WebEsters are formed by the condensation reaction between an alcohol and a carboxylic acid. This is known as esterification. In a condensation reaction, two molecules join and produce a larger molecule whilst eliminating a small molecule. During esterification this small molecule is water. Esters have characteristic smells and are insoluble in water. WebDepending on the actual way the lesson is organised, this may be designed to take from 15 minutes to an hour.

WebWhen you chew carbohydrate-rich foods, carbohydrase enzymes, such as amylase in your saliva, break down starch into sugar to give us the energy we need. Then protease … WebStructure of esters. To make an ester, a hydrogen atom must be removed from the hydroxyl group (–OH) of the alcohol. The –OH portion of the acid's carboxyl group must also be removed. The hydrogren atom and the -OH combine to form a water molecule (H2O). \ [propanol + ethanoic\,\,acid \rightleftharpoons propyl\,\,ethanoate + water\]
WebLipids are usually grouped together on the basis of their solubility in nonpolar solvents, and are classified in three subgroups based on chemical composition: hydrocarbons, simple lipids, and complex lipids. Hydrocarbons contain carbon and hydrogen only. WebKevlar is similar in structure to nylon-6,6 except that instead of the amide links joining chains of carbon atoms together, they join benzene rings. The two monomers are benzene-1,4-dicarboxylic acid and 1,4-diaminobenzene. If you line these up and remove water between the -COOH and -NH 2 groups in the same way as we did with nylon-6,6, you …
Web'Change' refers to the change in the substance being measured.
