All cells use water as a solvent that creates the solution known as cytosol. What is Hydrophobic? These cookies help provide information on metrics the number of visitors, bounce rate, traffic source, etc. An example of a hydrophobic group is the non-polar methane molecule. In fact, oils are hydrophobic, or "water fearing." Instead of being attracted to water molecules, oil molecules are repelled by them. These cookies will be stored in your browser only with your consent. No it is hydrophilic as it contains no nonpolar groups which In a hydrophobic environment, the amino acid side chain is surrounded by non-polar molecules that don't interact well with water. A long string of amino acids becomes folded because of the various interactions it has with the other amino acids in the chain, as well as interactions with the environment. The amount of heat required to change the temperature of 1 g of any substance by one C is defined as the specific heat of that substance Nonpolar molecules that cluster away from water molecules are called __________ molecules.
