*There are two main types of cholesterol: [[high-density lipoprotein]] (HDL) and[[low-density lipoprotein]] (LDL). HDL is often referred to as "good" cholesterol because it helps remove excess cholesterol from the [[blood]] and transport it back to the [[liver]], where it can be broken down and eliminated. In contrast, LDL is often referred to as "bad" cholesterol because it can build up in the walls of the [[arteries]], leading to the formation of plaque and increasing the risk of [[heart disease]]. | *There are two main types of cholesterol: [[high-density lipoprotein]] (HDL) and[[low-density lipoprotein]] (LDL).

*While the [[body]] naturally produces [[cholesterol]], it is also possible to create cholesterol in a [[laboratory setting]]. This can be done using a process called [[total synthesis]], which involves [[synthesizing]] the [[molecule]] from simple [[building blocks]]. The process can be [[time-consuming and complex]], but it allows for the creation of large quantities of cholesterol for use in various [[applications]], such as the | *While the [[body]] naturally produces [[cholesterol]], it is also possible to create cholesterol in a [[laboratory setting]].

*One of the key steps in creating cholesterol in the laboratory is the formation of a molecule called [[squalene]], which is a type of [[hydrocarbon]]. Squalene is the starting point for the [[synthesis of cholesterol]], and it can be obtained from a variety of sources, including [[shark liver oil and yeast]]. | *One of the key steps in creating cholesterol in the laboratory is the formation of a molecule called [[squalene]], which is a type of [[hydrocarbon]].

*Once [[squalene]] has been obtained, it is subjected to a series of [[chemical reactions]] to convert it into cholesterol. The exact process depends on the specific method used, but generally involves the addition of functional [[groups]] and the formation of various [[intermediate compounds]].
