Although some mucins are membrane-bound due to the presence of a hydrophobic membrane-spanning domain that favors retention in the plasma membrane, most mucins are secreted onto mucosal surfaces or secreted to become a component of saliva.ature mucins are composed of two distinct regions: 1  The amino-and carboxy-terminal regions are very lightly glycosylated, but rich in cysteines. 2  A large central region formed of multiple tandem repeats of 10 to 80 residue sequences in which up to half of the amino acids are serine or threonine.
Pheromones are speculated to be present in human Saliva. Androsterone (a male Pheromone) is present in human Saliva (with higher concentrations in the saliva of males than that of females). Also, a small quantity of sodium chloride and urea is present in Saliva.Of great interest is the inclusion of IgA (an antibody) in Saliva.n average of one liter of saliva is produced within the body each day. The body's production of saliva is controlled by the Hypothalamus. Saliva is the initial endogenous chemical involved in the process of digestion and helps to neutralize acids that enter the body via the mouth.
