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.

Answer:
The general preparation of esters( for example ethyl ethanoate) is through a process known as ESTERIFICATION.
Explanation:
The formation of an ester by the reaction between an alkanol and an acid is known as esterification. This reaction is extremely slow and reversible at room temperature, and is catalyzed by a high concentration of hydrogen ions.
In the preparation of one of the simpler esters known as ETHYL ETHANOATE the reactants include ethanol(an alcohol) and glacial ethanoic acid(a carboxylic acid) in the presence of concentrated tetraoxosulphate VI acid as a CATALYST. Note that, a catalyst is any substance that is able to increase the rate of a chemical reaction.
The mixture is warmed in a water bath( hot but not boiling) for about 25 minutes. The mixture is poured into a beaker partially filled with a sodium or calcium chloride to remove interacted ethanol. The ethyl ETHANOATE floats on the mixture as oily globules.
Answer:
The muscular system is composed of specialized cells called muscle fibers. Their predominant function is contractibility. Muscles, attached to bones or internal organs and blood vessels, are responsible for movement. Nearly all movement in the body is the result of muscle contraction.
