Protein which is likely to be seen within transmembrane of a cell membrane is:
a.A stretch of hydrophobic amino acids
b.A disulphide loop
c.A stretch of hydrophilic amino acids
d.Alternating hydrophilic and hydrophobic amino acids
A Group of amino acids are observed within transmembrance for communication form outside the cell to the cytoplasm.
Inner membrance proteins usally extend through the membrance numerous times and have stretches which are in the cytoplasm
and the peiplasm.
The stretches that travel across the membrance have usally uncharged,non polar (hydrophobic) amino
acids which make them more
soluble in the membranes
Lipids constitute the stretches and therefore ,they are very ydrophobic.
