Chapter 17 (part 2) - Protein turnover and amino acid catabolism. In this chapter you will: Know the essential and non-essential amino acids, know how dietary proteins are degraded to amino acids, know in which tissue type different processes occur, know that cellular proteins have different half lives. Know how this relates to there function,. | Chapter 17 (part 2) Protein Turnover and Amino Acid Catabolism Dietary Protein Turnover Protein Turnover Rates Vary Ubiquitin Related Protein Degradation Protein Ubiquitination Multiple Ubiquitins can be polymerized to each other. What determines whether a protein will become ubiquinated? Ubiquitinated Proteins are Degraded by the 26S Proteosome 26S Proteosome Removal of nitrogen transaminase deaminase Mechanisms to get rid of Ammonia Urea Uric Acid Urea Cycle Urea Cycle Step 1: Formation of Carbamoyl Phosphate Step 2: Ornithine Transcarbamyolase Step 3: Argininosuccinate Synthetase Step 4: Argininosuccinase Cytosolic enzyme Step 5: Arginase Urea Cycle Glucose-Alanine Cycle Catabolism of Carbon Chains From Amino Acids | Chapter 17 (part 2) Protein Turnover and Amino Acid Catabolism Dietary Protein Turnover Protein Turnover Rates Vary Ubiquitin Related Protein Degradation Protein Ubiquitination Multiple Ubiquitins can be polymerized to each other.
