Most complex Molecule?

protein>?

I thought that hemoglobin had a weight of 60 000g / mol.
Thats pretty impressive.

The most common hemoglobin found in humans
has the chemical formula
CA2952H4664N812O832S8Fe4
so that would probably not meet your
criteria of having maximum no of
elements.

I would imagine it to be something
within the field of biochemistry tho...

Ok So haemoglobin is in... protiens are considerable too. any more?

[Cytosolic chaperonin CCT: the most complex molecular chaperone?]

There is more to a complex molecule than just how many elements it contains. You must also think about stereochemistry. Something like vancomycin is INCREDIBLY complex because of the amount of stereocenters it contains. If one of those stereocenters is off, the compound may be inactive.

Carbon has the ability to form amazingly large molecules. As for complex, I'm not sure--but in my opinion one of the most complex azetropes of carbon is diamond. Made up of only carbon atoms, the diamond molecule is crosslinked beautifully geometrically--so much so that a perfect diamonds is essentially a gigantic molecule.

As for complexity--every protein is made up of amino acids, consequently the ultimate in amino acid/protein chains would be near, if not the, most complex biological molecule. One could argue that DNA/RNA with molecular weights in the tens of millions would achieve ultra complexity.
