What type of compound is bio diesel made from?

Biodiesel is primarily made from triglycerides, which are esters formed from glycerol and fatty acids. These fatty acids can be sourced from vegetable oils, animal fats, or recycled cooking oils. The process of transesterification converts these triglycerides into fatty acid methyl esters (FAME), which constitute biodiesel, along with glycerol as a byproduct.
