The pancreatic juice is secreted by the pancreas. This pancreatic juice is secreted into the first part of the small intestine known as the duodenum. This pancreatic juice is rich in various enzymes that help in the digestion of various food components (carbohydrates, fats, and proteins). Besides being rich in enzymes, it is also rich in bicarbonate content. The bicarbonate works to neutralize the acidic chyme. This helps the enzymes to function and carry out digestion properly. If the pancreas fails to produce bicarbonate, then the function of enzymes will be altered, and the acidic chyme (coming from the stomach) will damage the small intestine walls.

Lignin
It is a complex organic polymer that form an important structural materials in the support system of vascular plants and can also be found in some algae. This is an important molecule in the structural composition of cell wall, such as in wood and bark. This also allow woods and barks to have strong, rigid which allows them to no break easily. Lignin can also be found inserted in the cell wall of this plants.
