Amyloid-beta peptide is a protein that is found in the brain and is associated with Alzheimer’s disease. It is a small protein that is formed from the breakdown of a larger protein called amyloid precursor protein (APP). The accumulation of amyloid-beta peptide in the brain is believed to be one of the key factors in the development of Alzheimer’s disease.
Definitions
Amyloid-beta peptide is a small protein that is formed from the breakdown of amyloid precursor protein (APP). It is a major component of the amyloid plaques that are found in the brains of Alzheimer’s disease patients.
Origin
Amyloid-beta peptide is produced by the cleavage of amyloid precursor protein (APP). APP is a transmembrane protein that is found in many tissues throughout the body, including the brain. The exact function of APP is not fully understood, but it is believed to play a role in cell signaling and growth.
Meaning in different dictionaries
According to Merriam-Webster, amyloid-beta peptide is “a protein fragment that accumulates in the brains of people with Alzheimer’s disease and is believed to contribute to the development of the disease.”
The Oxford English Dictionary defines amyloid-beta peptide as “a small protein that is formed from the breakdown of amyloid precursor protein and is associated with the development of Alzheimer’s disease.”
Associations
Amyloid-beta peptide is strongly associated with Alzheimer’s disease. The accumulation of amyloid-beta peptide in the brain is believed to be one of the key factors in the development of the disease. Other associations include inflammation, oxidative stress, and neurodegeneration.
Synonyms
Synonyms of amyloid-beta peptide include beta-amyloid, Aβ, and amyloidogenic peptide.
