hmm. 3 more folding engines. I’ve covered one: etrenafold. I heard it’s pretty weird. I know it’s pretty weird. but no one ever talks about contrafold. I think it’s pretty much the same as eternafold, but who knows? let’s try the boosts!
The hook boost
Now, this is the contrafold hook with the GC as closing pair.
-0.29 kcal. very interesting. let’s put a C on the hook.
-0.51. kcal. not as much as eternafold. let’s do a G.
let’s test with U.
The 1-1 boost
As we all know, in eternafold, we put a U on either side of the 1-1.
but, we must know what the energy is with NO boosts.
(it made the loop 1.41 kcal)
The 2-2 loopWe like 2-2 loops. they are so easy to boost. just put a G and another G and two Us. bam! -4.1 kcal. but that's in Vienna. not contrafold. so let's find the contrafold boost for the 2-2. we need to know the energy of the 2-2 with no boosts.
1.44 kcal! now let’s do the GAGA boost, just like the eternafold.
-0.09 kcal! now let’s do all blue.
very high energy. not good. let’s do all red.
(it wasn’t good at all)
The triloop boostwe all know what a triloop is. it's this loop.
(the one on the right, not the left)
to boost it, put a G on the left of the closing pair, as shown on this figure
That ends, my tutorial for contrafold, more loops coming soon to this post, and more basics coming, tell me what to put on here in the comments, and please give it a heart <3 thanks!
Also, please tell me which boost you liked the most! thanks!
- 2-2 loop
- 1-1 loop
