Study Notes
Protein Metabolism Waste Products
- Urea is the primary waste product of protein metabolism, formed in the liver from the breakdown of amino acids.
- Urea is excreted through urine, helping to eliminate excess nitrogen from the body.
Non-Protein Nitrogen (NPN) Compounds
- Ammonia is considered a waste product among NPN compounds, formed during the breakdown of proteins.
- Urea is commonly used to evaluate renal function, as its levels reflect kidney efficiency in filtering blood.
Assessing Renal and Liver Function
- Blood Urea Nitrogen (BUN) levels are a standard test to measure urea concentration, indicating renal function.
- Aminotransferases, specifically Alanine aminotransferase (ALT) and Aspartate aminotransferase (AST), are used to assess liver function alongside NPN evaluation.
Urea Molecular Details
- The molecular formula of urea is CO(NH2)2, signifying one carbon atom, one oxygen atom, and two amine groups.
