For the drug to get excreted into urine or bile it has to undergo a series of transformation which is called biotransformation. This process alters the lipophilic drugs to a polar object i.e. hydrophilic and is readily absorbed by body. With the addition of functional group in the 1st phase which included oxidization, reduction, hydrolysis etc. Than by undergoing synthetic phase i.e. addition of endogenous compounds, which make them readily absorbed.

Journal Article is sometimes called a Scientific Article, a Peer-Reviewed Article, or a Scholarly Research Article. Together, journal articles in a particular field are often referred to as The Literature.
Journal articles are most often Primary Research Articles. However, they can also be Review Articles. These types of articles have different aims and requirements. Sometimes, an article describes a new tool or method.
