Apolipoprotein B (Overview)

Apolipoprotein b (apob) is a protein present on the surface of low density, intermediate density, very low density, and chylomicron lipoprotein particles. There is 1 molecule of apob per particle. In fasting samples 90-95% of apob is bound to LDL particles. As a result, apob is used analytically as an estimate of the number of LDL particles.

Why would a person need a serum apolipoprotein b measurement?

Why would a person need a serum apolipoprotein b measurement?

Not a routine test: The general consensus is that apolipoprotein b levels do not provide more information than LDL levels. The exception being rare metabolic disorders. ...Read more

Why would a person need a serum apolipoprotein a-i level test?

Why would a person need a serum apolipoprotein a-i level test?

Heart risk: Hi. Apo A1 is the most predominant apolipoprotein associated with HDL (the lipoprotein class that correlates with protection from heart attack risk), and Apo A1 independently is inversely related to heart attack risk (higher serum Apo A1 correlates with lower heart attack risk). In measuring blood tests to try to assess heart attack risk, therefore, serum Apo A1 may be helpful. ...Read more

Doctors, what is the difference between apolipoprotein and chylomicron?

Doctors, what is the difference between apolipoprotein and chylomicron?

Particle vs. Protein: Hi. Chylomicrons are a class of lipoprotein particles that are produced by the intestines to mobilize and transport non-water soluble dietary lipids (from food) via the thoracic duct into the blood, and from there, deliver fats to tissues and the remnant to the liver. There are many different apolipoproteins that serve structural & metabolic roles for various lipoproteins (chylos, VLDL, LDL, HDL) ...Read more

Why different lab normals for lipid profle (with apolipoproteins) from one lab to the next, what should the apo b to apo a-1 ratio be?

Why different lab normals for lipid profle (with apolipoproteins) from one lab to the next, what should the apo b to apo a-1 ratio be?

Differnt methods: Different methods will often give different results. In any case apoprotein ratios do not add useful information to the basic total cholesterol, HDL and triglyceride tests. ...Read more

How do drug treatments for Alzheimer's disease effect the risk gene apolipoprotein e-e4?

How do drug treatments for Alzheimer's disease effect the risk gene apolipoprotein e-e4?

They don't: Drug treatments for alzheimer's don't affect genes like apo e4. Their intent is to treat the aftermath (the cognitive symptoms of alzheimer's disease itself). Young people with this gene should read dr. David perlmitters new book, "grain brain, " which makes a strong research-based case for gluten and other sugars being linked to alzheimer's and many other problems. Http://tinyurl.

I have these little white headed tiny bumps on top of my skin where the hip bones are, they don't hurt or itch, it is almost as if my jeans rub to much there but I rarely wear jeans or tight clothes that would rub?

I have these little white headed tiny bumps on top of my skin where the hip bones are, they don't hurt or itch, it is almost as if my jeans rub to much there but I rarely wear jeans or tight clothes that would rub?

Keratosis pilaris: Small white bumps on the skin, especially of legs and arms can be due to Keratosis pilaris. Sometimes this is due to dry skin, or mild irritation. Use fragrance free skin care products, don't scrub too hard, and moisturize daily and see if that helps. If this is no help get seen by a doc to see exactly what is going on. See http://tinyurl.

Do jointex contain vit b at all?

Do jointex contain vit b at all?

Check the label: Jointex comes in several varieties. Some may contain one or more of the b vitamins. It would state so on the label. Being a "supplement" and not an fda approved medication, jointex probably doesn't have scientific research evidence to back up it's advertised uses. ...Read more

Should people get a hipitis B shot?

Should people get a hipitis B shot?

Probably: Hepatitis B is an effective vaccine and all children have been routinely vaccinated since 1991. For adults the usual recommendation is to vaccinate if there is any risk of exposure (healthcare workers, people with immunodeficiency, etc). More recently the vaccine is being offered to all adults. ...Read more
