Alkaloids usually have a bitter taste
Papaya can taste bitter due to the presence of compounds called alkaloids, specifically carpaine. These compounds can give the fruit a bitter taste, especially when it is not fully ripe.
Alkaloids are devided based on their shape and origin. 1.True alkaloids 2.protoalkaloids 3.pseudoalkaloids True alkaloids derive from amino acid and they share a heterocyclic ring with nitrogen. true alkaloids have bitter taste and appear as white solid, with the exception of nicotine which appear as brown liquid. True alkaloids form water soluble salts.
Papaya can taste bitter due to the presence of compounds called alkaloids, specifically carpaine. These compounds can give papaya a bitter taste, especially when the fruit is not fully ripe.
Sour taste is typically triggered by acidic compounds like citric acid, which stimulate taste receptors that detect acidity. Bitter taste, on the other hand, is often associated with compounds like alkaloids, found in substances like caffeine and quinine, which activate different taste receptors. The taste of a food item depends on the specific chemical compounds present in it.
A bitter taste in papaya can be caused by the presence of certain compounds called alkaloids, which can develop when the fruit is not fully ripe or has been stored improperly. Additionally, overripe papayas can also taste bitter due to the breakdown of sugars in the fruit.
There are many species which sequester alkaloids from plants, usually as a self-defence mechanism. Absorption of alkaloids by such species will usually render the organisms unpalatable largely because of the bitter taste that results. Certain ant, caterpillar, mite, frog, etc. species extract - and possibly metabolise - plant alkaloids to synthesise new ones or may simply secrete those absorbed during feeding on plants containing them.
Alkaloids taste bitter because they bind to and activate taste receptors on the tongue, specifically the bitter taste receptors. These receptors are sensitive to a wide range of substances, including chemicals often found in plants like alkaloids. The perception of bitterness helps animals distinguish potentially harmful substances in their environment.
Alkaloids excite gustatory hairs at the taste buds by interacting with taste receptors, inducing a variety of sensory responses depending on the specific alkaloid. This can result in bitter, sweet, or umami taste sensations.
Just plain old chocolate with nothing added is quite bitter. This is because chocolate contains alkaloids which are usually poisonous and . . . bitter. Chocolate is considered a very mild poison . . . not the kind that will kill you, but the kind that can make you feel not very good fir awhile.

Examples of alkaloids are: the local anesthetic and stimulant cocaine; the psychedelic psilocin; the stimulants caffeine and nicotine; the analgesic morphine; the antibacterial berberine; the anticancer compound vincristine; the antihypertension agent reserpine; the cholinomimetic galantamine; the anticholinergic agent atropine; the vasodilator vincamine; the antiarrhythmia compound quinidine; the antiasthma therapeutic ephedrine; and the antimalarial drug quinine. No matter the type or use, alkaloids invoke a bitter taste.

other chemical compounds in food and send signals to the brain to interpret the taste. Taste cells are located in taste buds on the tongue and play a crucial role in detecting and identifying different flavors in food.

it contains 25 quinoline alkaloids .important alkaloids are quinine, quinidine, cinchonine & cinchonidine. Other alkaloids are quinicine ,cinchonicine, hydroquinine & hydrocinchonidine. Also contains Quinovin , a bitter glycoside responsible for bitter taste,yields on hydrolysis of quinovic acid and quinovosc,a sugar derivative.cinchona bark also contains tannins as quinic acid and cincho tannic acid.
