Document Summary

Lecture 6 chapter 6 protein: amino acids. Nutritional genomics examines the interaction of genes and nutrients. These interactions include nutrigenetics and nutrigenomics: nutrigenetics: examines how genes influence the activates of nutrients, nutrigenomics: includes epigenetics, examines how nutrients influence the activates of organs. Methylatio(cid:374), acetylatio(cid:374) : epigenetics - the ability of environmental factors to influence gene expression without changing the. Mice stuff: there are multiple genes that cause obesity. Influence of several genes ie high ldl depends on many genes: sensitive to interactions with the environment eating pufas, single nucleotide polymorphisms (snps) can affect lipid metabolic pathways. Proteins are made up of 20 amino acids and are a major source of dietary nitrogen. All amino acids have a similar structure, except that they differ in their side chains. Proteins must first be digested to amino acids, which are then absorbed and repackaged into proteins as needed. Proteins are involved in most bodily functions.
