Glycocalyx

Postby gqh » Sat May 12, 2012 8:27 am

Glycocalyx is only found in the extracellular matrix of cells attaching to the proteins or lipids of a plasma membrane, right?
however, out of curiosity, may I know why it isn't found in the intracellular cytoplasm of a cell? If the bonds meet its conditions' requirement, definitely, it'll form, right? So, wat difference in condition that does not permit glycocalyx to be formed intracellularly?

probably presence of enzymes and its substrates

Cis or trans? That's what matters.

I'm an AS-lvl student here, I received a question from my text book, it says "Why is glycocalyx only found on the extracellular of the cell surface membrane?"

should I answer it like:
cause glycocalyx can't be formed on the intracellular cell surface membrane due to the absence of some enzymes or substrate?
or
glycocalyx attached on the outer part of the membrane due to the requirement for cell to cell recognition function and some other functions which is of no use if glycocalyx is attached intracellularly.
or
some other better answers? (any suggestions)

btw, just realize, are there any glycocalyx formed on the organelles' plasma membrane? Organelles are also found in the cell and don't they require organelle recognition(or does this recognition ever exist)?
