"Identify the molecule" league #14. Prize: knowledge + 100 STEM + 200 TMN
**This contest is an attempt to promote scientific knowledge among community in a fun and interesting way with the help of molecules.**
Some people like to travel around the world and tell others stories about what happens outside of our organisms/cells in other countries.
And with “Identify the molecule” contest you can try to travel inside our own organism/cells and cells of the organisms around us.

***For more information about this contest read ["Identify the molecule" contest. Upgrade (the league, additional bonuses and more)](https://steemit.com/science/@alexbiojs/identify-the-molecule-contest-upgrade-the-league-additional-bonuses-and-more) post.***

### Prizes/bonuses:
**The prize here is**

**1. knowledge**

> facts, information, and skills acquired through experience or education; the theoretical or practical understanding of a subject
[Oxford Dictionary of English, 3rd Edition, Oxford University Press, 2010]

That understanding of our own organism and organisms around us is the real prize in the case of this contest. No matter what happens (whether or not you get 100 STEM), you can win (can acquire the knowledge by investigating different sources of information, remembering and using it to your advantage in the future).

**2. 100 STEM**
> STEMGeeks is a community focused on STEM topics rewarding engagement with STEM tokens. STEMGeeks is powered by the Steem blockchain with it's own distribution model for STEM tokens in addition to the potential STEEM tokens.
STEM stands for Science, Technology, Engineering, Math and includes a wide range of science and technology topics.
[[source](https://stemgeeks.net/stem/@stemgeeks/announced-stemgeeks-a-new-steem-engine-tribe)]

**3. 200 TMN**

Aside from STEM I’d like to add [TMN tokens](https://coinmarketcap.com/currencies/translateme-network-token/).
For the uninitiated, TMN is the token of [TranslateMe project](https://translateme.network/) (it’s about combining blockchain technology (NEO in this case) with translation industry).
The reason I’m going to add this token for the prize pool of this contest is not only because I have them, but because this contest is quite scientific, and TranslateMe project might help to solve **the “lost” science problem**.
For more on this you can read my post regarding TranslateMe [(TranslateMe (or Decentralization meets Translation industry). Part 2. The “missing puzzle piece” of scientific ecosystem. General overview)](https://beta.sapien.network/t/science/@alexbiojs/translateme-or-decentralizatio-seocRSKf) (and other posts of that series).

**For more information on crypto-bonuses for this league, please refer to ["Identify the molecule" contest. Upgrade (the league, additional bonuses and more)](https://steemit.com/science/@alexbiojs/identify-the-molecule-contest-upgrade-the-league-additional-bonuses-and-more) post.**

**Consider these tokens as a bonus.**

Images and text are **the clues** for you to guess a riddle (the name of the molecule in this case).

### Note that
**a)** even though this contest is called “Identify the molecule”, 
-> molecule (singular)
sometimes it’s not just a molecule which is responsible for a specific function, but rather a **complex of molecules**.
**Example:**
cytochrome c oxidase (Complex IV)
> is a large transmembrane protein complex… It is the last enzyme in the respiratory electron transport chain of cells located in the membrane.
[source](https://en.wikipedia.org/wiki/Cytochrome_c_oxidase)

**b)** some molecules/complexes have different names. For example, other names for cytochrome c oxidase (example above) are 
> Complex IV (mitochondrial electron transport).
Cytochrome a3.
Cytochrome aa3.
Cytochrome oxidase.
Warburg's respiratory enzyme.
[source](https://enzyme.expasy.org/EC/1.9.3.1)

Any of those names would be a valid entry.

**c)** Some almost identical molecules are grouped into classes / groups / families. 
**Example:**
[Helicases](https://en.wikipedia.org/wiki/Helicase) are divided into 6 groups. RecD and Dda molecules belong to helicases group (Superfamily 1 (SF1)). In this case you would need to guess only the name of the group –> Helicase/ Helicases.


**d)** Some proteins can have different forms – [isoforms](https://en.wikipedia.org/wiki/Protein_isoform).
**Example:**
[There’re trypsin 1 and trypsin 2](https://en.wikipedia.org/wiki/Trypsin). In this case you would need to guess only the general name – [trypsin](https://en.wikipedia.org/wiki/Trypsin).

---

### Important
In order to get TMN, you’ll need to have NEO-wallet and provide me your public NEO-address.
If you don’t have it yet, don’t worry, I published [a post on how/where to get it (O3 wallet)](https://steemit.com/neo/@alexbiojs/o3-your-gateway-to-the-smart-economy-of-neo-and-ontology-introduction-part-1-o3-wallet-a-creating-a-new-wallet).
Note that NEO-addresses provided by exchanges will not work in this case (+ it's safer NOT to keep your funds on exchanges). It's highly recommended to get O3 wallet.

***If there’re no winners on any stage, the prize will be distributed equally among all users who provided any guesses for molecules.***

### Riddle

<center>![riddle_14_1.png](https://cdn.steemitimages.com/DQmPzSKkxgaF1XWFdtYXc9bC8giV9e35xcEJmfjP6byFbrt/riddle_14_1.png)</center>
<center>(Cartoon representation. The image was created by me with the help of [PyMol](https://github.com/schrodinger/pymol-open-source) - open source tool for molecular visualization/exploration. PDB-file was obtained from [PDB](https://pdb101.rcsb.org/))</center>

The molecule could serve as a possible explanation (well, quite exaggerated, actually) for the **disproportions** we can see in the [Gulliver's Travels](https://en.wikipedia.org/wiki/Gulliver%27s_Travels) film (initially written by the Irish writer [Jonathan Swift](https://en.wikipedia.org/wiki/Jonathan_Swift))

![Riddle_14_5.png](https://cdn.steemitimages.com/DQmV7Etaq8diqt3k6NtV2NbEaxQ75NG1HcYt5rBdPtfU1PD/Riddle_14_5.png)

(screenshot was taken from [Gulliver's Travels - Classic Films](https://www.youtube.com/watch?v=xwZK17qXt9o))

(screenshot was taken from [Gulliver's Travels - Classic Films](https://www.youtube.com/watch?v=xwZK17qXt9o))

The molecule has [anabolic effects](https://en.wikipedia.org/wiki/Anabolism) on the tissues in our body.

### "Edited"

Here’s the data showing where (in what human normal tissues) the gene of this molecule is [expressed](https://en.wikipedia.org/wiki/Gene_expression) the most:

![riddle_14_4.png](https://cdn.steemitimages.com/DQmVe94zMPTrDc8sN4vTtBswHnBJiF6yKSWnW4DopAXH1dA/riddle_14_4.png)

(in other words, those are the places where the molecule is present in abundance)

The data were obtained with the help of [Metabolic gEne RApid Visualizer](http://merav.wi.mit.edu/SearchByGenes.html)


### "Edited"

[Lionel Messi](https://en.wikipedia.org/wiki/Lionel_Messi) has problems with this hormone.

### Rules

This contest lasts for 6 days. 

Leave your guess (1 guess only) in the comments section of the post.

Don’t edit your comment and don’t provide any evidence that your answer is correct.

I’ll provide the answer in the comments section of the next post on the 7th day of the week’s stage.

The first user with correct answer is the winner.

Some of the clues have already been provided in the post.

Additional clues will be given in 2 days (on Monday, February 10, 2019, 20:00 ± 2 minutes UTC) (I’ll update this post).

And the rest of the clues will be provided in 2 more days (on Wednesday, February 12, 2019, 20:00 ± 2 minutes UTC) (I’ll update this post).

The reason is that some people might need less information to make conclusions that the others.

Additional clues will be added at the end of the "Riddle" section before the "Rules" section with "Edited" label.

The winner will be announced on Friday, February 14, 2019, 20:00 ± 2 minutes UTC in the comments section of the next post. Plus I’ll publish a detailed review of the riddle **after a while**.

I’ll transfer the tokens (STEM + TMN) (if the winner provides me his/her NEO-address) to the winner on that day (February 14) and add the transaction ID in the comments section.

**I’m planning to run this contest every week.**
**So, you should expect to see the 2nd week’s riddle for January on Saturday, February 15, 2019, 20:00 ± 2 minutes UTC.**


### References

I’ll add all the references for this post later, because most of them contain the name of the molecule.
That would be a spoiler.
I’ll add them **after a while**.


### Important

This contest is the work in progress.
A lot can be changed in the future.
**Any recommendations/suggestions are very welcome.**
**If you have any questions, feel free to ask them in the comments section.**

<b>Growth hormone</b>
Growth hormone (GH) or somatotropin, also known as human growth hormone (hGH or HGH) in its human form, is a peptide hormone that stimulates growth, cell reproduction, and cell regeneration in humans and other animals. It is thus important in human development. GH also stimulates production of IGF-1 and increases the concentration of glucose and free fatty acids.  It is a type of mitogen which is specific only to the receptors on certain types of cells.
