Explain ornithine cycle
WebApr 4, 2024 · Citric acid cycle, often referred to as “Krebs cycle” or “TCA cycle” is a mitochondrial metabolic cycle in which a (2C)acetyl unit from acetyl-S-CoA condenses with a (4C)oxaloacetate and generates a (6C)citrate molecule. An isomer of citrate is then decarboxylated, and the resulting (5C)a-Kgl undergoes oxidative decarboxylation to yield a WebCH 18. Normal human blood plasma contains all the amino acids required for the synthesis of body proteins, but not in equal concentrations. Alanine and glutamine are present in much higher concentrations than any other amino acids. Suggest why. Alanine and glutamine play special roles in the transport of amino groups from muscle and from other ...
