A "hydrophobic" amino acid is an acid that "fears" water. When in contact with water, the hydrophobic amino acid will cause that section of protein to stay away from water.

Chemically orthogonal means that two functional groups or molecules do not engage in similar/identical chemical reactions or exhibit significant differences in their chemical reactivities. An amino and a nitro are chemically orthogonal nitrogen-functions. On the other hand, an aldehyde and a ketone can be considered chemically very similar with respect to most reaction conditions. I have to admit that this terminology is rather general and does apply to many functions. It is probably not of too much use.

The answer depends on the formulation. Some are meant to dissolve later in the digestive tract than others, and some are meant to be absorbed through skin or mucous membranes.
The side chains of some amino acids are hydrophobic but not all. You can see the molecular structure of those that have hydrophobic side chains by going to http://tinyurl.com/ycyj645.

if you meant what is Protein in? Eggs (the white), steak, fish, chicken, cheese (lots fat too!). or if you meant what you meant... Amino acids.
Amino acids are the building blocks of proteins. Proteins are simply chains of amino acids. I think you meant to ask do proteins have amino acids. Amino acids as the name indicates (Amino) have amine groups, carboxylic acid groups and a side chain that varies depending on the amino acid (20 differnet types).
It depends on the physical properties of the substance. Sometimes heating a hydrophobic substance can increase solubility. Also, heating may cause the substance to denature and dissolve. In the case of proteins, proteins can contain many hydrophobic parts but still be soluble in water. However, hydrophobic substances do not typically dissolve in water, due to the polar nature of water. Typically, scientists use the word "hydrophobic" only to describe substances that have a negligible solubility in water. You may have meant to ask "why do hydrophilic substances dissolve in water".
membrane are composed of a lipid bilayer. their hydrophobic tails face the inside of the membrane and their hydrophilic heads face their environment.
Protease is an enzyme so it would break down into amino acids. (If you meant protein then the same is true)
There are 20 common amino acids (pre-modification). In a set of any four, each one could be one of 20, meaning there are 204 possible combinations: 160,000. If the question was meant to be "how many amino acids can be made from 4 triplet codons then the answer would still be exactly the same. Even though there are 4 bases, meaning there are 64 different codes possible, there are still only 20 amino acids available. If the question was meant to be "how many amino acids can be made from 4 bases" you can only make one (which could be any of 20 different residues), as you need three bases to code one amino acid. See the related question below for a listing of the types of amino acids.
When an amino acid chain structure folds together and winds in and out of each other.
The last stage in the formation of a protein, when the amino acid chains fold in on themselves for the fourth and final time.
This is the process of people learning by watching the behavior of others. They learn how to change and control their own behavior by seeing how others behave.
Basically it means driving as if all other users are likely to do something wrong. Be prepared for the unexpected and do not assume people will behave as they should.
