Biology/Chemistry 260 Nutrition and Metabolism
 Beloit College > Chemistry > Nutrition and Metabolism

Nutrition and Metabolism: Biochemical Mechanisms
Molecular biology, bioenergetics, and regulation of cellular processes. Metabolism of carbohydrates, lipids, amino acids, and nucleic acids. Laboratory experiments investigate metabolism and electron transport utilizing techniques for preparation and purification of enzymes, carbohydrates, and lipids. Three class periods and one laboratory period per week. Offered each spring. Prerequisites: Chemistry 230 and either any 100-level biology course or Chemistry 235.


 Course Information

Required Material:
Sareen Gropper and Jack Smith. (2013) Advanced Nutrition and Human Metabolism, 6th ed.
Safety goggles ($2)
Sewn laboratory notebook
Calculator with scientific notation

Inclusivity is a demonstration of equity and social justice through awareness, understanding, and respect for the differences in identity, culture, background, experience, and socialization, and the ways in which these forms of difference impact how we live and learn. Inclusivity requires equitable, institution-wide representation and access to resources. In practice, this manifests itself by each individual being aware of, committed to, and responsible for the well-being and care of all students, staff, and faculty.

Student Evaluation

Daily Quizzes (39 x 10 pts. each; drop 3 lowest) 360 points
Exams (3 x 100 pts.) 300 points
Labs (15 x 20 pts.; drop lowest) 280 points
Total 940 points

The three lowest daily quiz scores and the lowest lab grade will be dropped. If you miss class or lab for any reason (illness, religious observance, field or athletic trip, family, etc.), that day’s quiz or lab grade will be among those dropped. You should save these for when you need them. Missing more than three days of class and one day of lab will negatively affect your grade. The maximum number of absences allowed for this course is six combined class or lab periods. Missing more than this maximum will result in automatically failing the course.

Laboratory notebooks are due for grading at 9:00 a.m. each Thursday. There will be a box outside my office (SC 419).

Grading Scale A (93%-100%) A- (90%-92%)
B+ (87%-89%) B (83%-86%) B- (80%-82%)
C+ (77%-79%) C (73%-76%) C- (70%-72%)
D+ (67%-69%) D (60%-66%) F (less than 60%)
