Pharmaceutics Experiment 2 Preparation of a Hand Cream OBJECTIVE 1. To learn the method of preparing a hand cream. 2. To appraise the function of the ingredients in the hand cream. BACKGROUND Cream is a kind of dosage form and particularly hand cream is formulated to carry out a variety of cosmetic functions. Among these are softening and moisturizing the skin; elimination of natural waste products (oils) by emulsification; and cooling the skin by radiation‚ thus helping to maintain body temperature

Without Interface the computer cannot access the Media. Without the signal the electricity or copper wires cannot transmit information. Without Pattern there would be no established format for the signals. And timing lets the devices know when the pattern starts and ends.

introduction to enzymes Enzymes are the foundation of energy and the life force in all living things. They are responsible for building‚ detoxifying‚ and healing the body. They are also the force that allows your body to digest and absorb food. Enzymes also regulate tens of thousands of other biochemical functions that take place in the body every day. Without enzymes‚ seeds would not sprout‚ fruit would not ripen‚ leaves would not change color‚ and life would not exist. Therefore‚ the study of enzymes has

Rate of Enzyme Activity Justin Hunter G. Kim September 16‚ 2011 September 26‚ 2011 Abstract Catalase is a common enzyme found in nearly all living organisms that is frequently used by cells to rapidly catalyze the decomposition of hydrogen peroxide into less reactive oxygen and water molecules. Catalase is a protein that is most commonly found in the liver. The purpose of this experiment was to determine the effect that changes in temperature and pH have on the function of the enzyme catalase

Enzymes control the rate of metabolic reactions‚ they act as biological catalysts‚ which means they are used but not used up and they also control the speed of the reaction. Enzymes are proteins which means that anything that disrupts this structure such as high temperature or change in pH will affect the enzyme activity. There are many factors affecting enzyme action for example temperature effects them‚ if the Increasing the heat gives molecules more kinetic energy so they vibrate this can then
