Why does osmosis not cause submerged water plants to swell up and burst? How can you tell when the pressures have equalized? How does the process of fermentation sterilize water? How do glycerol, antifreeze, and various concentrations of NaCl affect freezing point?
If the plant did not remove oil and grease during pretreatment, it will do so during primary treatment by skimming these fats from the surface. Some plants add alkali substances to the skimmed fats in a process known as saponification. Doing so is the first step in producingsoaps and glycero...
How does polyacrylamide gel electrophoresis (PAGE) work? The basic principle of PAGE is to separate analytes by passing them through the pores of a polyacrylamide gel using an electric current. To achieve this, an acrylamide–bisacrylamide mix is polymerized (polyacry...
fat + NaOH ---> glycerol + sodium salt of fatty acid CH2-OOC-R - CH-OOC-R - CH2-OOC-R (fat) + 3 NaOH ( or KOH) both heated ---> CH2-OH -CH-OH - CH2-OH (glycerol) + 3 R-CO2-Na (soap) R=(CH2)14CH3 Jmol._Canvas2D (Jmol) "jmolApplet0"[x] --->spin on--->-...
Research has found that light-to-moderate alcohol intake does not cause weight gain. Instead, regular heavy drinking may lead to weight gain over time. The National Institute on Alcohol Abuse and Alcoholism (NIAAA) defines heavy drinking as more than three drinks per day or seven drinks per ...
Lipase breaks the fat into its parts: glycerol and fatty acids. These components are then reassembled into triglycerides for transport in the bloodstream. Muscle cells and fat (adipose) cells absorb the triglycerides either to store them or to burn them as fuel. You need to eat fat for ...
In this work, we show that finding and controlling optimum pH environments with Pt-based alloy catalysts can create high catalytic performances for electrocatalytic glycerol oxidation reaction (EGOR). Compared to a Pt/C catalyst, the PtCu/C alloy catalyst has higher reaction...
To make a normal fat, you take three fatty acids and bond them together with glycerol to form a triglyceride, like this: Since this particular triglyceride happens to contain three molecules of stearic acid, it is also known as tristearin. This diagram shows one fat molecule. When you eat ...
usually methanol (CH3OH) or ethanol (CH3CH2OH) in the presence of a catalyst such as potassium hydroxide (KOH) or sodium hydroxide (NaOH). When this happens, the triacylglycerol is transformed to form esters and glycerol. The esters that remain are what we then call biodiesel [source:PennStat...
Explain in detail why enzymes are stored in glycerol. What role do enzymes play in cell signaling? Why do enzymes have different optimal pH? How does cell signaling affect the response of enzyme activity? What are the main functions of an enzyme? What happens to an enzyme during a chemical...
