Need help with my absurd-chemicals-name-collection
i have at times come across some hilariously complex names for chemicals, i believe it might be an oncoming hobby for me, i have thus far collected
these:
3,4-dihydroxy-9,10-seco-androst-1,3,5(10)-triene-9,17-dione,
1,2,3,5,6,7-Hexahydroxyanthracene-9,10-dione
p,p-dibromo-diphenyl-1,1,1-trichloro-ethane
1,3,5-triethyl-1,3,5-triaza-2,4,6-trimethylcyclohexane
2-(2-methoxypropoxy)-2-(2-methoxypropoxy)propanol
7-Chloro-1-methyl-5-phenyl-1,3-dihydro-2H-1,4-benzodiazepin-2-one-diazepam
(2Z)-7-Chloro-N-methyl-5-phenyl-1,3-dihydro-2H-1,4-benzodiazepin-2-imine 4-oxide
Ethyl 4-(8-chloro-5,6-dihydro-11H-benzo[5,6]cyclohepta[1,2-b]pyridin-11-ylidene)-1-piperidinecarboxylate
but i really wanna see how long and absurd these IUPAC names can end up as, i would be gracious for input on this.

"The chemical name for remdesivir is 2-Ethylbutyl (2S)-2-{[(S)-{[(2R,3S,4R,5R)-5-(4-

I have always been wondering what the full name for aconitan would be

The IUPAC names for proteins name every amino acid residue that make them up. So titin, the largest protein ever characterized, with over 30,000
residues, has an IUPAC name that is over 180,000 letters long:

just under 190k it seems, tempted to recite it all just as a challenge
now, methionyl, on its own is "CH3S(CH2)2CH(NH2)CO"
i guess when aminoacids are involved its a different kind of game, stretching into infinity, but technically it is the same - despite they lack the
numbers that i adore so much

You could go completely overboard and start naming the human chromosome 1, which is 249 million base pairs large. There are most likely larger
chromosomes known though. One DNA strand is composed of two molecules, although I think the number 249 million has to be divided by two as well as a
chromosome exists of two double stranded helixes.

Plain sugar (C12H22O11) has the following name:
(2R,3R,4S,5S,6R)-2-[(2S,3S,4S,5R)-3,4-dihydroxy-2,5-bis(hydroxymethyl)oxolan-2-yl]oxy-6-(hydroxymethyl)oxane-3,4,5-triol

Apperantly to get the stereochemistry of something simple like mannitol right you have to name the six carbon chain twice:
(2R,3R,4R,5R)-Hexane-1,2,3,4,5,6-hexol
Edit, nevermind, brainfart. Of course they don't mention the six carbons twice. I didn't have enough coffee

Wheat chromosome 3B is 0.83 gigbases long (for comparison, the entire human genome is about 3.1 gigabases). I've seen claims that the tulip has chromosomes large enough to contain the entire human genome but so far as I can tell the sequence hasn't been published yet.
If the forward and reverse strands were joined at a telomere, you could double the molecule length (and hence its name). I don't know offhand of a way
to do this but it's plausible one exists; the two ends are right there in close proximity.

Tsjerk: [5-amino-2-[[[5-amino-2-(hydroxymethyl)oxolan-3-yl]oxy-hydroxyphosphoryl]oxymethyl]oxolan-3-yl] (5-amino-3-hydroxyoxolan-2-yl)methyl hydrogen
phosphate
seems good enough to me for now 
woelen: the fact that its an everyday item just makes it extra fun to me, maybe its about time we upgrade the DHMO ban to a
(2R,3R,4S,5S,6R)-2-[(2S,3S,4S,5R)-3,4-dihydroxy-2,5-bis(hydroxymethyl)oxolan-2-yl]oxy-6-(hydroxymethyl)oxane-3,4,5-triol-ban
im thinking the one texium posted could maybe be the chemistry version of extending pi, they have these little competitions where they write as many
characters after pi as they can manage, but its based on some logical formula rather than just pure memory
if human genome is 3.1 billion bases long, then the 190k long protein is quite small in comparison

I wondered what titin did. Apparently it gives elasticity to muscle fibers.
According to Wiki: Titin is the third most abundant protein in muscle (after myosin and actin), and an adult human contains approximately 0.5 kg of
titin.[13] With its length of ~27,000 to ~35,000 amino acids (depending on the splice isoform), titin is the largest known protein.[14] Furthermore,
the gene for titin contains the largest number of exons (363) discovered in any single gene,[15] as well as the longest single exon (17,106 bp).
Thats crazy its coded in 363 parts with 363(-1 probably) spaces (introns). The parts have to be linked or the protein bits have to be linked to make
the whole protein. Evolution seems very inefficient.
I am wg48 but not on my usual pc hence the temp handle.
Thank goodness for Fleming and the fungi.

Inefficient? Flexible I would call it. There are 13 known isoforms, which can all be made from the same gene. Parts aren't linked, the introns are
removed at the RNA level when constructing the mRNA

Long names are one thing but there are plenty of fun names in chemistry. alkoxide, bullvalene, and the ever-enduring arsole are among my favorites.

If anything, titin is unusally efficient in its use of genomic real estate. Here it is in the UCSC browser; there is relatively little space that isn't used in one transcript isoform or another.
By contrast, a little down the chromosome arm there's a more run of the mill zinc finger protein. It's transcript is only ~2.5kb to titin's ~100kb,
but it occupies a larger stretch of DNA. Nearly all of the gene locus is intron!

Well, evolution is usually very simple; either there is a reason for something to be the way it is or it really doesn't matter that much.
