Usage

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.

Uses

Different sources of media describe the Uses of 123-94-4 differently. You can refer to the following data:
1. glyceryl stearate SE is self-emulsifying glyceryl stearate. It provides a stable, uniform oil-in-water emulsion.
2. Monostearin (1-Stearoyl-rac-glycerol) is used in the development of drug delivery vehicles such as nanoparticles and microemulsions.

Definition

ChEBI: A rac-1-monoacylglycerol composed of equal amounts of 3-stearoyl-sn-glycerol and 1-stearoyl-sn-glycerol.
