In this topic we will discuss the relationship betwwen Organic chemistry and life applications that
we can notice and benifit....
Someone may ask about the importance of this relation?
and I answer-- If u know the importance and the benifit of what you study,you will never forget the basic science later...
.And Let's try with the first section of practical organic chemistry (Salts of carboxylic acids) Okay.. Let's start with Oxalic acid and its salts. What is the importance of it? How all the world now think about making foods with low content of Oxalic acids and why? Is it too serious that we should take care when we have foods with high amounts of Oxalic acids if some of us have problems with their kidney functions? Let's see then i want all Of you tell me what are the most important chemical tests you did in the lab. for the Oxalic acid and its salts to identify it?
The affinity of divalent ****l ions is sometimes reflected in their tendency to form insoluble precipitates. Thus in the body, oxalic acid also combines with ****ls ions such as Ca2+, Fe2+, and Mg2+ to deposit crystals of the corresponding oxalates, which irritate the gut and kidneys. Because it binds vital nutrients such as calcium, long-term consumption of foods high in oxalic acid can be problematic. Healthy individuals can safely consume such foods in moderation, but those with kidney disorders, gout, rheumatoid arthritis, or certain forms of chronic vulvar pain (vulvodynia) are typically advised to avoid foods high in oxalic acid or oxalates. The calcium oxalate precipitate (better known as kidney stones) obstruct the kidney tubules. Conversely, calcium supplements taken along with foods high in oxalic acid can cause calcium oxalate to precipitate out in the gut and drastically reduce the levels of oxalate absorbed by the body (by 97% in some cases.
Oxalic acid can also be produced by the ****bolism of ethylene glycol ("antifreeze"), glyoxylic acid or ascorbic acid (vitamin C). Under certain conditions of concentration and pH, oxalic acid can precipitate in the kidneys as calcium oxalate crystals, forming an estimated 80% of kidney stones
Some Aspergillus species produce oxalic acid, which reacts with blood or tissue calcium to precipitate calcium oxalate. There is some preliminary evidence that the administration of probiotics can affect oxalic acid excretion rates
NOTE :- the deadline of your answers for the 1st sample = Oxalic acids is after 24 hours
There are 3 prizes for 3 of you for each section and this depend on the amount of your participations for all samples i ask about, And the accuray of the test steps procedure....Tell your friends and Quick to answer
Thanks alot ....Ahmed Elkamhawy
