Nice, I teach Chemistry to high school students

  1. They also do not 'pack' as readily and hence have a lower melting point. When incorperated into a cell membrane this means the membrane is less rigid and therefor less prone to damage.

I also remember when chemistry was fun :'(

The answer to that #1 question is vast.
In one way they are preferred because of their anti knock properties. And they don't get used up as fast as straight chain

Cant even remember wat i was taught yesterday.

I couldn't remember up to 5 of those questions ... Jamb chemistry no be beans though .
