Homocysteine: What is it?
Homocysteine is an amino acid.
If you recall, amino acids are the building blocks of proteins. The only
source of homocysteine for use in our bodies is that which is formed by
the liver after the ingestion of another amino acid, methionine. Methionine
is found in protein foods, animal protein contains two to three times the
amount of methionine as does plant protein.
Homocysteine: What does it
do?
The amino acid participates in
essential metabolic pathways of some vitamins. The problem with homocysteine
is that even though 70% is bound to plasma proteins in the blood stream,
it is a potent toxin to cells that line blood vessels (endothelial or intimal
cells) and interacts with specialized proteins and cells in the blood causing
blood to easily clot. The toxicity directed at the endothelial cell
when combined with blood clot promotion is a lethal marriage capable of
producing heart attacks, strokes, pulmonary embolism. In addition, homocysteine
worsens blood vessel narrowing in those with kidney diseases and diabetes
mellitus.
Homocysteine toxicity: How
do we stop it?
In order to understand how to stop
homocysteine toxicity you must understand its mechanisms of action. Part
of the purpose of this web site is to inform you about the significant
potential toxicity of homocysteine so that you can be armed with facts
to take back to your family and friends including your physician. I can
almost guarantee you that your physician is not well informed about the
dangers of homocysteine.
This forum will be used to unfold all the known homocysteine toxicities (and there are many) and how each may be prevented. In most instances we will be recommending therapy with various B vitamins and the ingestion of fresh healthy fruits and vegetables. We shall show that for many of you, a normal American diet can not supply the concentration of B vitamins necessary to detoxify homocysteine. That this is true has been scientifically documented by many clinical nutrition studies.
