Question

Excess of amino acids in the body is breakdown to urea

Answer 1

Ahoy.

Ammonia is formed by oxidative deamination.
Ammonia helps in production of urea in liver.
Check out the urea cycle that I made..!!
Enjoy! :))

Answer 2

Hey there

Urea is formed in the liver by two chemical processes as follow -

1 ) De-amination:-

• Aka Oxidative delamination

Aka Oxidative delamination • During this reacn AA is converted into its corresponding Keto acid by the removal of amine functional group as ammonia

Aka Oxidative delamination • During this reacn AA is converted into its corresponding Keto acid by the removal of amine functional group as ammonia •This ammonia ammonia eventually goes into the urea cycle

2 ) Urea cycle / Ornithine cycle:-

It is the process of formation of urea which takes place in the liver

All the steps of cycle are enzymatic and can be visualised as -

• Step 1:- It involves the formation of carbamyl phosphate from ammonia and Co2 in the presence of enzyme carbamyl phosphate synthetase and 2 ATP

•Steps 2:- It involves , the formation of citruline by the combination of carbamyl Phosphate and Ornithine in the presence of enzyme Ornithine carbamyl transferase

•Steps 3 :- citrulline joins with the aspartic acid with the help of argino succinate synthetase to form argino succiinic acid in the presence of an ATP

•step 4 :- Argino succinic acid breaks into fumaric acid and Arginine with the help of arginosuccinate

•Step 5 :- Arginine is then hydrolysed in the presence of arginase to form Urea and Ornithine
