This amphophilic nature of lipids essentially allows them to be able to form structures such as liposome’s, vesicles or membranes when subjected to aqueous environments. The biological lipids mainly originate from two major build-blocks or biochemical sub-units: isoprene and ketoacyl groups. Another distinct characteristic of lipids ...

What is an alkane? Any hydrocarbon which has only single bonds is an alkane and because these

hydrocarbons have a hydrogen in all possible locations they are called saturated and thus they
have this general formula, CnH2n+2.

But an alkyne is an unsaturated hydrocarbon which has at least one carbon-carbon triple bond

without any other functional groups thus they have given general formula of CnH2n-2.

Cis-trans isomerism is a type of stereoisomerism in which the position of the functional groups

differs, also known as geometric isomerism. The different is the orientation of the functional
groups as we know in cis isomerism the both functional groups are on the same side though in

It is hard to imagine a modern life without polymers. They are literally everywhere. What makes them so useful and unique? Chemists look inside the structure of a matter in order to explain specific chemical or physical properties. Polymers do have unusual structures. Their large molecules consist of particular segments that are repeated by some pattern. The segments are called monomers. As a result of polymerization, monomers completely change their properties. For example, polyethylene (-CH2-CH2-)n, “the largest tonnage plastic material”, is a waxy solid polymer (Nicholson 6). However, ethylene by itself is a gaseous matter.
Even though man-made polymers were introduced relatively ...

Sensors detect an input event and control an output event. The output often requires different timing than that of the input event. Sometimes several inputs must jointly produce an output event. In other words, logic alters the raw sensor signal so that it is directly useful for controlling local action in response to sensed events (Ouzounov et al., 2006). A sensor is an interactive application; it expresses interest in an event by defining a sensitive ‘region' and an event type. For example, if a sensor wishes to receive events directed to a geographical object, it can define its region ...
