Mucosa, gastric carbohydrates

IonPac KC-811 column separated the labile compounds N-acetylneuraminic acid and N-glycolylneuraminic acid released by mild acid hydrolysis of bovine vitronectin.245 Sialic acid is extremely labile to conditions of handling and must be released by mild acid hydrolysis.246 Derivatization with phe-nylisothiocyanate and separation by reversed phase chromatography was found useful in analysis of hexosamines from gastric mucosa.247 A review on separation of sugars and other carbohydrates which covers many important aspects is available.248... [Pg.252]

Molar Ratios of Sphingosine and Carbohydrates in the Highly Complex Fucolipids from Gastric Mucosa. [Pg.164]

As previously discussed, food effects are an important parameter for enteric-coated systems, especially for drugs, that are sensitive to food. Pancreatic enzyme-containing products fail when they come in contact too early with lipids, proteins, and carbohydrates present in food. The clinical efficacy of pancreatic enzymes formulated as enteric-coated tablets was investigated in man and dog [44], The enteric materials examined were hydroxypropyl methylcellulose phthal-ate (HPMCP), cellulose acetate phthalate (CAP), and the methacrylic acid copolymer USP/NF Type C. In vivo behavior monitored by x-ray scintigraphy showed clear differences between the three coating formulations. HPMCP-coated products adhered to the gastric mucosa, whereas CAP and methacrylate copolymer... [Pg.29]

Carbonic anhydrase and sodium bicarbonate together neutralize the acids produced by bacterial metabolism of dietary carbohydrate (Fig. 12.2). When salivary carbonic anhydrase is swallowed, it adheres to the mucosal surface of the stomach where it remains active and forms carbonic acid from sodium bicarbonate in the gastric mucosa. A lack of salivary carbonic anhydrase causes acid to remain longer in the stomach, contributing to peptic disease in addition to dental caries (Sect. 15.3.3). [Pg.206]

Clinicians who used test meals discovered that carbohydrates ferment in neutral gastric contents, with the production of lactic acid. Because acid secretion is reduced in patients with cancer of the stomach and because Oppler-Boas bacteria flourish in neutral gastric contents, the test for lactic acid in recovered test meals was for a while an important diagnostic procedure. Discovery of this source of lactic acid helped lay to rest the repeated assertion that the gastric mucosa secretes lactic instead of hydrochloric acid. [Pg.342]
