(1) Chain Length Will definitely affect melting point, as this website explains pretty well: "Melting point principle: as the molecular weight increases, the melting point increases." (2) Number of Methylene groups. This is another way of describing unsaturated from saturated fats. The more saturated a fat is, the straighter it is. Methylene ...

The smell of dry erase markers come from the chemicals ethanol, butanol and isopropyl alcohol. Like all chemicals inhaled through the nose, they bind to the Receptor neurons in the located in the back of the nose. The neurons interpret the chemicals using a 'lock-and-key' model but the specific way its coded and perceived in humans is still being researched ...

As the concentration of sugars in the sap increases, so does viscosity. At high viscosity, the sap will not flow at a sufficient rate to provide nourishment to the different plant tissues. In addition, there are limitations to concentrating the solutes in the sap. As the sap becomes more concentrated, the plant would be working against a osmotic gradient to ...

Doxycyline inhibits iNOS and TNF-alpha expression. It also influences secretion of IL-1beta, IL-8, and TNF-alpha, as well as other inflammatory cytokines. [These are results collected from multiple systems.] For appropriate references, see: Leite et al (2011). Anti-inflammatory properties of Doxycycline and Minocycline in experimental models: an in vivo ...
