Monster VS Alien

Monster VS Aliens



"Jelly Bob" seem like very love jelly and hope it be his girlfriend




Do you watch monster VS Alien???

Inside this show, there are 3 main characters; the either one is in blue color. Some of my friend said that the one is snot, but I think that is a jelly lah!!!(heheh^^) So i called it as "jelly bob".

As u saw that in monster VS alien, the “jelly bob” can move around and when it step on by a monster it still can re-shape back the original shape. So, let us back to our real life, of course a jelly can’t walk and can’t be so powerful, but to make jelly into a shape, a thickening agent is needed. If without thickening agent, jelly will collapse and not firm. Normally, pectin is use as thickening agent in jelly.

Pectin has a complex structure with a linear chain of α-(1-4)-linked D-galacturonic acid polysaccharide backbone, hologalacturonan. The structure of pectin consists of homopolymeric in majority and partially methylated poly-α-(1→4)-D-galacturonic acid residues.


At the same time, the region of galacturonic acid can be replace by α-(1→2)-L-rhamnosly-α-(1→4)-D-galacturonosyl, and the side chain of neutral sugar will branch off. Besides that, pectin also have a structure type called rhamnogalacturonan II, which is a less frequent complex. This type of side chain can be containing other residues such as L-fucose, D-xylose, D-apiose, 3-deoxy-D-lyxo-2-heptulosonic and so on so forth.




Pectin can be found in some fruits like apples, oranges, strawberries, plums and so on. The approximately levels of pectin in fruit or plant can be calculated:

Apple – 1-1.5%
Cherries – 0.4%
Orange – 0.5-3.5%
Carrot – 1.4%


To extract pectin from fruit or plant, some steps can be taking on:

1. Add and immerse hot diluted acid that around pH 1.5-3.5 to the plant and wait for several hours for extraction.
2. When the protopection of plant loses some branching because of bond breaking, the chain length will mix with the solution.
3. Filtered the solution then concentrate the filtrate in vacuum.
4. Then, the filtrate will precipitated by adding ethanol or isopropanol.
5. Separate alcohol-precipitated pectin and dry it.


Do you still remember the “jelly bob” inside the show is blue in color???



Now, to dye a jelly into different kind of color, some coloring agents are needed. As known that different types of chemical or compound use will produce different color. The table below show different types of chemical compound and the color:



So for blue colour, Indigo carmine and brilliant blue FCF are use. For Indigo carmine, it will cause for some allergic, thus not much of product will use this chemical. Therefore, let us discuss about brilliant blue FCF.

Brilliant blue CFC, under commercial names is known as colorant. It is denoted by E number E113 and has a colour index of 42090. In addition, it is a synthetic dye derived from coal tar. Brilliant Blue FCF is described as the sodium salts.

It consists essentially of disodium alpha-(4-(N-ethyl-3-sulfonatobenzylamino) phenyl)-alpha-(4-N-ethyl-3-sulfonatobenzylamino, cyclohexa-2,5-dienylidene) toluene-2-sulfonate and also together woth sodium chloride or sodium sulphate as the principle uncoloured components. Sometimes, calcium and potassium salts are also permitted. Besides, it can also appear as an aluminium lake.

The chemical formation of Brilliant blue FCF is C37H34N2Na2O9S3




Although in our life we saw that a lot of things especially food, that are colourful and very beautiful, but colouring agent actually is not healthy to our body. Some artificial colouring agent will also cause some allergic, asthma and others side effects. Therefore, for our health, we need to be aware to our surrounding lure!!!

Just like the show, the 3 characters try their best to protect their country from attack of alien. We will act as a defender to stop off any alien “bacteria” and “bad things” enter our body and protect our body.

Now H1N1 quite serious in Malaysia and also in the whole world, take care yourself!!!
