Identifying Organic Compounds Problem: Based on the color of the indicator‚ which type of organic compound will be found in each type of food? Hypothesis: If Benedict solution is added to honey‚ then it will turn. If Biuret solution is added to egg whites‚ then it will turn. If Benedict solution is added to corn oil‚ then it will turn. If Benedict solution is added to glucose‚ then it will turn. If Benedict solution is added to gelatin‚ then it will turn. If Benedict solution is added to butter

producing another action potential (Stillman‚ 2005). In this lab‚ compound action potentials (CAPs) will be measured from an isolated sciatic nerve from a cane toad‚ Bufo marinus. Compound action potentials are the total sum of action potentials from the multitude of neurons that compose a nerve (Stillman‚ 2005).

The primary objective of this experiment is to determine the stress that various alcohols have on biological membranes. Membranes within cells are composed mainly of lipids and proteins and often serve to help maintain order within a cell by containing cellular materials. Different membranes have a variety of specific functions. One type of membrane-bound vacuole found in plant cells‚ the tonoplast‚ is quite large and usually contains water. In beet plants‚ this membrane-bound vacuole also contains

Bio-Rad Protein Assay INTRODUCTION Proteins are large complex organic macromolecules which are utilized for many important roles in the body. Proteins function in structure‚ transport‚ energy conversions‚ and play an important role in defense against diseases. Protein is also important for muscle recovery‚ which is why it is commonly associated with fitness. Though your body will always absorb 1g of protein the same way every time‚ protein companies like to make their product competitive

Identification of a Copper Compound by Percent Mass Unknown Compound: #9 Abstract: The objective of this experiment was to identify the unknown pure copper salt compound of #9. To do this‚ the mass of copper in the unknown was calculated and then divided by the mass of the whole compound to get the percent copper. The molecular weight was also calculated by dividing mass of copper compound used by moles of compound in unknown sample. The percent copper averaged out to 31.6% while the molecular
