Question

Understand alpha helices and beta pleated sheets Question How is it possible for the a-helix to have amino acids with bulky side chains while the B-pleated sheets cannot? Select the correct answer below: O The R groups in the a-helix stabilize the structure, while they interfere with the hydrogen bonds in a B-pleated sheet. The R groups are contained inside the a-helix structure, while they interfere with the hydrogen bonds in a B- pleated sheet. O The R groups lie outside the a-helix structure, while they interfere with the hydrogen bonds in a b-pleated sheet. O groups can fit and The a helix structure allows any size R group to help stabilize the form, while only small form the bonds necessary to stabilize a B-pleated sheet.

Answer 1

A Acidic and basic R-groups of amino acids affects the isoélectric point (st): - The Essekeetrine point = Net charge of amino acid te cpt is zero Hence, The isolectric point is lowered by acidic R- groups and raised by Basic R-groups.
