Summary Introduction
Introduction:
Saturation of fatty acids depends upon the presence of bonds. The saturated fatty acids contain only single bonds. The unsaturated fatty acids contain one or more double bonds.

Name and describe the four different categories of lipids including their structures and functions; be sure to discuss both saturated and unsaturated fatty acids
Truel False: you are asked to determine if the statement is TRUE or FALSE, You must write out the word ENTIRELY for full credit. If the statement is FALSE, you must
provide the reason WHY the statement is false in the space below the statement. Do not just change one word, EXPLAIN why it is false.
