acrylamide

Thân thiện

French fries contain acrylamide when cooked at high temperatures.

Definition

1. Noun:
   • A colorless, odorless, crystalline solid compound (chemical formula C₃H₅NO). It is classified as an amide derived from acrylic acid.
   • A chemical of significant industrial and research importance, but also a concern for human health. It is a neurotoxin and has been shown to be carcinogenic in studies on laboratory animals.

Examples of Usage

• Noun:
  • Acrylamide is used in the production of polyacrylamide polymers.
  • Scientists are studying how acrylamide forms in food during high-temperature cooking.
  • Occupational exposure to high levels of acrylamide can cause nerve damage.

Advanced Usage

• "Acrylamide formation": Refers to the chemical process, primarily the Maillard reaction, by which acrylamide is generated in starchy foods when they are baked, roasted, or fried at temperatures above 120°C (248°F).
  • Research focuses on methods to reduce acrylamide formation in potato chips and coffee.
• "Acrylamide exposure": Denotes the contact with or intake of acrylamide, whether through diet, occupation, or environment.
  • Regulatory agencies assess the risk from dietary acrylamide exposure to the general population.

Variants and Related Words

• Polyacrylamide (n): A polymer of acrylamide, widely used in water treatment, papermaking, and gel electrophoresis.
  • Polyacrylamide gels are essential for separating DNA fragments in the lab.

Synonyms

• Propenamide: The systematic IUPAC name for the same chemical compound.

Related Phrases / Contexts

• Potential human carcinogen: A classification given by health agencies based on sufficient evidence in animals but limited evidence in humans.
  • Due to animal studies, acrylamide is considered a potential human carcinogen.
• Food processing contaminant: A substance that is not intentionally added but is formed in food during its preparation or processing.
  • Acrylamide is a well-known food processing contaminant found in items like french fries and toast.
