Amylase is a very important enzyme located in the saliva and pancreatic juices that hydrolyses (break down) starch and glycogen into more simple and readily digestible forms of sugar. Enzymes are biological catalysts that increase the rate of biological reactions. Enzymes are produced in living cells and are involved in speeding up biochemical reactions. They have an active site to which specific substrate binds. They increase the rate of reactions by decreasing the amount of activation energy meaning

and glycogen are three carbohydrates that are similar‚ but structurally different. Carbohydrates have the general molecular formula CH2O. Starch and cellulose are the two most common carbohydrates. Both are polymers (hence "polysaccharides"); that is‚ each is built from repeating units‚ monomers‚ much as a chain is built from its links. The monomers of both starch and cellulose are the same: units of the sugar glucose. Carbohydrates are one of the four major classes of organic compounds in living cells

Carbohydrates‚ Proteins‚ lipids‚ and nucleic Acid Lab Exercise 6 Date: 9/17/12 Bio 102-11 Purpose the purpose of this experiment was to perform test to detect the presence of carbohydrates‚ proteins‚ lipids‚ and nucleic acids. Explain the importance of a positive and a negative control in biochemical test. Use biochemical test to identify an unknown compound. Background Most organic compounds in living organisms are carbohydrates‚ proteins‚ lipids‚ and nucleic acids they are called macromolecules

content was 7.03-14.14%. However‚ the protein content of selected chicken frankfurter is also lower than commercial chicken sausages‚ which was 13.2%. The low protein content may be due to the formulation designed in manufacturing of sausage where the starch is substituted to replace the raw meat hence reducing the processing cost while improving the texture of mechanically-recovered meat. Based on Malaysian Food Regulation 1985‚ the manufactured meat in the form of sausage should contain not less than

Laundry It is a place where the washing & finishing of clothes & other washable articles are carried out. There are two types of laundry. Off premises /Contracted laundries 1. Caters to hotels on contract basis 2. No heavy investment 3.Quality may not be maintained as per the brand standard of the hotel 4.Timings are fixed for delivering the laundered linen 5.A good amount of par stock has to be kept for emergency purpose. On Premises/ In house laundry 1. it is present in the hotel

* Glucose+ GA lactose lactose * Glucose +Glucosemaltose Starch * It acts as a store of energy which can be converted back into glucose when required. It can be found in 2 forms: * The polysaccharides of amylose (50-500 glucose units in a straight line) * Amylopectin (Which contains up to 100000 glucose units in a branch like structure) Polysaccharides Glycogen: is the bodies’ equivalent to starch. It is stored in the liver and muscles and is Brocken down into glucose
