Which of the following is NOT an organic compound found in urine?

Chloride is considered an inorganic compound and is typically found in the form of ions, such as sodium chloride (table salt) in urine. In contrast, urea, creatinine, and uric acid are all organic compounds, derived from metabolic processes in the body.

Urea is a major nitrogenous waste product formed from the breakdown of proteins, creatinine is produced from muscle metabolism, and uric acid is a byproduct of purine metabolism. These compounds contain carbon and are classified as organic due to their molecular structure, which includes carbon-based backbones. Chloride, lacking this characteristic, is classified as an inorganic compound. This distinction is key when analyzing the composition of urine and understanding the types of substances present.
