1 Slate can start as low as $1-$3 a square foot for basic floor tiles. 2  Depending on size, finish, thickness and color, higher quality slate tiles can cost $4-$10 a square foot, while mosaics and other specialty tiles (usually used as accents) can be $8-$35 a square foot for just the tiles. Slate sealer costs $10-$30 a gallon. 2  For a shiny or matte finish or if the slate is relatively porous (tending to stain), the slate should be sealed before and after installation, and then every one to two years, depending on the amount of traffic and wear on the floor.
Save. Amylase and lipase are digestive enzymes produced by the pancreas. Amylase and lipase tests are used to distinguish acute appendicitis from acute pancreatitis. Both tests are done on blood, but amylase may also be tested from a urine sample.
The Importance of Lipase. Fats require special digestive action before absorption because the end products must be carried in a water medium (blood and lymph) in which fats are not soluble. Lipase is the primary digestant used to split fats into fatty acids and glycerol. Although little actual fat digestion occurs in the stomach, gastric lipase does digest already emulsified fats such as in egg yolk and cream. Emulsification is the real key to the proper digestion of fats.
