Card Set Information
Composed primarily of carbon, hydrogen, and oxygen atoms and range in size from small to very large.
Large carbohydrates are composed of numerous, relatively simple building blocks (simple sugars)
Composed of two simple sugars bound together through a dehydration reaction.
Consist of many monosaccharides bound together to form long chains that are either straight or branched.
A second major group of organic molecules common to living systems.
Consists of a straight chain of carbon atoms with a carboxyl group attached at one end.
A 3-carbon molecule with a hydroxyl group attached to each carbon atom.
Contains only single covalent bonds between the carbon atoms.
Saturated fatty acid
Has one more double covalent bonds between carbon atoms.
Unsaturated fatty acid
Differ in chemical structure from other lipid molecules, but their solubility characteristics are similar.
Similar to triglycerides , except that one of the fatty acids bound to the glycerol is replaced by a molecule containing phosphate and usually nitrogen.
Constitute 95% of the fats in the human body.
The polar end of the molecule is attracted to water and is said to be…
The nonpolar end is repelled by water and is said to be…
What are the building blocks of a polysaccharide?
What are the building blocks of lipids?
What are the three groups of lipids?
Steroids, cholesterol, triglyceride
What is unique about the structure of a phospholipid?
Phosopholipids have both a hydrophilic (water loving) and hydrophobic (water hating) region. This enables them to effectively make a barrier between the fluid inside and outside of the cell.
