E and G were highlighted in red.

Not sure where to go from here.

Which statements are TRUE of a helices? Multiple answers: You can select more than one option O AFound in the same percentage in all proteins O B Stabilized by H bonds between -NH and-Co groups O CFound in globular proteins O D Affected by amino acid sequence OE An extended conformation of the polypeptide chain OF Includes all 20 standard amino acids in equal frequencies O GHydrophobic interactions are responsible for the primary structure

Explanation / Answer

Alpha helix is secondary structure of proteins and it has righthand spiral confirmation that is helix type.

Their N-H group donate a hydogen bond to backbone of carbonyl group of amino acid. It is present in all proteins with same percentage.

Hence all statements are true.

It is found in globular proteins.

It is affected by amino acid sequence because every CO group forms hydrogen bond with her group amino acid.

These forms the extended structure of polypeptide chain. As they have N-H and and C=O groups.the N- and -C capping preference of all 20 amino acids by substituting X residue in the peptides.

Hydrophobic interactions are responsible for the primary structure.l
