Dictionary » A » Aspartate



(Science: amino acid) a nonessential amino acid that plays a critical part of the enzyme in the liver that transfers nitrogen-containing amino groups, either in building new proteins and amino acids or in breaking down proteins and amino acids for energy and detoxifying the nitrogen in the form of urea.

Depleted levels of aspartic acid may occur temporarily within certain tissues under stress, but, because the body is able to make its own aspartic acid to replace any depletion, deficiency states do not occur.

Aspartic acid is abundant in plants, especially in sprouting seeds. In protein, it exists mainly in the form of its amide, asparagine.

The popular sweetener Aspartame is a combination of aspartic acid and phenylalanine. Aspartic acid is considered nontoxic. A type of amino acid, also referred to as aspartic acid.

HPLC amino acids standard

you mean like whether to pick aspartate or lysine? In such a case you must of course take all of them, because each should have different behavior. Of course the separation depends on your colony and conditions

Re: Generation of DNA nucleotides

... biochemical reaction with many steps. And yes, each step has a specific enzyme that takes a basic starting molecule (like the amino acid aspartate) and modifies it in steps, till it is a nucleotide (a nitrogenous base attached to a deoxyribose sugar, which is then phosphorylated three ...

Photosynthesis Trivia

... plants in cool, moist climates. 4. C-3 photosynthesis is more recent on an evolutionary scale than C-4 or CAM photosynthesis. 5. Oxaloacetate and aspartate are compounds in the C-4 cycle of photosynthesis. 6. Oxaloacetate differs from RDP in that oxaloacetate is a four carbon compound. 7. CAM ...

Re: Polar or non-polar: Conflicting answers

Dredging up old threads, I see. The side chain of Tyrosine is polar. But polarity is a relative thing. Certainly, compared to an ionized Aspartate or Glutamate, it is relatively non-polar, but compared to an Alanine or Leucine, it is polar. The phenolic OH can be fully ionized (though it’s ...

Denaturing Enzymes

... too much H+, it would interupt this interaction by binding to a negatively or slightly negative charged amino acid sidechain, eg. histidine, aspartate, glutamate. In other word, I think I'll consider it as fully protonated. DIsruption in 3D structure of enzyme would denature it, because the ...
