Why is the primary structure of a protein important in order to carry out its activity especially if this protein has a catalytic activity?
The primary structure of a protein is the sequence of amino acids in each of its chains. (Some proteins have more than one chain.)This sequence determines how each chain coils and turns (the secondary structure), and in turn how the whole molecule folds (the tertiary structure). The correct primary structure is essential for the chain to acquire the correct three-dimensional (3-D) shape.Some amino acids have negative charges on them at physiological pH; some positive. This will influence how different sections of a chain attract and repel one another, and in turn this affects the final shape. Also, one of the amino acids can form sulfur-sulfur cross-links between different parts of the chain. Hydrogen bonding can hold different sections of a chain in position, too, and this will only occur between certain amino acids.If the protein is an enzyme, it has one or more active sites. Each of these has a shape that is complementary to part of the relevant substrate. So the enzyme must have the correct shape if it is to exhibit catalytic activity.
Is a movie a primary source?
No, bibliographic refers to books.
What is the primary government structure in New Zealand?
New Zealand is a parliamentary democracy.
Is protein larger in size compared to a polypeptide?
A protein is a polypeptide.
What is the relationship between a cell's shape and its function?
The shape of the cell determines its function function because take for example skin cells. They are flat and protect the cell like it's function. Addition: Red blood cells have an indent on which they carry and transport oxygen molecules.
Which level of protein structure is unaffected when a protein is denatured?
The primary structure
What is primary structure of a protein and what causes it?
Primary structure of the protein is simply its amino acid sequence. It is the sequence in which amino acids are added during protein synthesis.
Is the structure of protein primary?
The primary structure of proteins is simply a peptide (chain of amino acids).
Differentiate the four types of protein structure?
There are four types of protein structure. These include primary structure, secondary structure, tertiary structure, and quaternary structure. Primary structure is the amino acid sequence. Secondary structure is the shape of the molecule. Tertiary structure is the interaction between groups. Quaternary structure is the interactions between protein subunits.
Of the four protein structureswhich level is lowest level of a protein structure?
the primary structure is the lowest level
What is the level of protein structure is the amino acid sequence of the protein?
Quaternary tertiary secondary primary is the sequence.
What is distinctive about primary vs secondary protein structure?
The primary structure of a protein is just an amino acid string; a polypeptide. The secondary structure of a protein is the hydrogen bonding of the side chains that form the polypeptide chain into alpha helices and beta sheets.
Which level of protein structure may be stabilized by covalent bonds?
Primary, tertiary and quaternary levels of protein structure.
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)
The sequence of amino acids joined together refers to the?
Peptide sequence or amino acid sequence is the order in which amino acid residues, connected by peptide bonds, lie in the chain in peptides and proteins. The sequence is generally reported from the N-terminal end containing free amino group to the C-terminal end containing free carboxyl group. Peptide sequence is often called protein sequence if it represents the primary structure of a protein.
What are the subgroups of protein?
There are four distinct levels of protein structure. The main two are primary, amino acid, secondary structure, and quaternary structure.
What is the primairy structure of a protein?
Primary - the sequence of amino acids that make up a protein
