Syntonin or acid albumin is an intermediate product of the gastric digestion of albuminates, or proteids, which are eventually transformed into peptones. Syntonin may be produced outside the body by the prolonged action of dilute hydrochloric acid upon minced muscle. It is precipitated by sodium chloride and many other salts, as well as by neutralisation with alkalis, but not by heat.
 Research Syntonin
Urine is a fluid produced by the kidneys. Urine contains the end products of nitrogen metabolism - urea, uric acid and creatinine as well as sodium chloride. Urine is extensively tested in medicine for the diagnosis of disease, and immunological analysis of urine is commonly used to test for pregnancy in humans.
In industry, a dilute solution of urine was long traditionally used as a degreaser for sheep's wool before it was combed, spun and woven.
