Other Associations
Evidence supports a genetic link between the Kell blood group (on chromosome 7 q33) and the ability to taste phenylthiocarbamide, or PTC, a bitter-tasting thiourea compound. Bitter taste receptor proteins in the taste buds of the tongue that recognise PTC are encoded on nearby chromosome locus 7 q35-6.

Famous quotes containing the word associations:
“There are many ways of discarding [books]. You can give them to friends,—or enemies,—or to associations or to poor Southern libraries. But the surest way is to lend them. Then they never come back to bother you.”
—Carolyn Wells (1862?–1942)
“Wild as it was, it was hard for me to get rid of the associations of the settlements. Any steady and monotonous sound, to which I did not distinctly attend, passed for a sound of human industry.... Our minds anywhere, when left to themselves, are always thus busily drawing conclusions from false premises.”
—Henry David Thoreau (1817–1862)
