I need help with one of the questions on my biochemistry assignment

Choose the correct statement on proteins: a) proteins are folded by alpha-helix b) proteins can preserve their function even if they only partially change their shapes c) proteins are composed of amino acids d) all of the above

Thanks in advance! :)

a) is wrong because proteins are not folded by alpha-helix. Alpha-helix isn't something that folds proteins, it is a shape. In addition, proteins may be folded in beta sheets instead of alpha helices. c) is definitely the correct answer. – Mew Sep 25 '13 at 1:57
@Biochemistry Student The answer should be C) – biogirl Oct 1 '13 at 18:17

Do you have a textbook? That will definitely have the answer early on in the chapter. Also, have you tried reading the protein Wikipedia article, in particular the structure subsection. You will find the information you want there.

My textbook is "Bioprocess Engineering, Basic Concepts". I think the answer is either c) or d)all of the above..thanks for the article – Biochemistry Student Sep 24 '13 at 21:33
