Ethanolamine, also called 2-aminoethanol or monoethanolamine (often abbreviated as ETA or MEA), is an organic chemical compound with the formula HOCH 2 CH 2 NH 2.thanolamine is the second-most-abundant head group for phospholipids, substances found in biological membranes (particularly those of procaryotes), e.g., phosphatidylethanolamine. It is also used in messenger molecules such as palmitoylethanolamide, which has an effect on CB1 receptors.
Function. The exocrine secretion of the pancreas consists of enzymes that digest food in the small intestine, and sodium bicarbonate to neutralize hydrochloric acid from the stomach in the duodenum. See: pancreatic juice. The islets of Langerhans contain alpha, beta, and delta cells.
Caption: Goblet cell (yellow) in the mucosal lining of the small intestine (part of the digestive tract). A goblet cell secretes the mucus to protect the lining of the intestine and helps neutralize stomach acid.Inside the goblets cells are many mucigen granules (purple).When these are released into the intestine they will combine with water to form mucin, the main constituent of mucus. goblet cell secretes the mucus to protect the lining of the intestine and helps neutralize stomach acid.
