Which amino acids can be deaminated? Three amino acids can be deaminated directly: glutamate (catalysed by glutamate dehydrogenase), glycine (catalysed by glycine oxidase) and serine (catalysed by serine dehydrogenase). What 2 monomers must be deaminated? Amino acids must be deaminated before entering any of the pathways of glucose catabolism: theRead More →

Supplemental amino acids are used for pharmacological rather than nutritional purposes. What are theRead More →
Ornithine is a free amino acid that is not encoded by DNA but synthesized through the urea cycle from arginine. Is ornithine a small amino acid? 2.2 Ornithine-derived alkaloids Ornithine itself is a non-protein amino acid formed mainly from L-glumate in plants, and synthesized from the urea cycle in animalsRead More →

Carbohydrates are used by the body for energy and structural support in cell walls of plants and exoskeletons of insects and crustaceans. They are made of smaller subunits called monosaccharides. Monosaccharides have carbon, hydrogen, and oxygen in a 1:2:1 ratio. What is the chain of subunits called? Most macromolecules areRead More →
Three of the most commonly mentioned risks of long-term amino acid supplementation are nausea, headache, and pain. Amino acid supplements can impact your blood sugar levels.
