ammonia (NH3‚ Mr ϭ 17)‚ and carbon dioxide (CO2‚ Mr ϭ 44). But‚ unlike water‚ none of these latter molecules contains hydrogen bonds. In gases‚ molecules are widely spaced and free to move about independently. In liquids‚ molecules are closer together. The observation that water is liquid under conditions when similar molecular substances are gases provides evidence that in water it is hydrogen bonds that pull the molecules very close to each other. As a result‚ at the temperatures and pressures

Case Study: Newsflash! Transport Proteins on Strike! 1. What is the meaning behind the PHOSPHOLIPIDS’ chant? Phospholipids make up most of the cell membrane‚ in a phospholipid bilayer. Phospholipid molecules form two layers‚ with the hydrophilic (water loving) head facing the extracellular fluid and the cytosol (intracellular) fluid‚ and the hydrophobic (not water loving) tails facing one another. The cell membrane is constructed in such a way that it is semipermeable‚ and allows oxygen

CHARACTERIZATION OF PROTEINS Abstract Different techniques and principles for protein extraction and characterization were demonstrated in this experiment. Various proteins were extracted from different sources: 1.67 g yeast invertase‚ 1.03 g egg white albumin‚ and 5.15 g of milk casein. Activity assay for invertase was performed using Benedict’s test and the enzymes inverting action on sucrose was confirmed. Warburg-Christian Method and Bradford Assay were also employed to determine the protein concentration
