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)
Why protein is called primary structure?
Proteins *have* primary, secondary, tertiary, and quarternary structures. The primary structure is simply the chain of amino acids without any other structure. Secondary structure results from folding of the chain to form rudimentary structures such as alpha helices, beta sheets and turns. Tertiary structure results from the further folding of the protein with secondary structures into different 3D shapes by interactions between different parts of the secondary structure. Quarternary structure results from different proteins with tertiary structures coming together to form a protein complex.
How can you distinguish between primary secondary tertiary and quaternary structures of proteins and can you give an example of each?
Primary structure of proteins refers to the exact sequence of the amino acids in the polypeptide chain. Secondary structure refers to the shape acquired by the backbone of the polypeptide chain when hydrogen bonds form between the carboxylic group of one amino acid and the amide group of another amino acid. there are two shapes in secondary structured proteins: Alpha Helix and Beta-pleated sheet tertiary structure refers to the shape taken up by the polypeptide chain as a result of bonds formed between the R-groups of the amino acids. three types of bonding may exist: Hydrgen bond, ionic bond and /or disulphide bonds.
What are the different levels of protein structure and how are they determined?
Primary: Specific Sequence of amino acids specified by the Gene; Secondary: Portions of proteins begin to coil and fold into unique 3D conformations; Tertiary: Formed by interactions between side chains of various amino acids; Quaternary: Incorporate multiple polypeptide "sub-units."

Define primary structure and describe how it may be deduced in the laboratory?
The primary structure is the formation of the amino acid sequence within a protein. It can be deduced in a laboratory by hydrolyzing the protein into small peptide chains, dehydrolyzing the protein into small peptide chains, determining their amino acid sequences, and then overlapping the sequences of small fragments created with different agents to reconstruct the whole polypeptide.
The primary structure of a folded protein is?
The simple polypeptide chain.
The three-dimensional shape of a polypeptide is associated with its?
primary structure
What is the primary level of the protein structure?
Just the polypeptide chain of amino acids.
What is the primary structure of DNA?
The sequence of nitrogenous bases forms the primary structure of the molecule, analagous to the sequence of amino acids in a polypeptide.
What is the linear sequence of amino acids in a polypeptide chain is called?
primary structure
What maintains the primary polypeptide structure?
Peptide bonds between the individual amino acids.
What is protein primary structure?
it's a genetically coded sequence of amino acids in a polypeptide chain
Is a quaternary structure a polypeptide sequence of amino acids?
No, the polypeptide sequence of amino acids is the primary structure of a protein. The quaternary structure of the protein is the non-covalent interactions (hydrophobic binding, van der wals forces etc..) between subunits/domains of a protein.
What characteristic of amino acids determine the primary structure of proteins - Acid-base properties - Side chain composition - Hydrogen bonding properties - Sequence in polypeptide chains?
If you are asking which of the four following answers determines the primary structure of proteins, the answer would be d) sequence of polypeptide chains. After translation and transcription, the order of the bases codes for the proteins that are made. Hope that helps!
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 is the linear chain of amino acids in a protein?
The monomers in a polypeptide are the amino acids. The sequence of amino acids in a polypeptide (or protein) is called the primary structure. It is the primary structure of proteins which is coded for by the DNA in the genes: the sequence of bases in the DNA is a code for the sequence of amino acids in a protein (or polypeptide).

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)
