What's the difference between substituted and urea?

Substituted


Definition:

  • (imp. & p. p.) of Substitute
  • (a.) Exchanged; put in the place of another.

Definition:

  • (a.) A very soluble crystalline body which is the chief constituent of the urine in mammals and some other animals. It is also present in small quantity in blood, serous fluids, lymph, the liver, etc.
