Definition

1. Adjective:

   • Resembling starch: Having a physical or chemical similarity to starch, often used in scientific contexts to describe substances or structures.

2. Noun:

   • (Pathology) A waxy, translucent complex protein: An abnormal, insoluble protein that accumulates in tissues during certain diseases, resembling starch in some of its properties.
   • A non-nitrogenous food substance consisting chiefly of starch: (Less common, historical usage) Any starchy substance or a substance resembling starch.

Examples of Usage

• Adjective:

  • The biopsy revealed amyloid deposits in the organ. (The biopsy showed deposits resembling starch in the organ.)
  • Under the microscope, the material had an amyloid appearance. (Under the microscope, the material had an appearance similar to starch.)

• Noun (Pathological):

  • Alzheimer's disease is associated with the formation of amyloid in the brain. (Alzheimer's disease is connected to the formation of this waxy protein in the brain.)
  • The doctor identified the substance as amyloid. (The doctor identified the substance as the abnormal protein.)

• Noun (Historical/Biochemical):

  • Older texts sometimes refer to starchy foods as amyloid. (Older texts sometimes call starchy foods by this term.)

Advanced Usage

• "Amyloid plaque": A specific cluster or deposit of the abnormal amyloid protein, often in the brain.

  • Researchers are studying how to clear amyloid plaques. (Researchers are studying how to remove these protein clusters.)

• "Amyloidosis": A group of diseases characterized by the buildup of amyloid proteins in various organs.

  • He was diagnosed with systemic amyloidosis. (He was diagnosed with the disease where amyloid builds up throughout the body's systems.)

Variants and Related Words

• Amyloidogenic (adj): Having the potential to form amyloid.

  • The scientist studied the amyloidogenic properties of the peptide. (The scientist studied the peptide's properties that could lead to amyloid formation.)

• Amyloid precursor protein (APP): A protein from which amyloid peptides can be derived.

  • Mutations in the gene for APP can lead to amyloid production. (Changes in the gene for this precursor protein can cause amyloid to be made.)

Synonyms

• Starchlike (adj): Resembling starch (for the adjective form).
• Amylaceous (adj): Having the nature of starch.

Related Phrases

• "Amyloid beta" (Aβ or Abeta): A specific peptide that forms the amyloid plaques found in the brains of Alzheimer's patients.

  • The drug aims to reduce levels of amyloid beta. (The drug aims to lower the amount of this specific peptide.)

• "Amyloid fibril": The insoluble, fibrous structure formed by aggregated amyloid proteins.

  • The stability of amyloid fibrils makes them difficult to break down. (The strength of these fibrous structures makes them hard to destroy.)
