Oligosaccharides - up to ten (ish) monosaccharides
They tend to have variability so they're not just the same monosaccharide repeated
over and over again
○
○
Monosaccharides are connected to each other to make larger molecules by glycosidic
bonds
It's basic building block is (CH2O)n
○
○
Glucose is a hexose
○
Has an alpha bond
We either have an alpha or beta bond and alpha goes under the ring while beta goes
from under and then over the surface of the ring
○
○
There is a significant amount of variability
○
Typically of repeated monosaccharides or disaccharides
We are able to digest starch and glycogen but not cellulose because cellulose has a
beta bond and we cannot digest it
○
We store glycogen

Also known as triglycerides - they have three fatty acids and a linker molecule called
glycerol
Triacylglycerol is also another name for a fat
○
○
Measured in mJ/kg
○
Highly specialized cells just for fat storage
○
Monomer of fat and also a component of lipids is the fatty acid
The long chains are water insoluble

Document Summary
Life would not be possible without these four macromolecules. They are huge long chains of molecules, however lipids are typically smaller. They can form polymers - long chains of repeating structures called monomers. When the electrons are closer to the positively charged nucleus. They tend to have variability so they"re not just the same monosaccharide repeated over and over again. Monosaccharides are connected to each other to make larger molecules by glycosidic bonds. We either have an alpha or beta bond and alpha goes under the ring while beta goes from under and then over the surface of the ring. We are able to digest starch and glycogen but not cellulose because cellulose has a beta bond and we cannot digest it. Also known as triglycerides - they have three fatty acids and a linker molecule called glycerol. Triacylglycerol is also another name for a fat. Monomer of fat and also a component of lipids is the fatty acid.
