Definition

1. Noun:
   • A type of lipoprotein: A specific class of molecule found in the blood plasma. Its primary function is to transport cholesterol from the liver to the tissues of the body. It is characterized by a composition containing a moderate amount of protein and a very large amount of cholesterol and other lipids. Elevated levels of this particle in the bloodstream are clinically significant and are considered a major risk factor for the development of coronary heart disease and atherosclerosis.

Examples of Usage

• Noun:
  • A high level of beta-lipoprotein is a key indicator for assessing cardiovascular risk.
  • The doctor explained that the patient's beta-lipoprotein concentration was too high.
  • Research focuses on how beta-lipoprotein contributes to plaque formation in arteries.

Advanced Usage

• Medical Context: In clinical and biomedical literature, "beta-lipoprotein" is often discussed in relation to lipid profiles, cholesterol management, and preventive cardiology.
  • The study measured the impact of the diet on beta-lipoprotein levels.

Variants and Related Words

• Low-Density Lipoprotein (LDL): This is the modern and more precise clinical term for "beta-lipoprotein." "LDL cholesterol" or "LDL" is almost exclusively used in current medical practice.
• "Bad" Cholesterol: A common layperson's term for the cholesterol carried by beta-lipoprotein (LDL), due to its association with heart disease.
• Lipoprotein: The general category of complex particles that transport lipids (fats) like cholesterol and triglycerides in the blood. Beta-lipoprotein is a specific type.

Synonyms

• LDL (Low-Density Lipoprotein): The direct and primary synonym.
• LDL cholesterol: Refers specifically to the cholesterol content within the beta-lipoprotein particle.

Related Phrases

• High beta-lipoprotein: A condition describing elevated levels in the blood.
• Beta-lipoprotein level: The measured concentration of this particle in a blood test.

Noun

1. a lipoprotein that transports cholesterol in the blood; composed of moderate amount of protein and a large amount of cholesterol; high levels are thought to be associated with increased risk of coronary heart disease and atherosclerosis
