The primary structure is simply a long chain of peptides (polypeptide chain). The peptide monomers are like letters in a long, long word (the polypeptide). The word, a product of the primary structure and the peptide bonding sequence means something - whether it be, "I'm a transport protein." or "I'm an enzyme!". So, the primary structure definitely dictates the function of a protein by the sequence of amino acids it has. The primary structure's sequence of amino acids also dictates how the polypeptide will form (its structure). The R-group on the amino acids, which varies, will cause an amino acid to be positive, negative, polar, or nonpolar. This will cause the peptide chain, after these amino acids have been put together through dehydration reactions, to attract/form bonds with each other differently, leading to specific structures based off of the primary structure of a protein. These bonds vary between hydrophobic interactions, van der Waals attractions, hydrogen bonds, disulfide bridges, and a couple of other bonds. These new bonds and formations result in the secondary and tertiary levels of structure

What are the roles of N-linked and O-linked glycosylation in protein structure and function?
N-linked glycosylation helps with protein folding, stability, and recognition of the protein by other molecules. O-linked glycosylation can affect protein function by regulating protein activity, localization, and interactions with other molecules. Both types of glycosylation play important roles in modifying protein structure and function.
Does amino acids affect protein functions?
The sequence of amino acids affects protein function. The three-dimensional structure of a protein determines its function. The three-dimensional structure of a protein is determined by the sequence of its amino acids.
Why does the structure of a protein or enzyme determine its function?
Yes.
How does mitochondrion structure affect its function?

How does a mutation change the events at the ribosome?
Mutations can alter the sequence of amino acids in a protein, which can affect the protein's structure and function. This can impact the protein's ability to interact with the ribosome and other molecules involved in protein synthesis, potentially leading to changes in the efficiency or accuracy of protein production.
Why is the structure of a protein important for its function?
The structure of a protein is important for its function because the specific arrangement of amino acids determines how the protein interacts with other molecules. This structure allows the protein to carry out its specific biological roles, such as catalyzing chemical reactions or serving as structural components in cells and tissues. Any changes in the protein's structure can affect its function and potentially lead to diseases or disorders.
A protein's function is dependent on its?
structure, which is determined by its amino acid sequence. The shape of a protein allows it to interact with other molecules in the cell and carry out specific functions. Changes in the protein's structure can affect its function and lead to disease or dysfunction.
What is the significance of the three-dimensional structure of a protein in relation to its function and interactions within a cell?
The three-dimensional structure of a protein is crucial for its function and interactions within a cell. This structure determines how the protein can bind to other molecules, such as enzymes or receptors, and carry out specific tasks. Changes in the protein's structure can affect its function and ability to interact with other molecules, leading to potential disruptions in cellular processes.
How do changes in DNA affect the production and function of proteins?
Changes in DNA can affect the production and function of proteins by altering the sequence of amino acids in the protein. This can lead to changes in the structure and function of the protein, which can impact various cellular processes and functions in the body.
What is the protein denaturation temperature and how does it affect the structure and function of proteins?
Protein denaturation temperature is the temperature at which a protein loses its natural shape and function. When proteins are exposed to high temperatures, their structure unfolds and they lose their ability to perform their biological functions. This can lead to a loss of enzyme activity and disrupt the protein's overall function in the body.
What are the roles of N-linked and O-linked glycosylation in protein structure and function?
N-linked glycosylation helps with protein folding, stability, and recognition of the protein by other molecules. O-linked glycosylation can affect protein function by regulating protein activity, localization, and interactions with other molecules. Both types of glycosylation play important roles in modifying protein 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.
Does amino acids affect protein functions?
The sequence of amino acids affects protein function. The three-dimensional structure of a protein determines its function. The three-dimensional structure of a protein is determined by the sequence of its amino acids.
What is the three-letter code for aspartic acid and how does it contribute to protein structure and function?
The three-letter code for aspartic acid is Asp. Aspartic acid contributes to protein structure and function by participating in the formation of hydrogen bonds and electrostatic interactions within the protein molecule. It also plays a role in maintaining the overall charge balance of the protein, which can affect its stability and function.
How does the formation of an oxidized disulfide bond impact the structure and function of proteins?
The formation of an oxidized disulfide bond can impact the structure and function of proteins by stabilizing the protein's three-dimensional shape. This bond helps maintain the protein's structure and can affect its stability, activity, and interactions with other molecules.
How does deletion mutation affect the structure and function of proteins?
Deletion mutations can cause a shift in the reading frame of a gene, leading to the loss of one or more amino acids in the protein sequence. This can result in a non-functional or altered protein structure, affecting its function.
What is the significance of the protein terminus in the process of protein folding and function?
The protein terminus plays a crucial role in protein folding and function by influencing the structure and stability of the protein. It can affect how the protein interacts with other molecules and determines its overall shape and function. The terminus also helps in directing the folding process and can impact the protein's activity and localization within the cell.
