HNF 150 Study Guide - Quiz Guide: Essential Amino Acid, Vitamin K, B Vitamins
Document Summary
Study guide: describe the general structure of proteins and the three components of amino acids: protein contains carbon, hydrogen, oxygen, and nitrogen (unlike carbs and lipids). The structure of proteins are amino acids linked together by peptide bonds in long chains/ amino acids are building blocks of proteins. Amino acids have a backbone made of an amine group (contains nitrogen), an acid group, and a side chain. The side chain differs in size, shape, and electrical charge. 7 roles of proteins in the body: supporting growth and maintenance structural proteins- proteins in our bones, muscle, skin, building enzymes, hormones and other compounds i. enzymes speed up reactions in the body ii. Single aa"s as components of other compounds ex: niacin. Transport and recognition proteins i. lipoproteins: moves to cells ii. Active transport: when we are absorbing something into cells it is mediated by proteins on the surface of cells.
