  • Allantoin - Uric acid oxidises to produce allantoin. It is an excretory substance found in amniote embryos. Hippuric acid is only detected in excretory products when benzoic acid is consumed. Hippuric acid -  is created when it interacts with glycine.

  • Amino acids - Invertebrates like Unio, Lymnaea, and Asterias contains amino acids. These creatures are known as amionotelic.
