| Questions And Answer | Back Directory | [Description]
Monostearin (also known as 1-Stearoyl-rac-glycerol) is a long chain molecule typically occurring in the body as a by-product of the breakdown of fats. It is one of the panels of serum metabolic biomarkers for detecting and diagnosing cancer, especial ovarian cancer. It is also used in the development of drug delivery vehicles such as nanoparticles and microemulsions. It can also be used as an emulsifying agent, which allows the suspension of pharmaceuticals in a biodegradable form.
