While quartz crystals take tens of thousands of years to grow in nature, you can grow crystals of sugar in only a few days! In the process, students learn about saturated and supersaturated solutions, seed crystals, and the rate of crystalline growth. In
For flavonoidO-glycosides, the sugar units and the free aglycone are obtained through a common fragmentation process. By analyzing them/zvalues of consecutive product ions formed afterO-glycosidic bonds breaking, the presence of hexoses and pentoses can be determined as [M-H-162] and [M-H-132...
We have been very busy here at Life At The Zoo.. but not always had the time to share our activities – such as this Growing Beans activity. We have lots of photos to share and will hopefully do so over the coming days and weeks. We have been particularly busy with Gardening with Ki...
Back then, we had such good weed that I would have put it up against anywhere in the world. The local strain was Willies One Hit Wonder Buds. It was truly dank. Dank enough for me to affectionately rename the city Danktown. It was light and dark green, coated with crystals and red ...
while the remaining aqueous phase contained the sugar. The sugar component was subsequently identified using Paper Chromatography on Whatman No.1 paper sheets from England, alongside standard sugars. For the development of the chromatogram, a solvent system comprising of n-butanol, acetic acid, and ...
During the experiment, the water potential was maintained at −10 kPa in control conditions (optimal soil moisture) and −30 kPa in conditions of water deficit. The need for irrigation of plants was determined on the basis of contact soil tensiometers placed in pots of individual experimental...
The abundance of druses/spherical calcium oxalate crystals present in the mesophyll cells, which are larger in diameter of 140–160 µm (Figure 3H). Chlorenchyma is differentiated into palisade parenchyma and shows the presence of secondary metabolites and an abundance presence of starch grains ...
