Question
biochem Which one of these characteristics is not true for the helix? There are 3.6 amino acids per turn. There is a requirement for glycine every third ammo acid residue. A hydrogen bond forms between the carbonyl oxygen of the nth amino acid residue and the -NH group of the (n + 4)th amino acid residue. Proline is typically not found in the helix. It is right-handed. Which of these characteristics does not descnbe the sheet? Side chains are located both above and below the sheet sheets usually exhibit hght-handed twists. There are two forms, parallel and anti parallel. The sheets contain as few as two and as many as 22 polypeptide chains. Parallel D sheets containing fewer than five chains are the most common. Which statement below does not fibrous proteins? Domains are compact and globular. These proteins are usually dominated by a single type of secondary structure. These proteins usualy perform a protective, connective, or supportive role in the organism. Domains are usually stiff and elongated The proteins are usually water soluble What Kind of information is displayed in a Ramachandran plot? What is the biochemical basis for the disease scurvy? Why can uncharged polar residues such as Ser. Thr, Asn. Gin. and Tyr occur on the inside as well as the outside of a protein? What is the significance of Anfinsen's renaturation experiment? Why do proteins fold faster in vivo than in vitro?Explanation / Answer
