Vitamin
Glossary "H"
- HDL cholesterol-
a cholesterol-poor, protein-rich lipoprotein
of blood plasma associated with a reduced risk of atherosclerosis.
- HDL-high
density lipoproteins- a fat-transporting
fraction of blood higher levels of which are
believed to be associated with a reduced risk of
heart disease.
- hemiplegia-
paralysis of only one side of the body.
- hemoglobin- the
iron-containing pigment of the red blood cells.
- hemolysis-bursting
(lysis) of red blood cells. One way of measuring
vitamin E deficiency is by finding out how easily
the red blood cells burst when subjected to lysing
agents such as hydrogen peroxide. Higher serum
levels of vitamin E protect the red blood cells
against hemolysis, unless they are then exposed to
even higher concentrations of the oxidant hydrogen
peroxide.
- hemorrhage- heavy
or uncontrollable bleeding.
- hepatic-
hepatics aid the liver by toning and strengthening
it and in some cases increasing the flow of bile.
They are fundamental in maintaining health because
of the important role the liver plays by not only
facilitating digestion but also removing toxins from
the body.
- hepatoxic- any
substance which is toxic
to the liver.
- -5-HIAA-5-hydroxyindoleacetic
acid- a breakdown product of the
neurotransmitter serotonin.
- histamine- a
substance produced by the body during an allergic
reaction.
- histone- a basic
protein associated with nucleic acids. Histones are
important parts of the DNA control system,
suppressing the expression of or causing the
expression of specific parts of the DNA blueprints
in conjunction with other nucleoproteins.
- hormone- a chemical
messenger that is transported (often by the
bloodstream) a relatively long distance from its
source to the cells it affects. Insulin, vasopressin,
testosterone, and cortisone are all examples.
- hydroperoxide-a
type of organic peroxide.
- hydroxyl radicals-
a particularly reactive, damaging type of free
radical, formed when superoxide radicals react with
hydrogen peroxide. Hydroxyl radicals are thought to
be the principal damaging agent to joint membranes
in arthritis. X-rays do most of their damage via
hydroxyl radicals. Hydroxyl radicals can attack and
damage any molecule in your body.
- hypothalamus-
the master gland of neuroendocrine (hormone) control
in the brain. It controls the pituitary's production
and release of its own hormones. Appetite and body
temperature control centers are located in the
hypothalamus. It releases many hormones including
LHRH, a natural aphrodisiac. An aging clock or
clocks may be located in the hypothalamus.
- hypoxia- a condition
of oxygen deficiency (but not total absence) in part
or all of the body. Under conditions of hypoxia,
free radical production is often greatly stimulated.
