for measuring and comparing relative molecular flux rates of different biological molecules by administering isotope-labeled water to one or more tissues or individuals and comparing the molecular flux rates of two or more biological molecules, including biological molecules in different chemical classes. ...
Explain why in gaseous reaction the collision frequency between molecules is far greater than the rate at which molecules react. Compare and contrast the ease with which molecules are able to move relative to each other in the three states of matter. ...
SNARE proteins – small protein molecules that reside in theplasma membraneand vesicle membrane − are responsible for the fusion process itself. Whenever the membranes approach each other, the proteins stack on top of each other, twisting together like ropes in the direction of the membrane (Fig...
Compare and contrast glycogen and fat as energy storage molecules. How does the chemical structure of carbohydrates and cellulose (or fiber) differ? How do we benefit from each of these molecules? How do they impact our health and ability to function? How does our body process these molecules...
diffusible molecules called autoinducers. When the cell population reaches a critical threshold (a quorum), these autoinducers initiate a cascade of reactions that activate genes associated with cellular functions that are beneficial only when the population reaches a critical density. For example, in ...
Molecules are 3-dimensional (3D) structures so it is alwaysmore accurateto describe them in 3D. Representations of organic molecules in 2D, such as fully displayed formulae, are often used for speed and simplicity. While they show the atoms in the molecule and the connections between them, o...
¿What do I see in common in mor than 3 molecules? All of them have a functional group ester. All of them have double bond. All of them have oxygen atoms with two pair of electron unpaired each. I think that it can be volatile by nature of the double bond. ...
Hexanenitrile Propyl Pentanoate Compare the above with the equivalent semi-displayed formulae (= 'simplified displayed formulae') below: ... and with the following fully displayed formulae: See alsohow to draw organic molecules. In the News:...
In immunohistochemistry (IHC), on the other hand, the presence of proteins or molecules is examined in a tissue-specific context. Here, ultrathin sections of organ preparations (usually embedded in paraffin wax) are used to e.g. investigate the expression of proteins in a healthy organ compare...
What are the differences between organic and inorganic substances/molecules? Compare and contrast pepsin and trypsin. HIV is a retrovirus. Describe how a retrovirus is different from other viruses. What are the functions of mRNA, tRNA, and rRNA? How are the three muscle types alike in structure...
