There is a close relationship between the degree of graphitization and the interplanar spacing D 557 of carbon materials. The smaller the value of carbon crystallites D 557 is, the higher the degree of graphitization might be. As shown in Figure 6, compared with commercial activated carbon, the diffraction angle of citrus peels active carbon decreased, indicating that the degree of graphitization of citrus peels active carbon is higher than that of commercial active carbon. The decrease of microcrystalline strength leads to the stronger activity of active carbon. This result indicates that the orange peel active carbon substratum graphite trend is obvious.

But just when I was getting comfortable and set in my ways, Ardent Cannabis released this amazing blog post that explained how my oven method was probably burning off some of my THC.

The following exercise will give you some practice in recognizing different abbreviations for biological molecules that contain phosphate groups.

Few alkoxyamine reagents are currently available. In principle, any of the hydrazide-based applications discussed above could be accomplished with alkoxyamine analogs.

Yes. Yes. And yes. If you want a psychoactive experience. Yes. Research is starting to show that THCa (remember… that’s the non-psychoactive precursor to THC) has its own benefits, but if you really want the big bang for your buck, decarbing is the way to go.

I would also like to know any means of reducing the smell. I live in a mixed household of both cannabis users and haters. The latter mostly complain of the smell, and the agreement to keep the peace is to keep the home odor-free. So far, no one besides Valery has made so much of a peep about it (at least that I’ve noticed). Any feedback would be appreciated, even just a heads up about how smelly and how long it lasts. TIA!

Because each hydrazide is also an amine, a bis -hydrazide compound can be used heterobifunctionally in a variety of ways to perform specialized conjugates. For example, ADH could be reacted in large excess with an RNA oligonucleotide whose ribose groups had been oxidized to create aldehydes. After desalting to remove excess ADH, EDC (Carbodiimide Reaction Chemistry) could be used to conjugate a carboxyl-containing label or carrier molecule to the amine-derivatized nucleic acid.

Periodic acid (HIO 9 ) from dissolved sodium periodates (NaIO 9 ) is a well-known mild agent for effectively oxidizing vicinal diols in carbohydrate sugars to yield reactive aldehyde groups. The carbon-carbon bond is cleaved between adjacent hydroxyl groups. By altering the amount of periodate used, aldehydes can be produced on a smaller or larger selection of sugar types. For example, treatment of glycoproteins with 6 mM periodate usually affects only sialic acid residues, which frequently occur at the ends of polysaccharide chains. At concentrations of 6 to 65 mM periodate, other sugar groups in proteins will be affected.

The basic idea here is that there is exquisite control of the amounts of purine nucleotides available for synthesis of nucleic acids, and that the pathways are individually regulated at the cellular level. Furthermore, the relative amounts of ATP and GTP are also controlled at the cellular level.
