Summary Introduction

To determine: The cleavage products of PIP2 by phospholipase C.

Introduction: Phosphatidylinositol 4,5-bisphosphate ( PIP2 ) is an essential lipid that is integral to the plasma membrane of the plant and animal cells. It works as a second messenger in a various signaling pathways and also involved in metabolic processes. PIP2 is an important phosphoinositide that makes about 1% of the cell membrane. PIP2 is also involved in the signaling transduction of the extracellular or intracellular components.

Summary Introduction

To compare: The DAG and IP3 with respect to their properties and solubilities in water.

Introduction: DAG and IP3 are the products of the hydrolysis of PIP2 by the enzyme phospholipase C. DAG pathway is a signaling transduction pathway that is involved in the activation of enzymes. IP3 molecule is the negatively charges polar molecule. IP3 involved in the signaling transduction of chemicals such as growth factors, hormones, and neurotransmitters.

Summary Introduction

To predict: Whether either would diffuse readily through the cytosol.

When was the dihydropyridine calcium channel blocker isradipine first patented and by whom? Please provide information on the origin and history of isradipine and who owns it/manufactures it.
9) Below, there is a representation of an SDS-PAGE gel. Assuming the samples in the MW standard have masses of: 66 kDa, 45 kDa, 36 kDa, 29 kDa, 24 kDa, 20.1 kDa, and 14.2 kDa, a) Figure 4: indicate where each of the measurements were taken and label as in II.6. figure 2 above. b) As in II.7. Table 1 above create Table 2 using the data below. Determine the r.f. values for the MW standards, plot the relative mobility versus the log of the mass for the standards, and use the best fit straight line to determine the molecular weights of the proteins in the whey, peak 1, and peak 2 lanes. (5 pts—this will be scaled up appropriately if your gel did not develop properly) dye MW Whey Peak 1 Peak 2
