Metabolómica de la lágrima

Abstract: La lágrima es un fluido corporal con una compleja composición. Se estructura en 3 capas: lipídica, acuosa y mucinosa. Los lípidos (fundamentalmente colesterol) proceden de la secreción por las glándulas de Meibomio, además de las de Zeiss y Moll. El componente acuoso, secretado por las glándulas lacrimales mayores y accesorias, contiene una gran cantidad de moléculas disueltas, como electrolitos (sodio, potasio, calcio, magnesio, cloro, fosfato, bicarbonato, etc.), péptidos y proteí-nas (enzimas, factores de … Show more

“…The mucoaqueous layer of the tear film contains electrolytes (such as sodium, potassium, calcium, magnesium, chlorine, phosphate, bicarbonate), protein fragments as peptides, and metabolites (such as amino acids, urea, glucose, lactate). Because the levels of the latter are low (confounded by low volumes of sample), the tear metabolome is poorly characterized [529]. …”
