Haha wait are you in Amherst College biochemistry? What are the odds that 682 showed up on another college's problem set?
Use 110 g/mol per amino acid (already corrected for the loss of water in amino acid condensation during formation of the protein) and multiply.

What are the polymers of protein?
The polymers of protein are polypeptide or enzymes.
What determines the primary function of a protein?
The way that a polypeptide folds to form the protein determines the proteins function.
What term is used to describe the arrangement of different polypeptide chains in a protein?
A Quaternary Structure
A long chain of amino acids?
polypeptides - The Dude That is Friends with THE DUDE
Are proteins large polypeptides?
As a matter of fact, yes. However the term polypeptide is a generic name given to a sequence of amino acids. This terminology varies among scientific researchers. In general terms, a peptide is the conjunction of two or more amino acids and up to 20 to 40 amino acid residues. Therefore, we have dipeptides (two amino acid residues linked by a peptide bond), tripeptides (three amino acids), oligopeptides (from 4 up to 20 or 40 amino acids) and polypeptides. In the particular case of polypeptides is important to mention that a polypeptide is a linear polymer formed by a sequence of amino acids linked "head to tail" by peptide bonds rather than forming branches chains. The range of lenght of polypeptides goes from about 40 to more than 4000 amino acid residues, that is, from an average of 4 to over 440 kD. In general terms, when a polypeptide is too long is called protein.
A polypeptide can best be described as?
Short sequence of amino acids. Insulin is a polypeptide of about 53 [amino-acid] residues; it is like Pluto - is it a protein or not?
Is protein larger in size compared to a polypeptide?
A protein is a polypeptide.
What is the correct order smallest to largest protein - amino acid - polypeptide?
Amino acids---->peptide---->polypeptide--->protein.

What are the polymers of a protein?
Polypeptide
Is a protein a polypeptide?
A polypeptide chain is made up amino acids that form from a peptide bond. The polypeptide chain makes up a protein; therefore, the type of protein is contingent on the number of chains present.
Is polypeptide chain a protein?
A polypeptide chain is made up amino acids that form from a peptide bond. The polypeptide chain makes up a protein; therefore, the type of protein is contingent on the number of chains present.
Are immunoglobulins carbohydrates?
No, immunoglobuline are glycoproteins, they are proteins that bind on the surface of polypeptide chains carbohydrate residues. This means that there is a carbohydrate component in immunoblobulins, but their dominant behavior is that of a protein, even if their sugar part is important in determining their behavior.
What kind of macromolecule is polypeptide?
protein
Treatment of RNase with 8M urea but without adding mercaptoethanol would?
Urea itself will only break non-covalent bonds, breaking any protein into its basic subunits, polypeptide chains of amino acids. Without mercaptoethanol this would be the end result, and from this you could deduce whether the protein was a dimer, tetramer, etc. Mercaptoethanol is an oxidizing agent which is used to oxidize the disulfide bridge formed between cysteine residues. Oxidation of these sulfur atoms results in the disulfide bridge being broken, further reducing the protein (now polypeptide chains) into its smaller subunits. If successful, all of the collected protein remains should equal the total molecular weight observed in the protein in its entirety.
What chain is sequences of amino acids that is the foundation for the basic structure of a protein?
polypeptide chain
What is a science name for protein?
The other name for protein is hhhjguddf.
