The given fatty acid has to be classified on the basis of omega classification system. Concept introduction: The position of double bonds in unsaturated fatty acids is denoted by the Greek lowercase letter omega ( ω ). The position of the double bond is specified relative to the methyl end or non-carboxyl end of the fatty acid carbon chain.

D- and L- designations are used to distinguish between the two possible
enantiomers of the monosaccharide, galactose.
From the Fischer projection, determine the designation of this
monosaccharide.
Using the tree structures for the following monosaccharides and comparing to
that for glucose, draw the structures of the following:
A. tree (Fischer) structures of: D-mannose and L-mannose
B. ring structures of alpha-D-mannose, beta-D-mannose, alpha-L-mannose, and beta-L-mannose
Draw the ring (Haworth) structures as 6-membered pyranoses, being careful to show the positions of the
hydroxyl groups above or below the plane of the ring.
In the monosaccharide derivatives known as sugar alcohols, the carbonyl oxygen is reduced to a hydroxyl group. For example, D-glyceraldehyde can be reduced to glycerol. However, this sugar alcohol is no longer designated D or L. Why?
