Chapter 6 – Proteins and Amino Acids 6.1 Proteins in Our Food  Legumes – starchy seed of a plant that produces bean pods; includes peas, peanuts, beans, soybeans, and lentils o Important source of dietary protein  Amino Acids – building blocks of proteins. Each amino acid contains an amino group, an acid group, and a unique side chain o Proteins in plants made up of combinations of these therefore plant proteins not used as efficiently as animal proteins 6.2 The Structure of Amino Acids and Proteins Amino Acid Structure  Each amino acid consists of central C that is bound to H atom, amino group, acid group, side chain o Nitrogen in amino acids distinguishes protein from CHO and fat o Side chains give amino acids their unique properties  9 must be consumed in diet  Essential Amin Acid (Indispensable Amino Acid) – amino acid that cannot be synthesized by the body in sufficient amounts to meet its needs and therefore must be included in the diet  The other 11 AA commonly found in protein are nonessential, or dispensable, amino acids because they can be made in the body. o Some of them cannot be synthesized at certain times, therefore called conditionally essential amino acids  Phenylketonuria – genetic disease in which amino acid phenylalanine cannot be metabolized normally, causing it to build up in the blood. If untreated, condition results in brain damage Protein Structure  Amino acids linked together by peptide bonds, which join acid group of one amino acid to the amino group of another amino acid  Polypeptide – chain of amino acids linked by peptide bonds that is part of the structure of a protein  Denaturation – alteration of a protein’s 3-dimensional structure 6.3 Protein Digestion and Absorption  Proteins must be digested before their amino acids can be absorbed into the body  (p. 162 detailed figure on digestion and absorption) KNOW FOR TEST! 6.4 Protein Synthesis and Functions  Amino Acid Pool – all the amino acids in body tissues and fluids that are available for use by the body Synthesizing Proteins  Genes – length of DNA that contains the info needed to synthesize a polypeptide chain Regulating protein synthesis  Both types of proteins made and when they are made are carefully regulated by increasing and decreasing gene expression. Limiting amino acids  Transamination – process by which an amino group from one amino acid is transferred to a carbon compound to form a new amino acid  Limiting Amino Acid – essential amino acid that is available in the lowest concentration relative to the body’s need 6.5 Protein in Health and Disease Protein Deficiency  Protein-Energy Malnutrition (PEM) – condition characterized by loss of muscle and fat mass and increased susceptibility to infection that results from the long-term consumption of insufficient amounts of energy and/or protein to meet the body’s needs  Kwashiorkor – form of protein-energy malnutrition in which only protein is deficient  Marasmus – form of protein-energy malnutrition in which deficiency of energy in the diet causes severe body wasting Proteins and Food Allergies and Intolerances  Food Allergy – adverse immune response to a specific food protein  Food Intolerance or Food Sensitivity – adverse reaction to a food that does not involve the production of antibodies by the immune system  Celiac Disease – disorder that causes damage to the intestines when the protein gluten is eaten 6.6 Meeting Protein Needs Balancing Protein Intake and Losses  Nitrogen Balance – amount of N consumed in the diet compared with the amount excreted over a given period Choosing Protein Wisely  Protein Complementation – process of combining proteins from different sources so that they collectively provide the proportions of amino acids required to meet the body’s needs Vegetarian Diets  Vegetarian Diets – diet that includes plant-based food and eliminates some or all foods of animal origin  Vegan Diet – plant-based diet that eliminates all animal products
