Amino acid present in the lumen of the small intestine The goal is to cross through the epithelial cell membrane to enter into the epithelial cell’s cytoplasm – its charged cuz of side chains To get through the membrane the amino acid must cross the Simple columnar epithelial cells lining the apical surface of the small intestinal tract. These cells are impermeable to any harmful bacteria that may be ingested by the body‚ but permeable to necessary ions. Absorption of amino acids occurs through

Hypothesis: The higher the concentration of hydrochloric acid‚ the faster the reaction will take place because there will be more hydrochloric acid particles to collide with the marble chip particles therefore resulting in a quicker reaction. The lower the concentration‚ the weaker the reaction will be as there will be fewer particles so less chance of a collision and a lower rate of reaction. Equipment: Conical flask – to hold the hydrochloric acid and marble chips Boiling tube – to hold and indicate

INTRODUCTION Sulphuric Acid is an important chemical‚ which has large-scale industrial uses. Its major user is the phosphate fertilizer industry. Other important applications are in petroleum refining‚ steel pickling‚ rayon & staple fiber‚alum‚ explosives‚ detergents‚ plastics and fibers etc. Sulphuric Acid Industry is very old and has been continuously adopting the technological developments. It started with Lead Chamber process followed by contact rocess with Single Conversion Single Absorption

This experiment is to show how much carbon dioxide is produced during the reaction between an acid (hydrochloric acid) and marble. Equipment: Hydrochloric Acid (20ml) - 0.5M‚ 1M‚ 2M Marble Chips (2g per test) Large Measuring Cylinder Plastic Bowl (3/4 full of water) Rubber Tubing Glass Conical Flask Stopwatch Method The first thing that we did was fill the plastic bowl with water. We only filled it up 3/4 of the way because otherwise the water displaced into

most simple bath bomb recipes have: baking soda‚ citric acid‚ and cornstarch. When baking soda and citric acid are mixed together with some water‚ they undergo a chemical reaction. Specifically‚ this reaction involves acid-base chemistry‚ since the baking soda—also known as sodium bicarbonate (NaHCO3)—is a weak base‚ and citric acid (C6H8O7) is a weak acid. This reaction is shown in Equation 1‚ below. As you can see from Equation 1‚ the acid-base reaction produces carbon dioxide (CO2) gas. This gas

Abstract Our study is entitled “The Feasibility of Aspartic Acid found in Oyster Shells as an additive ingredient in improving the absorbency of commercialized sanitary napkins.” The objective of the study was to extract a protein from the oyster shells to produce aspartic acid which can replace the manufactured polymer found in commercialized sanitary napkins. The significance of our study is that the product is an alternative in producing polymers. It is also environmental friendly; biodegradable
