Nucleotide Metabolism | Pyrimidine Biosynthesis (UTP & CTP)

The video tutorial covers the synthesis of UTP and CTP, highlighting the regulatory enzymes involved in different organisms, such as E. Coli and humans. It explains the differences between pyrimidine and purine synthesis, focusing on the separate formation of the pyrimidine ring. The tutorial details the enzymatic pathway, including the conversion of orotate to UMP and UTP, and discusses the energy requirements for CTP synthesis. The importance of these processes for organisms is emphasized, with a note on thymidine synthesis to be covered in a separate video.
