Alkynen

Een alkyn is een koolwaterstof met tenminste één driedubbele binding tussen een koolstof en een andere verbonden koolstof. 


Acyclische formule: Cn H(2n - 2) 
Cyclische formule: Cn H(2n - 4)


Bij naamgeving wordt aan de -yn uitgang een zo laag mogelijk nummer toegekend.Substituenten uiteraard zo klein mogelijk.

Alkynen: Elektrofiele additie

Elektrofiele additie: Waterstofhaliden op alkynen Voorbeeld van waterstofhaliden: HCl, HBr, HF, HI Gebruik van één equivalent waterstofhalide met alkyn (dus 1:1 geen overmaat geen tekort) Bij een overmaat aan het waterstofhalide zal een tweede reactie plaatsvinden op het gehalogeneerde alkyn, ter vorming van een geminaal regioisomeer.

Coca-Cola: Life - myth or truth?

"Coca-Cola Life" Recently the Coca-Cola company released a new beverage: the Coca-Cola Life drink. It should contain less sugar than the normal Coca-Cola drink; a part of the sugar is replaced with the recently approved sweetener from the Stevia plant (stevioglycosides). It's being sold as a 'natural' drink, but those stevioglycosides are as natural as the chemical sweetener aspartame found in Light and Zero drinks. However it is true that the amount of sugar is much lower (being reported as 33%, some say it's around 20%); yet approximately still 3-4 sugar cubes / 33 cl can (5-6 in a normal can). I bought it myself and found that the flavor has not really changed from the original Coca-Cola, however it does taste more "flat" - but definitely true it yourself. The outside of the can has the colour green. I personally do not associate this "healthy - natural" colour with Coca-Cola, but it's growing on me. In sum...

Basic structure of a virus

Very basic explanation of a virus: Virus consists of a  - Head - Tail - Legs/Fibres The head contains the DNA/RNA, nucleic acids (genetic material, GM). It depends on what kind of virus we speak of, there are a lot of different kind of viruses. It is protected from the outside with a protein coat, that consists of hemagglutinin and neuraminidases, hence names given for viruses (f.e. H1N1, Influenza virus). The tail connects the head with the legs/fibres. Those legs will make sure the virus can bind on its host, for example a bacterial cell or a human cell. Viruses that bind on bacteria are often called bacteriophages. When connected to a host, the virus will inject its DNA/RNA into the cell via the tail. Once its GM is injected, the virus will normally eject from the cell and fall apart/gets secreted out of the organism. The GM will be implemented into the hosts genome often via reverse transciptases. Now this GM will code for proteins that induce transcription of th...
