What type of bond is found in all biological macromolecules?
depends on the macromolecule. the broad category would be "covalent bonds" ... but there are sort of subcategories... like, proteins are joined with peptide bonds (which occur through dehydrogenation - removal of a water molecule) protein folding is also a function of hydrogen bonding. long chain polycarbons are just covalently bound (carbon-carbon bonds) could be double or single bonds depending on degree of saturation
What is an atomic bond?
Atoms: atoms are the elements that cannot be futher divided by chemcal means. They are undivisible and cannot be broken down. They consist of electrons in their oribital shells, protons and neutrons in the nucleus. Atoms are arranged by atomic number on the periodic table of elements. Bonding: Bonding is when two or more atoms are bonded together by electrons to fulfill each other's outer valence shell to become a stable compound/molecule. :)
In DNA base pairs are held together by what kinds of bonds?
DNA base pairs are held together by Hydrogen Bonds. Adenine and Thymine have 2 bonds that hold them together while Cysteine and Guanine have 3 bonds that hold them together. The hydrogen bonds generally occur between a Nitrogen and a carbonyl oxygen.
Why are Adjacent water molecules connected by?
Its a weaker bond than covalent or ionic bonding. Its call Hydrogen Bonding. Do to the configuration of H20 positive and negative charges occur on the molecule. So specific areas such as the oxygen(w/ a slight negative charge) will attract to a hydrogen(w/ a slight positive charge) on a different H20 molecule. You can observer this phenomenon by observing that water has a surface tension.
During DNA replication what two processes must occur before the two stands of a DNA molecules can separate?
the hydrogen bonds between the nitrogen bases must be broken and the molecule must unwind.
How do you tell if a bond is covalent?
if it occurs between non metal atoms. Covalent bonds can only occur between non metal atoms but Ionic bonds occur between metal and non metal atoms.
How many bonds occur between two halogen atoms such as Cl2?
one
How is a covalent bond similar from an ionic bond?
They are not similar bonds. In fact, they are nearly opposite. Covalent bonds can occur between any two atoms and the bond is sharing electrons. Ionic bonds occur between any two different atoms and the bond is electromagnetic.
What type of bonding do lipids have?
The type of chemical bonds for lipids are nonpolar C-H bonds. The actual bonds that attach the fatty acids to the glycerol are refered to as ester linkages
Covalent bonds are formed between what types of elements or atoms?
Covalent bonds tend to occur between two Non- Metals.
What type of atoms do ionic bonds occur between?
well she is in the plain with the wayne and you call
What type of bond is in a lipid?
Nonpolar CH bonds. Ester linkages occur.
What is it called when changes occur when bonds form between atoms?
A chemical reaction, a chemical change.
What happens to bonds between atoms when chemical change occur?
An atom can gain, lose, or share.
What forms chemical bonds among atoms?
Chemical bonds form between atoms through the interaction of opposite charges. This process can occur between electrons and nuclei or as a dipole attraction.
Covalent bonds usually occur between atoms that have and?
Two atoms will form a covalent bond by the sharing of the valence electrons if the electronegativity difference between the two atoms is below 1.7
How can one describe the chemical bonds that occur between the two atoms of hydrogen to the one atom of oxygen in a molecule of water?
These are termed to be 'covalent bonds'.
