Can you please tell me what is in this picture?

Greetings, good people, I am in need of HELP! My girl has a tattoo and won't tell me what it is, so far i have narrowed it down to aminoacids, nitrocyclopenthane, I guess... I have absolutely no knowledge of chemistry and any kind of help is welcome. I was told by a friend that the sequence is SEEPPISLELQ but I don't know if that is correct. The link bellow is the pic. I apologize if this is not the right place to post such questions, but I am out of ideas. Thank you all in advance and best of luck in all your future endeavours.



Best regards,
Milan

It's definitely a short protein of some sort; there are common amino acids connected by peptide bonds. Oxytocin is a popular oligopeptide tattoo, but that is usually cyclic with a disulfide linkage, and this one has no sulfurous residues.

I haven't checked reside for residue, but the two prolines (PP) preceded by two glutamic acids (EE)
lend the stated sequence credibility.

I used NCBI BLAST to do a protein-protein search on this sequence and got multiple hits to part of corticoliberin, aka corticotropin-releasing hormone (although they all disagree slightly on the sequence: SEEPPISLEL vs. SEEPPISLDL )

Does the lady use drugs, particularly alcohol or cocaine?

Has she had a child?

Is she highly stressed/suffers from PMS?

(On a quick scan of Wikipedia's list of related functions)

It's funny because there's actually some mistakes on it. If she's going to bother having a geeky tattoo at the very least she should be geeky enough to get it right. :) That's my philosophy anyway. I'm referring to a C=OH bond. There's also a "2" missing from the H of the amide at the right.

I'm going to go out on a limb here here and say she's tattooed "LOVE" on her arm.
