Apolipoproteins are polar structures which provide structural stability to the lipoprotein and act as receptors that help to determine the fate of the particle. Some act as cofactors for enzymes involved in lipid and lipoprotein metabolism.

Apolipoprotein A-1 (ApoA-1) tar kolesterol och triglycerider till levern för att utsöndras och kan jämföras med det goda HDL-kolesterolet. Kolesterol och triglycerider är mycket olösligt i vatten och är därav i behov av proteiner för att kunna transporteras runt i blodet.

Apolipoproteins are proteins that bind lipids to form lipoproteins. They transport lipids in blood, cerebrospinal fluid and lymph. The lipid components of lipoproteins are insoluble in water. However, because of their detergent-like properties, apolipoproteins and other amphipathic molecules can surround the lipids, creating a lipoprotein particle that is itself water-soluble, and can thus be carried through water-based circulation. In addition to stabilizing lipoprotein structure and solubilizi Apolipoprotein (apo) A-I accounts for 70% of the total protein in high-density lipoprotein (HDL) and plays a key role in HDL biogenesis and function. Analyses of the apoA-I amino acid sequence have revealed that most of its 243 amino acid residues are grouped into amphipathic α-helices of 11 or 22 amino acids in length.

Accordingly, antibodies specific for each apolipoprotein should be considered important research and diagnostic tools. Rockland produces highly specific antibodies to apolipoproteins. Rockland purifies apolipoprotein antibodies from hyper-immune serum by immunoaffinity chromatography followed by extensive cross adsorption to remove unwanted reactivity and generate precise specificities. Apolipoprotein (zkracován jako Apo) či apoprotein je z definice bílkovinnou složkou lipoproteinů. V lipoproteinech se vyskytují v různém množství, od méně než 1 % u chylomikronových částic po více než 70 % u HDL lipoproteinů. Information om Apolipoprotein B (Apo B).

Apolipoprotein A-I (apo A-I) may be ordered, along with other lipid tests, as part of a profile to help determine a person's risk of developing cardiovascular disease (CVD). It may be used as an alternative to a high-density lipoprotein (HDL) test , but it is not generally considered "better" or more informative than HDL and is not ordered routinely.

It helps start the process for HDL to remove bad types of cholesterol from your body. In this way May 24, 1990 As we have shown, apolipoprotein(a) is genetically polymorphic, and lipoprotein( a) levels in plasma are largely determined by several alleles at Not recommended for cardiovascular disease risk assessment. Use to detect the very rare familial alpha-lipoprotein deficiency.

It helps start the process for HDL to remove bad types of cholesterol from your body. In this way, apolipoprotein A can help to lower your risk for cardiovascular disease. Apolipoprotein A levels can be measured. Apolipoprotein A-I (ApoA-I), the major protein component of high-density lipoproteins (HDL) is a multifunctional protein, involved in cholesterol traffic and inflammatory and immune response regulation.

Apolipoprotein A-I (ApoA-I), the major protein component of high-density lipoproteins (HDL) is a multifunctional protein, involved in cholesterol traffic and inflammatory and immune response regulation. Many studies revealing alterations of ApoA-I during the development and progression of various types of cancer suggest that serum ApoA-I levels may represent a useful biomarker contributing to 2012-10-03 2019-07-02 We did two randomised, double-blind, placebo-controlled trials. In a phase 2 trial (done in 13 study centres in Canada, the Netherlands, Germany, Denmark, and the UK), we assessed the effect of IONIS-APO(a) Rx, an oligonucleotide targeting apolipoprotein(a).Participants with elevated Lp(a) concentrations (125–437 nmol/L in cohort A; ≥438 nmol/L in cohort B) were randomly assigned (in a 1:1 Stepwise discriminant analysis indicates that smoking, hypertension, decreased apolipoprotein A-I, increased apolipoprotein B, increased Lp(a) and diabetes are all significant (p less than 0.05) factors in descending order of importance in distinguishing patients … apolipoprotein A-I: an apolipoprotein found in HDL and chylomicrons.

It is an activator of LCAT and a ligand for the HDL receptor. A deficiency of this apolipoprotein has been associated with low HDL levels and with Tangier disease. Breslow et al. (1982) isolated and characterized cDNA clones for human apoA-I. Apolipoprotein A-I is the major apoprotein of high density lipoprotein (HDL) and is a relatively abundant plasma protein with a concentration of 1.0-1.5 mg/ml.
