comparison of relative disaccharidase activities in jejunal mucosa , amniotic fluid , and meconium samples taken from the ileum , proximal and distal colon of 5 human fetuses , indicates that trehalase and lactase are more sensitive to the denaturation conditions existing in the fetal intestinal lumen than maltase , sucrase , palatinase and turanase . relative activities of sensitive disaccharidases ( trehalase and lactase ) were also low in the amniotic fluid of these fetuses as compared to the jejunal mucosa .
