In order to work properly, taste buds rely on calcium receptors. [10] Zinc "is an important cofactor for alkaline phosphatase, the most abundant enzyme in taste bud membranes; it is also a component of a parotid salivary protein important to the development and maintenance of normal taste buds". [10]
Ageusia (from negative prefix a-and Ancient Greek γεῦσις geûsis 'taste') is the loss of taste functions of the tongue, particularly the inability to detect sweetness, sourness, bitterness, saltiness, and umami (meaning 'savory taste').

Some people lose the sense of smell and taste after COVID-19, making eating and drinking an unpleasant chore. Try some of these choices to make mealtime more pleasant.
The type II taste bud cells make up about another third of the cells in the taste bud and express G-protein coupled receptors that are associated with chemoreception. They usually express either type 1 or type 2 taste receptors, but one cell might detect different stimuli, such as umami and sweetness. [5]
Geographic tongue is characterized by areas of atrophy and depapillation (loss of papillae), leaving an erythematous (darker red) and smoother surface than the unaffected areas. The depapillated areas are usually well-demarcated, [ 4 ] and bordered by a slightly raised, white, yellow or grey, serpiginous (snaking) peripheral zone. [ 9 ]
