from systematic errors (deterministic error) or random error (not deterministic error). In this experiment‚ the group measured the diameter of sphere using different kinds of measuring devices (foot rule‚ vernier caliper‚ and micrometer caliper) in order to achieve accuracy in the scientific measurements. After experimenting‚ it was revealed that the micrometer caliper has the lowest percentage of error. 1. Introduction In the early days‚ people used mostly human body parts for measuring. And because

EXPERIMENT 1: REACTIONS OF ENOLATE IONS WITH CARBONYL GROUPS Aims In this experiment we used two techniques for the reactions of enolate ions with carbonyl groups. One technique used was Doebner reaction and the other technique used was Claisen-Schmidt reaction. Therefore the aim of this experiment is to synthesize trans p-methoxycinnamic acid and to synthesize dibenzalacetone via an aldol condensation reaction between acetone and benzaldehyde. The products would be recrystallized using ethanol

Description This program will determine the usable area of a house. The rooms are rectangular in shape and maximum of four rooms are allowed to be calculated at once. It will use the area formula for a rectangle to find the usable area of each room and once the calculation are made for each room it will print out the total usable area of a house to the output screen. Analysis This program will calculate the usable area in square feet of a house with a maximum of four rooms that are rectangular

Where ’s the Protein? Proteins‚ which are constructed from amino acid monomers‚ are considered one of the four major macronutrients needed by the body‚ along with carbohydrates‚ lipids‚ and nucleic acids. Only the first three nutrients listed require delicate balancing. One must consider the sources from which he or she receives those required nutrients. Carbohydrates from fruits‚ vegetables‚ and grains; lipids from oily animals such as fish or plant foods like avocados; and proteins from meats‚

Intact protein and base hydrozylate have different color reactions when subjected into various tests. The protein used is Casein which was isolated from milk. Color reactions ‚in these test‚ gives off the information about the composition of a protein. Results often varies from being positive to one and negative to another since one has its peptide bond intact while the other is broken. The different tests that are used in this experiment are : biuret test‚ Sakaguchi test‚ ninhydrin test‚ xanthoproteic

Background: Pepsinogen is an inactive protein that is the mucus lining of the stomach. When converted to pepsin‚ the enzyme is used to break down large or undigested protein they has been absorbed by the small intestine. The digestive power of pepsin is greatest at the acidity of normal gastric juice (pH 1.5–2.5). In the intestine the gastric acids are neutralized (pH 7)‚ and pepsin is no longer effective.
