Task 1 • Describe the structure of an enzyme as a protein‚ in terms of tertiary/ quaternary structures. 1) Primary Structure This is in reference to the order of way that amino acids are connected to form a protein. These are built up from 20 amino acids‚ and follow these structures o A carbon (the alpha carbon) bonded to the four groups below: o A hydrogen atom (H) o A Carboxyl group (-COOH) o An Amino group (-NH2) o A "variable" group or "R" group 2) Secondary Structure This is in reference

Dasmariñas Dasmariñas‚ Cavite Philippines ABSTRACT This experiment was performed to learn the technique of acid-base titration and to compare the efficiency of commercially available antacids by looking at their weight of HCl and weight of antacid values. The analysis of antacid tablets was highlighted in this experiment. The efficiency of antacid tablets was determined and compared when the number of grams of HCl can be neutralized by 1 gram of the tablet was found. First‚ the two antacid tablets

Biotechnology‚ Mapua Institute of Technology ABSTRACT In this experiment‚ solubility class of various organic compounds are to be determined. The main objective of the experiment is to identify an unknown compound through the use of preliminary tests such as examination of physical state‚ color‚ odor‚ and ignition properties. Also‚ solubility tests were used to further examine an unknown compound’s solubility class. In this experiment‚ the apparatus used are micro test tubes and droppers for mixing

can be done by protein electrophoresis. Protein electrophoresis involves the movement of proteins within an electric field with mobility being dependent on factors such as the size and shape (secondary and tertiary structure)‚ as well as the charge of the protein (due to primary structure). Other factors that can affect the mobility are electric-field strength‚ matrix pH‚ and ionic buffer strength of the electric field. Because there are so many factors involved in analyzing proteins during electrophoresis

vesicles facilitated by kinesin and the effects of mutations in nerve transmission in Caenorhabditis elegans Introduction A nerve cell is made up of three main structures: the soma‚ the axon and the synapse. When a nerve cell receives a signal‚ a protein called kinesin travels anterograde along the axon and guides the synaptic vesicles until it reaches the synapse. This triggers the release of the neurotransmitters stored within the vesicles. Once released‚ the neurotransmitters then bind to receptors
