ANATOMY

Detailed explanation-1: -Thus, saturated fatty acids contain no carbon-to-carbon double bonds, monounsaturated fatty acids contain one carbon-to-carbon double bond, and polyunsaturated fatty acids contain two or more carbon-to-carbon double bonds. Table 17.1. 1 lists some common fatty acids and one important source for each.

Detailed explanation-2: -Saturated fatty acids (SFA) have no double bonds, while monounsaturated fatty acids (MUFA) have one double bond and polyunsaturated fatty acids (PUFA) have two or more double bonds.

Detailed explanation-3: -Saturated fatty acids do not contain any double bonds or other functional groups along the chain. Unsaturated fatty acids contain at least one pair of carbon atoms linked by a double bond enabling the addition of other atoms to these carbons.

Detailed explanation-4: -Fatty acid chains with no double bonds are saturated, because each carbon is saturated with as many bonded hydrogen atoms as possible.

Detailed explanation-5: -When a fatty acid is saturated, each carbon is bound to two carbons-each by a single bond-with two hydrogens taking up the remaining bonds on either side. But sometimes, the carbons bond to each other with double bonds, leaving room for only one hydrogen.
