Kevin Lowder and Dr. Tory Parker; Nutrition, Dietetics, Food Science This project was a very meaningful experience for me, as it allowed me to work closely with my mentor with the goal of publication in a scientific journal. I had approached Dr. Parker about working in his lab prior to applying for an ORCA grant, […]
Optimization and Standardization of the Oxygen Radical Absorbance Capacity (ORAC) Assay
Richard Low and Dr. Tory Parker, Nutrition Dietetics and Food Science Department Antioxidants, when consumed, have the ability to neutralize free radicals, suggesting their presence may protect human physiology from destructive oxidative processes1. Several assays have been developed that quantify the antioxidant capacity of compounds, and one assay that is commonly utilized by researchers and […]
Lactose Hydrolysis as a Method for Reducing Added Sugar in Chocolate Milk
Eric Engstrom Introduction Milk is a nutrient dense food that cannot be utilized easily by those with lactose intolerance. Lactose-hydrolysis is a process through which the native lactose in milk is enzymatically converted into its constituent sugars, glucose and galactose. Because this process digests the lactose in milk, the milk can then be digested by […]
Cholesterol Oxidation Products in Stored Egg Powder
Jonathan Swindler and Dr. Michelle Lloyd, Nutrition Dietetics and Food Science Department Cholesterol Oxidation Products (COPs) are a family of 27-carbon cholesterol oxidation derivatives that are formed from the auto-oxidation of cholesterol. They can result in food from high-temperature processing and storage. COPs have a variety of cytotoxic effects and are believed to be involved […]
Microbial Degradation of Folic Acid in Micronutrient Fortified Corn Masa
Brandon Jahner and Dr. Michael Dunn, Nutrition, Dietetics, and Food Science Introduction: Pregnant women who consume the recommended micronutrient level of folic acid can reduce the incidence of newborn neural tube defects (NTD), like spina bifida and ancelephthy, by up to 70% (Yang et al., 2002). Hispanic women with the highest rates of NTD births, […]
The Relationship Of Nd1 Mtdna Gene Polymorphisms To Energy Metabolism And Risk Of Obesity Among Peruvian Native Americans
Karen K. Thomas and Dr. Mark J. Rowe, Food Science and Nutrition INTRODUCTION Mitochondria are involved in the conversion of energy in the cell. Metabolic energy from the food we eat is converted in mitochondria to ATP by the electron transport system (ETS) and oxidative phosphorylation. The enzyme complexes involved in the ETS contain thirteen […]
Folic Acid Awareness among BYU Females
Natasha Bushnell & Mariana Chiriac with Nora Nyland, Food Science and Nutrition One of the B vitamins, folic acid is involved in DNA synthesis in the human body. This nutrient becomes crucial during the embrionic development of the fetus during a pregnancy. A maternal deficiency of folic acid, added to a genetic predisposition, has been […]
IDENTIFICATION OF A RAT GENE REGULATED BY DIETARY SELENIUM
Chris Cowdell, Departments of Food Science Nutrition/Molecular Biology Object Various genes have been discovered which are regulated by the dietary Intake of the trace element Selenium (Se).Some of these genes code for such enzymes as glutathione peroxidase (GP J Type I iodothyronine 5′ delodinase (IDI), and selenoproteln P (Se-P). GP, is an enzyme (a selenoenzyme) […]
Selenium Supplementation does not affect the Activity of the Enzyme 8-oxoguanine DNA Glycosylase
Benjamin J. Wycherly and Dr. Merrill Christensen, Food Science and Nutrition Highly reactive oxygen species produce DNA lesions, which are postulated to cause cancer. A particularly common lesion is that of an oxidized guanine residue, 8-hydroxyguanine (8-OHdG). This base is of particular concern because it can mispair with adenine during replication causing a mutation from […]
Selenium Regulation of NF-κB Binding in Cancerous Human Prostate Epithelial Cells
Wayne K. Nelson and Dr. Merrill Christensen, Food Science and Nutrition According to the National Cancer Institute, prostate cancer is the most frequently diagnosed nonskin cancer in men. In 1997 alone, it is estimated that 209,900 men were diagnosed as having the disease. Prostate cancer is also the second leading cause of cancer related death […]
