Explanation
• “Folic acid is a hematopoietic water soluble vitamin”.
• “Folic acid is a hematopoietic water soluble vitamin”.
•
Water-soluble vitamins differ from fat-soluble vitamins in several respects.
Most arereadily excreted once their concentration surpasses the renal
threshold. Thus toxicities are rare. Deficiencies of these vitamins occur
relatively quickly on an inadequate diet.
•
Their metabolic stores are labile and depletion can often occur in a matter of
weeks or months. Since the water-soluble vitamins are coenzymes for many common
biochemical reactions, it is often possible to assay vitamin status by
measuring one or more enzyme activities in isolated red blood cells.
•
These assays are especially useful if one measures the endogenous activity and
the stimulated activity following addition of the active coenzyme derived from
that vitamin.
