tristearin

Thân thiện

A scientist examines a sample of tristearin in a laboratory.

Definition

1. Noun:
   • A triglyceride of stearic acid: Tristearin is a specific type of fat (lipid) molecule. It is formed when three molecules of stearic acid (a common saturated fatty acid) bond to a single molecule of glycerol. It is a solid at room temperature and is found in some animal and vegetable fats.

Usage Examples

• Noun:
  • The chemical analysis confirmed the presence of tristearin in the sample.
  • As a pure triglyceride, tristearin has a very high melting point.

Advanced Usage

• In Chemistry and Biochemistry: The term is used precisely to describe this specific triester of glycerol. It is often discussed in contexts involving lipid chemistry, soap manufacturing (as saponification of tristearin produces stearic acid salts), and food science.
  • The saponification of tristearin yields glycerol and sodium stearate, a common soap.

Variants and Related Words

• Stearin: A broader, sometimes less precise term that can refer to tristearin specifically or to mixtures of triglycerides rich in stearic and palmitic acids.
• Triglyceride: The general class of compounds to which tristearin belongs; an ester derived from glycerol and three fatty acids.
• Stearic Acid: The specific saturated fatty acid (C₁₇H₃₅COOH) that is the component of tristearin.

Synonyms

• Glyceryl tristearate: The systematic chemical name for tristearin.
