Document Summary

Sugars are very important because it is used to metabolize atp. Certain types of molecules will be in preferred compartments in the cell. Sugars are not involved in fluidity of the membrane because there are no sugars within the membrane. Sugars are not found within the membrane because they have a lot of hydroxyl groups which makes makes them highly polar. An atom"s ability to draw electrons towards its core. The more electronegativity, the more electrons are drawn towards its core, giving an uneven distribution of charge between the atoms. This gives a more positive and more negative end. Electronegativity and polarity is crucial for this course. Important to build proteins and interaction between molecules. Oxygen: think there is going to be some pull on the electrons. If an amino acid is polar, it tends to be hydrophilic will be within folded portion of the membrane. If its nonpolar then its hydrophobic and prefers lipids.
