Glycoprotein-
A polysaccharide chain attached to a protein on the cell membrane( phospholipid
bilayer). They act as receptors in cell signaling.
Cell signaling- Communication between cells.
Glycoprotein works as a receptor by;
allowing cells to work together through he…

Emulsion test- for lipids
add ethanol and shake for approximately 1 minute.
if it goes cloudy/milk lipids present
No lipids and it stays clear.

Reducing sugars test-Benedicts solution( mono and some disaccharides)
-Add excess benedics solution
-Heat but don't…

Hydrophilic and hydrophobic interaction- hydrophobic amino acids go in the center
and hydrophilic amino acids go to the outside.
R groups can determine the tertiary structure of protein because the r group could
be either hydrophobic or hydrophilic, have…
