Brunner's glands are known to produce neutral mucins. In order to achieve a better knowledge of their carbohydrate profile, we used five peroxidase-labeled lectins on surgical specimens of human duodenum. This method allowed us to identify at least two different types of neutral mucins in Brunner's glands secretion, thus demonstrating a heterogeneous mucin production. The structure of terminal oligosaccharidic chains in these glycoproteins has also been hypothesized.

D004386	Duodenum	The shortest and widest portion of the SMALL INTESTINE adjacent to the PYLORUS of the STOMACH. It is named for having the length equal to about the width of 12 fingers.	Duodenums
D006651	Histocytochemistry	Study of intracellular distribution of chemicals, reaction sites, enzymes, etc., by means of staining reactions, radioactive isotope uptake, selective metal distribution in electron microscopy, or other methods.	Cytochemistry
D006735	Horseradish Peroxidase	An enzyme isolated from horseradish which is able to act as an antigen. It is frequently used as a histochemical tracer for light and electron microscopy. Its antigenicity has permitted its use as a combined antigen and marker in experimental immunology.

D050260	Carbohydrate Metabolism	Cellular processes in biosynthesis (anabolism) and degradation (catabolism) of CARBOHYDRATES.	Metabolism, Carbohydrate
D037102	Lectins	Proteins that share the common characteristic of binding to carbohydrates. Some ANTIBODIES and carbohydrate-metabolizing proteins (ENZYMES) also bind to carbohydrates, however they are not considered lectins. PLANT LECTINS are carbohydrate-binding proteins that have been primarily identified by their hemagglutinating activity (HEMAGGLUTININS). However, a variety of lectins occur in animal species where they serve diverse array of functions through specific carbohydrate recognition.
