Peptide Beer Cozy!

Based on the amino acid charts that I have designed, I decided to take them to the next level and make a peptide pattern. Here I incorporated it into a beer cozy.

Materials Required
  • worsted weight yarn - I used Wool of the Andes from KnitPicks: Lake Ice Heather (MC), Winter Night (Nitrogens), Hollyberry (Oxygens), and Black (bonds).
  • size 3 double pointed needles (I like a tight gauge on my cozies)
  • A beer bottle to check the desired height







Pattern
  • Cast on 45 sts in the main color (this will be the top of the cozy)
  • k2, p1 *repeat for three rows
  • Start the chart, working from the bottom up, right to left. (note that the first charted row is all in the main color) (Please notice the update. I have rotated the chart so you can make the cozy as shown in the picture versus knitting the mirror image. I managed to invert it correctly in my head as I made the cozy myself.)
  • (starting the decreases for the bottom - you may want to make the decreases faster or slower depending on your gauge.) K5, K2tog * repeat 6 times, K3 (39 sts)
  • k1 round even
  • K1 K2 tog (26 sts)
  • K1 round even
  • K2 tog across (13 sts)
  • K2 tog across, K1 (7 sts)
  • pull remaining stitches together. weave in loose ends.


You could incorporate any of the amino acid charts that I have published previously to create your own peptide chart. This particular amino acid sequence (HNAVS, aka His-Asn-Ala-Val-Ser) has no meaning other than it would fit on a beer cozy and I though these residues would be pretty. (Histidine happens to be my favorite amino acid, and I do have some affection for asparagines as well from my research.)

I did a BLAST (i.e. search all know protein sequences for this stretch of amino acids) this peptide sequence, the first non-hypothetical protein hit is a isopenicillin N epimerase, which is involved in penicillin biosynthesis. (For those of you who know what my research is about, this will be really funny!) Now, since there

I expect that this will be a hit around the lab!

  2. Crazy cool cryptographic cozy!

  3. Wow- what a cool idea. It would be fun to design a cozy with a molecule thay is found in beer- and of course I'm an idiot in this department- but maybe some sort of carbohydrate, I know they're huge molecules, at least potentiallly. Or a sugar? Very cool!

  4. Hmm, how do you get your pattern into such a nice graph? BTW, this is really clever!

  5. I think you should do a salty dog beer cozy. Thats citric acid and ethanol.

  6. I used Microsoft Excel to make the chart. Maybe I'll have to make a post on that sometime!

  7. hey i dont know how to do this can someone make a maroon rasta colored one with a necklace half inch strap that woulb f*ckin sweet

  8. So making a beer cozy necklace? I would be concerned with spills, but you could definitely add a knit (or even braided) strap to the cozy....

  9. This is such a neat idea. I took a beginning human physiology course and this just became so relavant!! haha I don't know how to knit yet (just getting started), but I think this will be one of my first projects just for the fun of it! How about a poly-peptide chain?

  10. Well TECHNICALLY you could consider a pentapeptide a polypeptide ;) I'm not sure what I would make with a longer peptide chain, I would love to use the amino acids to spell relevant things... Maybe a scarf someday?
