What forces and bonds maintain the three dimensional folded shape of a protein molecule?
hydrogen bonds
What is the difference between molecular geometry and molecular structure?
Molecular geometry is the distances and angles between the each of the different atoms in the molecule. It is essentially the shape of the molecule.Molecular structure includes the shape of the molecule, but also much more, such as its electronic structure. This includes the nature of the bonding in the molecule (such as where there are single, double or triple bonds), the polarity of the molecule (if the electrons are spread out evenly throughout the molecule or if they are concentrated in particular areas, and if so, what areas), etc.
What does delocalized mean?
DelocalisedThe term 'delocalised' refers to an electron which is not 'attached' to a particular atom. For example, in metals, some of the outer electrons are delocalised and are free to move around the whole metal solid. This is why metals conduct electricity. Another example of delocalised electrons is in benzene (C6H6), a cyclic molecule composed of a ring of bonded carbons, with one hydrogen attached to each. In benzene, the electrons in the C-C pi-bonds (basically the double bonds) are delocalised the whole molecule. If you look at the location of these pi-bonding electrons, they are found evenly distributed in a ring around the entire molecule. In this case, the delocalisation can be explained by something called 'resonance forms.' Often, molecules with alternating double bonds show delocalised bonding.However, to truly understand the concept of delocalisation, some basic quantum mechanics must be used, and delocalised bonding in molecules is best explained by molecular orbital theory. In reality, all electrons are somewhat delocalised and are never associated with exactly one bond (in molecules with more than 2 atoms). Some are more localised than others (specific electrons stay mostly with specific bonds), while some are more delocalized (electrons are very free to move about many different bonds in the molecule)
Is carbon dioxide polar or non- polar?
It is a non-polar molecule. But it has polar covalent bonds between its atoms
HOW MUCH ENERGY IT TAKES TO ERASE ONE MOLECULE OF WATER ONE DEGREE?
A water molecule can be erased is the chemical bonds are destroyed. Although water is characterised as one oxygen atom attached to two hydrogen atoms, water molecules seldom exist in isolation: there are often clusters of four. This makes it much more difficult to calculate the amount of energy required to break the bonds and erase the water molecule from existence.
What forces and bonds maintain the three dimensional folded shape of a protein molecule?
hydrogen bonds
The stability of the three-dimensional shape of many large molecules is dependent on?
The stability of the three-dimensional shape of many large molecules is dependent on interactions such as hydrogen bonding, disulfide bridges, hydrophobic interactions, and electrostatic forces between different regions of the molecule. These interactions help maintain the specific shape and structure required for the molecule to function properly. Any disruption to these interactions can lead to loss of stability and functional changes in the molecule.
Why are there different ways of drawing covalent bonds?
Different ways of drawing covalent bonds, such as using Lewis structures, bond-line structures, or structural formulas, are used to represent the same molecule in different ways for different purposes. Lewis structures show the arrangement of valence electrons, bond-line structures are simplified representations for easier visualization, and structural formulas provide more detailed information about bond angles and lone pairs. Each method serves a specific purpose in communicating information about chemical structures.
Are covalent bond flexible?
Yes, covalent bonds are flexible to some extent. The electron sharing between atoms in a covalent bond allows for some movement and rotation, giving the molecule a certain degree of flexibility. However, the overall structure and shape of the molecule are still determined by the arrangement of atoms and the specific types of covalent bonds present.
What bond is formed in methane?
In methane, a covalent bond is formed between one carbon atom and four hydrogen atoms. This type of bond involves the sharing of electrons between the atoms.
How many bonds are necessary to form a ammonia?
There are three different covalent bonds in one molecule of ammonia
What is the chemical structure of the molecule?
I'd need to know the specific molecule you're referring to in order to provide its chemical structure. Each molecule has a unique arrangement of atoms and bonds.
The three-dimensional shape of the DNA molecule is described as being?
The three-dimensional shape of the DNA molecule is a double helix, which resembles a twisted ladder. This structure allows the molecule to have stability and store genetic information. The double helix is made up of two strands of nucleotides that are connected by hydrogen bonds.
What is it called when two different atoms combine?
When two different atoms combine, it is called a chemical bond. This can occur through different types of interactions such as covalent bonds, ionic bonds, or metallic bonds. The resulting molecule or compound formed can have different properties than the individual atoms.
What role do hydrogen bonds play in large molecules?
Hydrogen bonds help stabilize the three-dimensional structure of large molecules such as proteins and nucleic acids by forming interaction between different parts of the molecule. They contribute to the folding and shape of the molecule, influencing its function and biological activity. Additionally, hydrogen bonds can mediate interactions between different molecules, facilitating processes such as ligand binding and enzyme-substrate recognition.
When does the shape of a molecule affect it's polarity?
when the molecule contains polar bonds
What are three types of bonds which hold together molecules?
The three types of bonds that hold together molecules are covalent bonds, ionic bonds, and hydrogen bonds. Covalent bonds involve the sharing of electrons between atoms, ionic bonds involve the transfer of electrons between atoms resulting in oppositely charged ions attracting each other, and hydrogen bonds are not actual chemical bonds but are weak attractions between hydrogen atoms and electronegative atoms like oxygen or nitrogen.
