Question 8 of 20 A protein's secondary structure arises due to interactions between amino acids. Two common secondary structures found in many proteins are $\alpha$-helices and $\beta$-sheets. Classify each description as characteristic of $\alpha$-helices or $\beta$-sheets. $\alpha$-Helices $\beta$-Sheets Answer Bank flat, pleated structure right-handed spiral around a central axis formed by the interaction of multiple strands can form a coiled-coil tertiary structure

36. A protein whose peptide backbone is mostly extended and hydrogen bonded to different strands of the protein is mostly composed of the secondary structure. 37. In an alpha-helix, the side chains on the amino acid residues: 38. Which one of the following is NOT a tertiary interaction in proteins?

Secondary Structure There are two main types of secondary structure that are name based on the order in which they were proposed and their shape. One is an alpha-helix and the other is a beta sheet. The same groups that worked on DNA structure also worked on protein structure. Linus Pauling proposed alpha helices and beta sheets and Crick proposed how alpha helices might fit together in a protein. The most common of these two structures in soluble proteins is the alpha helix. The dimensions of each structure are important for understanding the size of proteins and in our discussions of membrane proteins. Below please draw the structure of an antiparallel beta sheet indicating hydrogen bonds. Each strand will have the amino acid sequence AGGAG.
The secondary structure elements of proteins include alpha helices, collagen helices, beta strands, beta sheets, and beta turns. Match the secondary structure element on the left to one of its known attributes listed on the right. alpha helix collagen helix beta strand beta sheet beta turn [ Choose ] covalently linked to vitamin C stabilized by S-S bonds pitch = 3.6 amino acids leucine is required every 7th amino acid hairpin element extended chain repeated GXY where X & Y are commonly Pro stabilized by H-bonds between adjacent strands
