The peptide linkage in proteins has an NH group (secondary amine) and a CO group (ketone). The O in the CO can form a hydrogen bond with the H in the NH on a different residue. There are two really good conformations to allow a lot of residues to participate in hydrogen bonding. One is the alpha-helix, where the peptide backbone is in a spiral configuration and the hydrogen bond is between peptide linkages a couple of residues apart: counting the first one as 1 and going along the chain, the one it bonds to would be 4. If the helix continues long enough, 2 would bond to 5, 3 would bond to 6, 4 would bond to 7 in addition to its bond with 1, and so forth. Except for the ends, each residue then gets to participate in two hydrogen bonds so the alpha-helix is a particularly stable structure and occurs in many proteins. The other is the beta-sheet, where the residues may be a considerable distance apart along the chain. The backbone is essentially flat, and another segment runs parallel to it; the overall effect is something like a zipper or a set of railroad tracks where the "ties" are hydrogen bonds. It's possible to then put ANOTHER segment parallel on the other side, so again each residue can participate in two hydrogen bonds; beta-sheets are also a particularly common conformation. In a beta-sheet, the two "edge" segments only can hydrogen bond on one side, but there's a structure seen in several proteins called a beta barrel which is, basically, a beta-sheet rolled into a cylinder (the individual segments are then like staves in a barrel, hence the name).
This is a covalent bond.
The most common bond in hydrogen is a compound one.
the chemical bond that water has is called covalent bond where there are two hydrogen atoms and an oxygen atom
A weak chemical bond between a partially positive hydrogen atom and a partially negative atom is known as a hydrogen bond. This type of bond occurs when the hydrogen atom, which is covalently bonded to a more electronegative atom, is attracted to another electronegative atom nearby. Hydrogen bonds play a crucial role in the properties of water and the structure of proteins and nucleic acids. Although they are weaker than covalent and ionic bonds, they are significant in maintaining molecular structures and interactions.
Hydrogen bond doesn't involve neutrons. A hydrogen bond is the electromagnetic attractive interaction of a polar hydrogen atom in a molecule or chemical group and an electronegative atom, such as nitrogen, oxygen or fluorine, from another molecule or chemical group.
Hydrogen atom doesnt have a chemical bond but dihydrogen molecule has a sigma bond between the two hydrogen atoms
peptide bond, hydrogen bond
The chemical bond between chlorine and hydrogen is polar covalent.
This is a covalent bond.
A hydrogen bond is a type of weak chemical bond that holds together molecules or parts of molecules where hydrogen is covalently bonded to a highly electronegative atom. This bond is commonly found in water molecules, DNA strands, and proteins, which allows molecules to interact and form specific structures such as double helix in DNA or secondary structures in proteins.
A hydrogen bond.
which is not a type of chemical bond, covalent, electron, ionic, or hydrogen
The most common bond in hydrogen is a compound one.
the chemical bond that water has is called covalent bond where there are two hydrogen atoms and an oxygen atom
A hydrogen bond is a type of chemical bond. A hydrogen atom bonds with either a nitrogen, fluorine, or oxygen atom to make a weak bond.
Covalent
yes
