Physical properties
Triglycerides are colorless, although degraded samples can appear yellowish. Stearin, a simple, saturated, symmetrical triglyceride, is a solid near room temperature, but most examples are oils. Their densities range from around 0.89 with very long-chain fatty acids, through about 0.93 to 0.98 with medium-chain, and above 1.0 for very-short-chain acids.
