conclusion is that the higher salt concentration in the solution the greater the decrease in mass of the potato will be‚ the graph I have drawn supports my conclusion. The 10% salt concentration shows that on average the potato loses 2.6% of its overall mass. 20% salt concentration shows a further decrease in mass this time it is an average of 13% overall mass decrease. 30% salt concentration shows an average decrease of 18.8% in overall mass. The 0% salt concentration actually shows a mass increase

Characterization of Saponifiable Lipids and Characterization & Isolation of Complex Lipids Jan Kevin Roxas‚ Nashiba Samad‚ Erickson Santos Department of Chemistry‚ University of Santo Tomas‚ Manila‚ Philippines Abstract Lipids building blocks of different organic material that are water insoluble. This can be divided into simple and complex lipids that have several forms like waxes‚ triacylglycerols‚ phosphoacylgylcerols‚ sphingolipids‚ eicosanoids‚ isoprenoids and many other. To identify‚

Fats‚ waxes‚ monoglycerides‚ and triglycerides are all types of lipids. Triglycerides are a main form of energy for both plants and animals. Triglycerides are broken down into 3 fatty acid chains. Each fatty acid chain is further broken down into multiple groups of Acetyl CoA. Acetyl CoA molecules go through the citric acid cycle and the electron transport chain. 12 ATP are formed from each Acetyl CoA molecule. Carbon chains that are saturated with hydrogen atoms Chains are straight and

The neurotransmitter then diffuses across the synapse and binds to a receptor that would initiate the signal transmitted. 2. Explain the effect of the following on the membrane potential: a. Open sodium gated ion channels Open sodium gate ion channels result to entry of more sodium ions into the intracellular membrane and therefore would lead to a more positive membrane potential. This

Lipid Digestion The process of mastication is our only conscious act in the digestion of the foods we consume. After that‚ it’s out of sight‚ out of mind; but should it be? What does it take to transform that last swallow into the energy our body needs to sustain itself? In the case of lipid digestion‚ the real magic occurs throughout the gastrointestinal tract with a synergistic collaboration from the accessory organs: the liver‚ gallbladder and pancreas. Understanding the whole process of digestion
