High Density Lipoprotein Cholesterol, or HDL-C, is a compound composed of lipids and proteins that carries cholesterol in the body. In IPA phonetic transcription, the word is spelled [haɪ] [ˈdɛnsɪti] [lɪpəʊˌprəʊˌtiːn] [kəˈlestərɒl]. The "h" in "high" is pronounced as [haɪ], while "density" is pronounced as [ˈdɛnsɪti]. "Lipoprotein" is pronounced as [lɪpəʊˌprəʊˌtiːn], and "cholesterol" as [kəˈlestərɒl]. The spelling of the word accurately represents the sounds of each syllable, helping medical professionals correctly identify and
High Density Lipoprotein Cholesterol (HDL cholesterol) is a type of cholesterol that plays a crucial role in maintaining optimal cardiovascular health. It is a lipoprotein particle that consists of a core of cholesterol and triglycerides surrounded by a shell composed of proteins, phospholipids, and cholesterol.
HDL cholesterol is often referred to as the "good cholesterol" because it plays a protective role against the development of cardiovascular diseases. It acts as a scavenger, removing excess cholesterol from the bloodstream and transporting it back to the liver for processing and removal from the body. HDL cholesterol also possesses anti-inflammatory, antioxidant, and antithrombotic properties, which further aid in maintaining the health of blood vessels and preventing arterial plaque formation.
A high level of HDL cholesterol has been associated with a reduced risk of developing heart disease and stroke. It helps to maintain the balance between the "good" and "bad" cholesterol in the body, as it counters the negative effects of Low Density Lipoprotein (LDL) cholesterol, also known as the "bad cholesterol."
A healthy level of HDL cholesterol is typically considered to be over 40 mg/dL for men and 50 mg/dL for women. Factors such as genetics, lifestyle choices, and certain medications can influence HDL cholesterol levels. Regular physical activity, a balanced diet, avoiding smoking, and maintaining a healthy weight are all recognized as lifestyle measures that can help increase HDL cholesterol levels and reduce the risk of cardiovascular diseases.
