Why is the peptide bond is considered rigid and planar? Please explain.
Why is the peptide bond is considered rigid and planar? Please explain.
In proteins, the peptide bond is formed between the carboxyl group of one AA and the amino group of a second. The four atoms in each peptide bond: terminate the protein are considered beta sheets insert kinks into alpha helices constitute nonpolar side chains form a rigid planar unit
Why are double bonds and peptide bonds more rigid than single bonds?
Are the following graphs planar? If so, show a planar representation and if not, explain why not. ь. Are the following graphs planar? If so, show a planar representation and if not, explain why not. ь.
Part 1 (1 point) See Hint Due to its partial double bond character, the peptide bond restricts rotation, constraining atoms to lie within the same peptide plane. Rotation in the peptide backbone is around the two bonds that flank adjacent Ca atoms, between which a peptide plane is formed. Part 2 (1 point) See Hint What is the molecular geometry of the constituents of the peptide plane? Choose one: A. The amide nitrogen is tetrahedral and the carbonyl carbon is...
Cholesterol is a rigid, planar molecule yet – when incorporated into a lipid membrane at low temperature – the fluidity of that membrane is enhanced, preventing transition to a gel-like state. Briefly explain this phenomenon
QUESTION 12 What is the function of a peptide bond? A peptide bond is responsible for the secondary structure of a protein. To join the amino group of one amino acid to the carboxy group of another amino acid, A peptide bond is responsible for the tertiary structure of a protein A peptide bond joins the phosphate group at the 6 carbon of a new nucleotide to the hydroxyl (OH) group of the 3' carbon of a nucleotide already in...
Which are true 1. a rigid body undergoing planar motion is pinned at the center of mass in the plane of motion; all non-CM points on the rigid body have the same angular velocity. 2. When a rigid body undergoes planar motion the body center of mass remains in a singular plane. 3. The normal force is never perpendicular to the surfaces that applies the normal force. 4. Mass moment of inertia of a rigid body indicates the magnitude of...
