due to delocalization of the lone pair of electrons of the nitrogen onto
carbonyl oxygen
rigid because of the resonance stabilization of the amide (peptide) bond and the C=O (C double bond O) cause the structure to be planar and is therefore incapable of rotation.
This is called a peptide bond, or peptide linkage.
Yes, a peptide bond is a covalent bond.
there is no specific length for the peptide bond, but there are million amino acids that build up a peptide bond
They don't, exactly. However, both the nitrogen and the carbon participating in the bond are in the sp2 hybridization state, and this allows for a resonance structure making the group planar and restricting rotation about the carbon-nitrogen bond.
a peptide bond
An amide bond forming a chain of peptides. Peptide bond is only a special amide bond name for this particular bonding.
The formation of both the bonds is same but the term amide bond is used for simple molecules as CH3-CO-NH2 or CH3-CO-NH-CH3 etc. the term peptide bond is used for polymers where a large chain of polymer is formed due to amide bonds as in Di and poly peptide and also in proteins.
the bond connecting two aminoacid is peptide bond
If the peptide bond is hydrolyzed, then an H20 molecule is consumed.
A peptide bond
No, glycine is the simplest amino acid and does not have any peptide bond.
