Steps in the process involve 1) oxidation of the terminal methyl group of the fatty acid to an alcohol; 2) oxidation of the alcohol to an aldehyde, and 3) oxidation of the aldehyde group to a carboxylic acid (Figure 6.94). a.natural therapy The gel-to-foam mix is gentle on all skin types, cleans and soothes, and contains anti-aging properties. b.balance alcohols fatty acids reduction acids acid Prior art date 1936-12-19 Legal status (The legal status is an assumption and is not a legal conclusion. While amino acids are the compounds that contain both; a carboxyl group at and an amino group attached to the same carbon atom. There are three carboxylic acid portion in these molecules since each glycerol molecule can be esterified with a different carboxylic acid. a.act as vehicles in some products For example, sodium benzoate is the sodium salt of benzoic acid while lauryl benzoate is the ester of benzoic acid and lauryl alcohol. The high activity of this enzyme probably accounts for the extremely low levels of unesterified fatty alcohols generally found in tissues or blood.
