La lactosa es un disacarido presente en la leche de los mamiferos que supone la mayor fuente de hidratos de carbono durante la lactancia. Se sintetiza por accion de la lactosa sintetasa a partir de la glucosa en la glandula mamaria, y esta formada por una molecula de glucosa y otra de galactosa unidas por un enlace -1,4. La lactosa de la dieta se hidroliza a galactosa y glucosa por accion de una disacaridasa, la lactasa-floricina hidrolasa (LPH), una -galactosidasa de 150 kDa sintetizada en los… 

Microencapsulación de la lactasa como estrategia para mejorar la estabilidad y la aplicación en la industria de alimentos

La leche y sus derivados lacteos son uno de los alimentos de mayor aceptacion a nivel mundial por su alto valor nutritivo en funcion de sus macronutrientes y micronutrientes. Dentro de los

Intolerancia a la lactosa

Lactose intolerance (LI) is the most common malabsorption syndrome in childhood and adolescence, and manifests itself as pain, abdominal trouble, diarrhoea, flatulence, abdominal distension, nausea and even vomiting.

Obtención de ácido láctico a partir de suero de leche mediante un proceso biofermentativo utilizando un cultivo mesófilo homofermentativo

Este proyecto se realizo con el fin de utilizar el suero lacteo residual del proceso de elaboracion de queso, como materia prima para la obtencion de acido lactico. Se realizo un diseno experimental

Intolerancia a la lactosa

La lactosa es un disacarido de amplia distribucion en la dieta y productos farmaceuticos, es el hidrato de carbono de la leche de los mamiferos. La intolerancia a la lactosa puede presentarse como

Situación actual de la intolerancia a la lactosa en la infancia

The exclusion of lactose from the diet produces clinical improvement but it could lead to a defect in the recommended daily intake of other nutrients such as calcium, so there is an individual clinical threshold of tolerance.

There is scarce literature regarding Lactose Quick Test (LQT) and concordance with other methods for lactose intolerance diagnosis in children and there is a need for more research into these methods.

Lactose and Lactase—Who Is Lactose Intolerant and Why?

Any hypothesis for the control of lactase expression must reconcile the presence of high levels of activity in early life in all humans and the characteristic loss of activity found subsequently in many but not all people.

Identification of a variant associated with adult-type hypolactasia

A DNA variant, C/T−13910, completely associates with biochemically verified lactase non-persistence in Finnish families and a sample set of 236 individuals from four different populations, indicating that it is very old.

The T allele of a single-nucleotide polymorphism 13.9 kb upstream of the lactase gene (LCT) (C-13.9kbT) does not predict or cause the lactase-persistence phenotype in Africans.

It is concluded that the C-13.9kbT polymorphism is not a predictor of lactase persistence in sub-Saharan Africans, and Y-chromosome data is presented that is consistent with previously reported evidence for a back-migration event into Cameroon.

Prevalence of lactose malabsorption in Galicia.

The results suggest the importance of BH2 testing following ingestion of usual consumed amounts of lactose per serving and the frequency and number of gastrointestinal symptoms were significantly higher in LM than in lactose absorption (LA).

Decline of Lactase Activity and C/T-13910 Variant in Sardinian Childhood

In Sardinians, adult-type hypolactasia becomes phenotypically evident in all individuals older than 9 years, suggesting that this should be considered the minimum age at which the genetic test for lactase nonpersistence should be applied.
