In terms of biochemistry, hydrophobia is the repulsion shown by a molecule to water. Lipids such as glycerol are a classic example, which is not soluble in water and will float on the surface.

What does a high Hansch hydrophobicity constant show?
A high Hansch hydrophobicity constant implies that the molecule is lipophilic.
Is ch3ch2ch2ch23n soluble in water?
I do not think that compound exists (as you have written it anyway). However, with the butyl chain, it is unlikely to have much solubility in water. Butane for example has 60mg per litre solubility in water which is very little. This is because it is an alkane chain which gives it hydrophobicity and water is very hydrophilic (these repel each other on a molecular level).
What is hydrophobic?
hydrophobicity (from the combining form of water in Attic Greek hydro- and for fear phobos) refers to the physical property of a molecule (known as a hydrophobe) that is repelled from a mass of water [1].Do you know how to use GOOGLE.Com?

What is are secondary databases in bioinformatics?
Those data that are derived from the analysis or treatement of primary data such as secondary structures, hydrophobicity plots, and domain are stored in secondary databases

What traits do drug molecules with branching tend to have?
They are less lipophilic than their corresponding straight-chained molecule. This is show by how molecules with branching with lower Hansch hydrophobicity constant values than their straight-chained counterparts.
What cause pearling of water in aquarium?
Transient "pearling" (drops of water resting on the water surface without merging with it) is the result of two forces: hydrophobicity of materials floating at the water surface, and the surface tension of the water itself. Generally speaking, various proteins and minerals disolved in the water can increase the surface tension, and bacteria, fatty acids, and certain proteins living on the water surface will increase the hydrophobicity there. You'll notice that there's more peraling in a tank where the water has been there a while as compared to one where the water is fresh.
Which solvent has the greatest lipid solubility Why do you think this?
The best lipid solvents are Hexane, Ethyl Alcohol and Methyl Alcohol. This is because lipids are nonpolar and hydrophobic. Hexane has the highest hydrophobicity of any solvent and is thus the best at dissolving hydrophobic molecules.
Are polysaccharides hydrophobic?
Yes. Sugars contain many polar hydroxyl groups, so they tend to be quite hydrophilic.

What is hard monomers and soft monomers?
The monomer can be categorized into three classes. The first two classes are characterized by their respective Tg values. Soft monomers, characterized by low Tg values, include n-butyl acrylate, 2-ethyl hexyl acrylate and iso-octyl acrylate. These monomers are longer chain alkyl acrylates and exhibit low water solubility (i.e., high hydrophobicity). Hard monomers, characterized by high Tg values, include styrene, methyl methacrylate, ethyl acrylate and methyl acrylate. The third class is the functional monomer with various functional groups, such as carboxyl or hydroxyl. Examples of functional monomers are acrylic acid and hydroxyethyl acrylate,which are very water-soluble. The hydrophobicity of the hard monomer depends on the monomer structure. Methyl acrylate and ethyl acrylate, which are short-chain alkyl acrylates, have higher water solubility.
Why 1-propanol is more hydrophobic or having lower polarity than 2-propanol?
The hydrophobicity of a molecule increases with longer contiguous chains of hydrocarbons. The -OH in 1-propanol is on the first of the three carbons, leaving the second and third carbons to form a larger hydrophobic molecular surface. In 2-propanol the OH on the central (second) carbon breaks up the overall surface hydrophobicity. The reason for this is that the O is an electron drawing group. As such, O will have an effect on the bonds between the C it's connected to as well as each bond made by that C. Also, the closer O is to another atom in the molecule, the stronger the effect. In 1-propanol, O is further from the third carbon, thus having a lesser effect on the dipole moment of that carbon. In 2-propanol, the O effects the dipole moments of the first and third carbons equally.
What is the antonym for example?
There is no antonym for example, you can't have no example. Therefore there is no antonym for example.
Where do the hormones move through the body?
....b/c hormones are hydrophobic and therefore do not dissolve in the plasma, they require proteins (ie albumin) to journey through the bloodstream. Once they reach their target cells they easily diffuse through the cell membrane due to their hydrophobicity and bind to their receptor within the cytoplasm. This complex (receptor-hormone complex) then travels to the nucleus of cell to regulate transcription to alter the amount of protein that is made.
