define transport and uptake of zinc by cellsafter absorption zinc is bound to albumin and transported to the liver in liver it is concentrated and
determine factors affecting zn absorption - micro mineralsin the last unit you have studied that absorption of various minerals bioavailability is
define absorption of zinc - micro mineralslike iron zinc also needs to be liberated from food prior to absorption during digestive process proteases
explain the metabolism - zinczinc has been found to play an important biological role in our body zinc ions can be chelated and precipitated by a
determine food sources of zinczinc is normally associated with the protein andor nucleic acid fraction of foods thus foods high in proteins are good
define the importance of zinc in humanszinc deficiency in humans was reported by as prasad among people consuming mostly breads and very little
define assessment of iron status - haemoglobin and haematocritin the final stages of iron deficiency anaemia occurs haemoglobin and haematocrit
explain assessment of iron status - transferrin saturationtransferrin saturation as iron deficiency progresses there is a decline in transferrin
explain assessment of iron status - transferrin receptorstransferrin receptors as iron deficiency progresses into second stage the number of
explain assessment of iron status - serum ferritinserum ferritin this method is indicative of iron stores as we know a long term negative iron
explain assessment of iron statusin view of widespread iron deficiency it is important to have reliable and sensitive measures of iron status iron
what is iron overload and toxicitywe have seen that absorption of iron is very effectively regulated this prevents overload of the tissues with iron
define prevention of iron deficiencyiron deficiency anaemia accounts for approximately one-half or more of all the anaemias seen worldwide iron
why iron is required as a part of haemoglobinas a part of haemoglobin iron is required for the transport of oxygen to all cells in the body thus
define function of the iron uptake by cellsiron has several vital functions in the body it serves as a carrier of oxygen to the tissues from the
explain iron uptake by cellsiron participates in a large number of biochemical reactions however for iron to perform any function it first needs to
define excretion of iron in human bodyour body has a limited capacity to excrete iron once it has been absorbed daily losses in adult man are between
define transport and storage of ironyou have seen that transferrin binds both newly absorbed iron and iron released after degradation of haemoglobin
explain iron balance and regulation of iron absorptionthe body has three unique mechanisms for maintaining iron balance the first is the continuous
define inhibitors and enhancers - absorption of dietary ironphytates and fibre from whole grain cereals tannins and polyphenols in tea oxalates in
define solubility affecting absorption of dietary ironsolubility is crucial for non-haem iron absorption as the inorganic iron salts have to be
define iron factors affecting absorption of dietary ironwe have read earlier that iron in foods occurs either as haem or non-haem iron haem iron
define factors affecting absorption of dietary ironthere are mainly four factors that determine iron bioavailability absorption from the diet these
define absorption of dietary ironhaem iron is more bioavailable than non-haem iron because it is absorbed intact as a soluble complex by endocytosis
explain mechanism of absorption of haem ironhaem iron is soluble in the alkaline environment of the intestine it binds to the receptor on the
