Aspartate + a- keto acid >> Oxaloacetate + a amino acid
This reaction is occur because the a- keto acid in the equation can come from any amino acid, the 15 N from aspartate is rapidly transferred to other amino acids.
15N is symbol use as the isotope of nitrogen with mass number 15. comprises of 0.4 % of stable nitrogen found, so the relative abundance of each in amino acid is simply a reflection of how much is found in nature in general.
This isotopes is enrichment of the labelled amino acids was determined following a previously developed procedure comprising by determination of the spectral purity of the selected natural abundance amino acids.

Earths elliptical orbit around the sun with winter occurring when the earth is far away from the sun and summer is closest to it how ever our planets distance from the sun has a little effect on the onset of seasons
hope this makes sense if not just message me and ill try to put it in a more understanding way :)
phospholipids, ....the absorption of small particles<span> by a </span><span>STATIONARY cell

Is this a question lol I'm kinda confused
It forms<span> in lagoons where ocean waters high in calcium and sulfate content </span>can<span>slowly evaporate and be regularly replenished with new sources of water. The result is the accumulation of large beds of sedimentary </span>gypsum<span>. </span>Gypsum<span> is </span>commonly<span>associated with rock salt and sulfur deposits.</span>
