β¦ Synopsis
We have been able to demonstrate, that the hydrophobicity of the amino acid side chains is responsible for the bitterness of a peptide. Now we investigated lipids (and carbohydrates] in the following classes: Monoglycerides, diglycerides, phosphatides. lysophosphatides, monohydroxy fatty acids, dihydroxy fatty acids, trihydroxy fatty acids, monosaccharides, disaccharides. It was found that for lipids and carbohydrates the ratio from the number of the C-atoms of a molecule to the number of the hydroxyl groups nC -=R nnn called the R-values, gave a good indication as to whether the lipid or carbohydrate was sweet, bitter or non-bitter. For sweet compounds we found R = 1.00-1.99, for bitter compounds we found R ~2.00-6.99, and for non-bitter compounds we found a value of R higher than 7.00. These results confirm our earlier assumption, that like in the case of peptides, the bitterness of lipids and carbohydrates is caused by a certain range of the hydrophobicity.
