[Lao Tzu]

question. how does an amino acid get to a cell, and how does it get into a cell? active or passive transport.

 

[HappyScrappy]

both. neither.
I wanted to say passive, but I'm usually wrong.

pm macrophagealpha - he knows his shit on this sort of thing.

i enjoy that one too.



question 2. what is the difference between a '=' bond and a '-' bond. i.e., a carboxyl bond is (for lack of ability to draw)

O=C-OH

what does the O=C bond have that the C-OH doesn't?

 

[HappyScrappy]

what does the O=C bond have that the C-OH doesn't?

isn't that the stronger double bond?
where more electrons are shared due to avalability?

C-OH is in alkane series, which is a hydrocarbon group, only single covalent bonds are present.

C=OH is in the alkene series, also a hydrocarbon, they contain at least one double bond as well as single bonds.
