in protein structure and function?
The torsion angle in protein structure is important because it determines the orientation of chemical bonds in the protein backbone. This angle affects the overall shape and stability of the protein, which in turn influences its function. By controlling the folding and flexibility of the protein, the torsion angle plays a crucial role in protein structure and function.
How does DNA sequence determine protein function?
The DNA sequence encodes the sequence of amino acids in a protein, which in turn determines the protein's structure and function. The specific sequence of amino acids determines how the protein folds into its three-dimensional structure, which ultimately determines its function in the body. Any changes in the DNA sequence can result in alterations to the protein structure and function, leading to potential health consequences.
