PHOSPHORUS
Submitted by:
UMESH MASKARE
M.Sc (FST) 1st year
German chemist Hennig Brand in 1669, discovered
phosphorus from urine.
Urine was having considerable quantities of
dissolved phosphates from normal metabolism.
In 1769 Johan Gottlieb Gahn and Carl Wilhelm
Scheele showed that calcium phosphate is found
in bones, and they obtained elemental phosphorus
from bone ash.
HISTORY
It is generally colourless.
It is odourless.
It is non-volatile.
PROPERTIES
 Phosphorus plays a major role in the structural
framework of DNA and RNA.
 Living cells use phosphate to transport cellular energy in
the form of adenosine triphosphate (ATP).
 Phospholipids are the main structural components of all
cellular membranes.
 Calcium phosphate salts assist in stiffening bones.
Role
 Milk
 Meat
 Soyabean products
 Eggs
 Seeds and nuts
 Fruits and vegetable
Sources
 It is absorped after release of Parathyroid hormone due to
low phosphorus level.
 Its absorption also requires presence of vitamin D binding
complex to get it absorped through small intestine.
 Nearly 70-80% of phosphorus absorped is bound to food we
eat.
 Other minerals have the same site for absorption and hence
compete with it hindering absorption of phosphorus.
Absorption
 0 to 6 months: 100 mg/day
 7 to 12 months: 275 mg/day
 1 to 3 years: 460 mg/day
 4 to 8 years: 500 mg/day
 9 to 18 years: 1,250 mg
 Adults: 700 mg/day
 Pregnant or lactating women: Younger 1,250 mg/day
RECOMMENDED DIETARY
ALLOWANCES
 HYPO PHOSPHATEMIA:
Low levels of soluble phosphate in the
blood serum and inside the cells.
Symptoms: Neurological dysfunction and disruption of
muscle and blood cells due to lack of ATP.
 HYPER PHOSHATEMIA:
Too much phosphate.
Symptoms: diarrhoea and calcification (hardening) of organs
and soft tissue.
Deficiency
 Phosphorus is an important mineral.
 It has various vital role in proper functioning
and metabolism of body.
 Required amount of phosphorus should be
consumed so that no deficiency will occur.
Conclusion
Thank you
