    Study Notes

    Nitrogen Metabolism

    • The urea cycle, also known as the ornithine cycle, is the process that involves the conversion of ammonium ion to urea in most mammals.

    Amino Acid Fate

    • Excess amino acids in the body are deaminated, resulting in the removal of their amino group (-NH2) and subsequent conversion into carbohydrates or fats.
    • Surplus amino acids are utilized in the body by being broken down into carbon skeletons, which can be used for energy production or stored as glycogen or fat.

    Nitrogen Fate

    • The primary fate of the nitrogen in amino acids is excretion in the form of urea, which is produced in the liver through the urea cycle.

    Protein Degradation

    • The process of ubiquitination involves the labeling of proteins with ubiquitin, marking them for degradation by the proteasome.
