Amino acid metabolismUniversity of Waterloo
The degradative pathways can be divided into two major classes. As shown here most amino acids are converted to intermediates of the citric acid cycle or to pyruvate which in turn can serve as precursors for gluconeogenesis these are the glucogenic amino acids. Those amino acids that yield acetoacetate are called ketogenic since acetoacetate is one of the ketone bodies (see slide 10.4). Compare Products Select up to 4 products. Summary The protein encoded by this gene is a membrane transporter that mediates urea transport in erythrocytes. This gene forms the basis for the Kidd blood group system. provided by RefSeq Mar 2009 Allophanic acid amide
