Introduction. Silicosis is a long-term lung disease caused by inhaling large amounts of crystalline silica dust, usually over many years. Silica is a substance naturally found in certain types of stone, rock, sand and clay.Working with these materials can create a very fine dust that can be easily inhaled.ilicosis is a long-term lung disease caused by inhaling large amounts of crystalline silica dust, usually over many years.
Phospholipids are a class of lipids that are a major component of all cell membranes. They can form lipid bilayers because of their amphiphilic characteristic. The structure of the phospholipid molecule generally consists of two hydrophobic fatty acid tails and a hydrophilic head consisting of a phosphate group.
The phospholipid has a strongly polar group, the phosphate group which is hydrophilic (likes water) and a lipid or fatty acid part that is hydrophobic (dislikes water), but at â¦ tracted to other lipids and fatty acids with what is called hydrogen bonds which are common between carbon-hydrogen chains.he phospholipids make up most of the cell membrane, the cell  membrane controls what goes in and out of cells and the  phospholipids helps with this because the 'heads' are â¦ hydrophilic  and the 'tails' are hydrophobic.
