Stomach or compound racemose resembling the duodenal Brunner's glands The "fundic glands", are found in the fundus and body of the stomach. They are simple almost straight tubes, two or more of which open into a single duct. They secrete hydrochloric acid (HCl) and intrinsic factor. The "pyloric glands" are located in the antrum of the pylorus. They secrete gastrin produced by their G cells. About 20,000 protein coding genes are expressed in human cells and nearly 70% of these genes are expressed in the normal stomach. Just over 150 of these genes are more specifically expressed in the stomach compared
Benzoic acid drinks (phosphoric acid), pickles (vinegar) or other acidified food are preserved with benzoic acid and benzoates. Typical levels of use for benzoic acid as a preservative in food are between 0.05–0.1%. Foods in which benzoic acid may be used and maximum levels for its application are controlled by local food laws.

Benzoic acid is a constituent of Whitfield's ointment which is used for the treatment of fungal skin diseases such as tinea, ringworm, and
