NUTR 200 Lecture Notes - Lecture 11: Essential Amino Acid, Nutrigenomics, Protein Structure
Document Summary
Idenify the two main steps in protein synthesis. Describe how proteins are digested and absorbed by the body. List some diferent funcions of proteins in the body. Nutriion and geneics: genotype = collecion of genes inherited from parents, mutaions = alteraions in gene sequence. Results in changes in primary structure of a given protein. Are there changes that don"t alter the gene sequence: epigeneic changes = altered regulaion of gene expression. How much protein synthesis from that gene: nutriional status and certain nutrients are known to be involved in epigeneic changes, nutrigenomics = emerging ield aimed at understanding interacions between nutriion and gene expression, goals . Provide the 9 essenial amino acids and non-essenial amino acids too. For protein synthesis, all essenial amino acids must be available. Hcl - breaks down protein structure (denatures) acivates pepsin. Pepsin - an enzyme that breaks down proteins into short polypepides and amino acids.
