Pancreatin is a digestive enzyme produced by the pancreas and delivered to the small intestine for the hydrolysis of complex nutrients. Pancreatin contains enzymatic components including trypsin, amylase and lipase, ribonuclease, and protease, produced by the exocrine cells of the porcine pancreas.…

Lactulose is used as a test of small intestine bacterial overgrowth (SIBO). Lactulose is used in the treatment of chronic constipation. It is useful in treating the hyperammonemia caused by hepatic encephalopathy, because it helps "draw out" ammonia from the body. Lactulose is also a food…

Hemoglobin is used to study paradigm for the regulation of gene expression and cellular differentiation. Hemoglobin is the major component of red blood cells, and is responsible for their red color. A major oxygen-transporting component of red blood cells, it's normal concentration in…
