Amino acid = Smallest building block of proteins; 20 of them. In this order.
Amino acid < dipeptide ( two peptides ) < polypeptide (many peptides ) < Protein

Hydrogen bonds between different parts of the polypeptide chain result in which level of protein structure?
Tertiary structure
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.
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 relationship between the linear sequence of codons on mRNA and the linear sequence of amino acids in a polypeptide?
The linear sequence of codons on mRNA determines the linear sequence of amino acids in a polypeptide.
What is polypeptide?
The official definition of a polypeptide is a linear organic polymer consisting of a large number of amino-acid residues bonded together in a chain, forming part of (or the whole of) a protein molecule. (a string of amino acids)
What maintains the primary polypeptide structure?
Peptide bonds between the individual amino acids.
Hydrogen bonds between different parts of the polypeptide chain result in which level of protein structure?
Tertiary structure
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 is the difference between a peptide and a dipeptide?
Forms between two Adjacent Amino AcidsPeptides (from the Greek πεπτίδια, "small digestibles") are short polymers formed from the linking, in a defined order, of α-amino acids. The link between one amino acid residue and the next is known as an amide bond or a peptide bond.A dipeptide is a molecule consisting of two amino acids joined by a single peptide bond.Proteins are polypeptide molecules (or consist of multiple polypeptide subunits). The distinction is that peptides are short and polypeptides/proteins are long.http://en.wikipedia.org/wiki/Peptidehttp://answers.yahoo.com/question/index?qid=20080511213546AAYRfF7
What is the difference between interchain and intrachain hydrogen bonds in the secondary structure of proteins?
IntrAchain H-bonds stabalize bonds between the same polypeptide chain (alpha-helices). IntErchain- H-bonds stablized between different polypeptide chain. (beta- structures)
What is a difference in the structure of proteins and polysaccharides?
Polysaccharides are essentially many carbon sugar "rings" linked together. They are carbohydrates, and our bodies break them down into monosaccharides (single "rings") to gain energy. To provide energy is their main function. In contrast, a peptide bond is formed between two amino acids via dehydration synthesis. Amino acids are the monomers for proteins within the body, who function in part to catalyze reactions and carry out other directions of DNA. Many peptide bonded amino acids = a polypeptide. The most basic difference would be that polypeptides are proteins, where as polysaccharides are carbohydrates.
Differentiate between secondary and tertiary structure by describing the parts of the polypeptide chain that participates in the bonds that hold together each level of structure?
Secondary tertiary is the R groups interactions that are ionic. The polypeptide chain also has disulfide bond, and hydrophobic interactions.
Which structure in the circulatory system is known to be the smallest kind of blood vessel?
Capillaries, having diameters between about 0.0005 to about 0.008 inches, are the smallest blood vessels.
What are the four stages of protein structures?
The four levels of protein structure are differentiated from each other by the complexity of their polypeptide chain. Proteins are constructed from 20 amino acids. The levels are the hydrogen atom, a Carboxyl group, an amino group and a variable or "R" group. They have a primary structure, the order in which the amino acids are linked to form a protein. Secondary structure , coiling and folding of the polypeptide chain. Tertiary structure, is a 3-D structure of a protein chain. Quaternary is the structure of a protein macro molecule formed by interactions between several polypeptide chains..
The structure of a protein that involves the interaction between two distinct polypeptide chains is?
Protein is made up of amino acids and these acids have peptide bonds between them. As there are different numbers of amino acids in each type of protein, they have different number peptide bonds. Mostly all proteins are polypeptides.
What molecules aid in the folding of a polypeptide chain into its secondary or tertiary structure?
I think it should be bi sulfide bond between two cysteine amine acids witch contains sulfur.(Citation needed. )
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.
