Serotonin acts as a weak base and has a pkb = 3. 84. what is the ph of a solution made by adding 0. 025 m of serotonin in water?
Zarrin [17]

Serotonin acts as a weak base and has a pkb = 3. 84. The ph of a solution made by adding 0. 025 m of serotonin in water is 2.4.

A molecule called serotonin delivers information between nerve cells in the brain and other parts of the body. Body processes like mood, sleep, digestion, nausea, wound healing, bone health, blood clotting, and sexual desire are all significantly influenced by serotonin.

Tryptophan, an important amino acid, is used to make serotonin. This amino acid, which must be ingested by food, is frequently present in foods including nuts, cheese, and red meat. Lower amounts of serotonin can result from tryptophan insufficiency. Anxiety or depression may come from this, among other mood disorders. The chemical serotonin is essential for elevating mood and lowering anxiety.
