ALMEILAQAARA
Almost all residues come from AMELK, and the few don't (IQR) have Pα >= 1.0 too (0.98 is the same as 1.00...).
ELMKIAQLAKRGP
HHHHHHHHHHH--
And be aware, the GP at the end is NOT a turn, because a turn is between two things! This
GP is just at the end, so it is a loop.
SNPAELLQALMKGS
--HHHHHHHHHH--
This is a short helix that sits bewteen two short loops (again, loops and not turns). The only non-AMELK
residue is Q, and Q has Pα > 1.0.

Many VITWYF residues and beautiful alternating phobics (-) abd philics (+)

Strand? + is out; - is in. One T points in, further all is OK. Many VITWYF residues.
A few hydrophobics point out but that is allowed. So: Strand!
VTITVEGPKITVE

β-hairpin? + is out; - is in and those are OK. Turn is GP is also OK. So, Hairpin!
SRGGEPTRHEAKE
---------HHHH
Beginning is a mess (aka loop). End can be helical, but 4 residues seems not much to decide that
something might be a helix. So, perhaps the beginning of a helix, but only perhaps.
ELLALKLLTVTVT
HHHHHHHHSSSSS 1
HHHHHHH-SSSSS 2
HHHHHHHH-SSSS 3
But you normally need HHH-SSS so solution 2 or 3. Look up Chou and Fasman parameters.
L is more 'expensive' in a helix than T in a strand. So, solution 3.
