When a protein is folded in a cellular environment, side chains of hydrophobic amino acids will cluster in the core of the protein to avoid contact with water, whereas the hydrophilic side chains are exposed on the surface of the protein and are free to form hydrogen bonds with water molecule...
Why is the formation of hydrogen bonds categorized as cohesion? How does hydrogen bonding between water molecules affect the properties of water? Why is hydrogen important in our bodies? Why are chemical bonds important? Why does water need a specific type of bond in the body?
Hydrogen bonds: why life needs waterS.E. Gould
Pyridine will dissolve in water because of the strong hydrogen bonds (or dipole-dipole intermolecular interactions) that exist between the lone pair of electrons
Water is said to be polar because there is a net negative charge at the Oxygen end of the molecule and a net positve charge at the hydrogens end of the molecule. Water molecules therrefore behave like magnets in that they arrange themselves such that hydrogen bonds form between the hydrogen...
Base pairing between the two strands of DNA occurs by means of: a) Hydrogen bonding b) Coordinate covalent bonds c) Ionic bonds d) Disulfide bonds Any water molecule has the ability to form hydrogen bonds with other water molecules.
Moreover, similar analysis on some hydrogen bonded complexes confirms that beyond this angle the acceptor atom Y starts interacting with the atomic basin on X. However, conclusions based on bond lengths and angles have to be treated with care and as the IUPAC recommendation points out that ...
and their ability to form hydrogen bonds with water decreases. So they’re really acting as water-in-oil emulsifiers when heated. As the lotion cools,the HLB of these emulsifiersstarts to increase back to the proper HLB value and their ability to hydrogen bond with water increases. The loti...
Why is {eq}CH_4 {/eq} not capable of forming hydrogen bonds?Methane:Methane ({eq}\rm CH_4 {/eq}) is the smallest alkane and commonly found as part of natural gas or as emissions from metabolic processes of methanogenic microorganisms. It is a potent greenhouse gas whose emissions are ...
Water is less dense in its frozen form, ice, than it is in its liquid form. This is because the molecules in ice are further apart than the molecules in liquid water. The molecules in ice are held further apart by the hydrogen bonds between the oxygen and hydrogen atoms. ...
