Thu, January 21-INTRODUCTION TO CELL BIOLOGY
The larger ones; they are good for storage and structure
Important macromolecules on this slide
o(will be covered later in the course)
oIn a cell how do these macromolecules interact with each other, what ability
does it provide to the cell?
oThe main topic-POLARITY
oElectronegativity-tend to attack electrons from neighbouring atoms, creates
an uneven distribution of charge between those atoms..
oThis creates areas that are slightly more or less positive or negative.
oEX) oxygen with hydrogen AKA WATER
oElectronegativity increases as you go up from left to right on the
****Will not be asked to draw recognize or memorize the twenty structures,
but will be asked to talk about its properties by looking at the structure, why
or why not it is polar, charged or uncharged, or acidic or basic.
The coloured portions are different for all of the structures
