In this article we will discuss about the process of oxidation of fatty acids. Oxidation of Even-Carbon, Saturated Straight Chained Fatty Acids: A. Activation of Fatty Acids: Before they are oxidized, fatty acids must be activated. This activation requires energy (supplied by ATP) and takes place in 2 steps, as may be seen in figure 5-10. In a first step, [...]
Although substantial progress was made during the last decade, all replication mechanisms in eucaryotes are not yet understood because: (a) Replication is an event which occurs much more rarely than in bacteria. Initiation of replication is therefore highly controlled; this complicates the understanding of this process; (b) The DNA is not naked, in the cell, but in the form of [...]
In this article we will discuss about the classification of lipids. Contrary to carbohydrates which constitute a family of relatively homogenous compounds, lipids form a very heterogenous class of compounds of widely differing structures and grouped according to their insolubility in water and solubility in organic solvents (ether, acetone, chloroform-alcohol mixtures, etc.). These solubility criteria are not absolute. Lipids were [...]
