The article discusses the introduction of an integrated curriculum on General, Organic and Biochemistry course at Georgia Southern University in Statesboro, Georgia. Its integration will fulfill the chemistry requirement for nursing majors, as well as a requirement for the first two chemistry courses for students taking up nutrition majors. The school's curricular reform was designed to de-emphasize some topics and to integrate others to provide necessary fundamentals of chemistry. The introduction of the curriculum has brought positive outcome as indicated in the improved course evaluations.

The article focuses on electrophilic aromatic substitution (EAS) laboratory that can reduce the hazardous wastes generated in organic chemistry laboratories. EAS laboratory aims to secure the safety of the students and reduce the costs associated with wastes disposal, and it carries out a multistep procedure using aniline, acetic anhydride, and mixture of nitric and sulfuric acids to produce p-nitroaniline. An analgesic called Salicylamide is used as starting material for EAS because the directing effects of the substituents on the aromatic ring complements each other. The iodination of salicylamide is successfully adapted to generate iodine electrophile. Other details of EAS laboratory is also discussed.

Analyzes the implication of carbohydrate composition for banana ripening. Duration of refrigerated banana ripening; Variables considered in food and eating; Role of food refrigeration in delaying ripening process.

Features an isolation, purification and characterization of enzymes as laboratory projects for undergraduate biochemistry. Significance of laboratory projects; Modification on the purification of lysozymes from egg whites; Determination of the kinetic parameters of acid phosphatase; Time frame of the projects; Advantages of efficient use of time.

Presents a laboratory exercise that employs a discovery-type or puzzle-oriented experiment to develop the students' problem solving abilities and enhance their critical thinking skills. Experimental procedures.

Presents a method of constructing a flash chromatography system that utilizes aquarium pumps and valves in the construction of the apparatus combined with other materials already available in a typical academic laboratory. Materials and methods; Results and conclusions.

The article discusses the use of alternative procedure in analyzing carbohydrates in bananas following a laboratory experiment on ripening bananas that was published in the previous issue in the U.S. In this experiment, the authors used over the counter glucose test strips to incorporate with the previous experiment. They also employed laboratory mortars and pestles in place of the homogenizers and refrigerated centrifuges to avoid difficulties for students who are not familiar of their use. This article presents the methods and procedures used in the study.

Focuses on a laboratory component which was designed to utilize foodstuffs and their chemistry to allow students at the Department of Chemistry at Georgia Southern to investigate biochemical principles relevant to nutrition. Information on many of the experiments used in the biochemistry laboratory; Details on the nutritional role of enzymes; Materials used by students to assay the activity of the enzyme lactase in a solution of lactose milk.
