1 Chapter 20 Nutrition and Metabolism
2 Nutrients Nutrients are chemicals the body uses for growth, maintenance, and repair Essential nutrients: ones needed in the diet because the body cannot make sufficient amounts to meet body needs. There are six major types of nutrients: carbohydrates, lipids, proteins, minerals, vitamins, and water.
3 Healthy Eating 4 Cal/ gram for protein or carbohydrate 9 Cal/gram for lipids Experted-suggested dietary calories: 50-60% Calories from carbohydrate Should be <15% monosaccharides <30% from fats (mostly triglycerides) Should be < 10% from saturated fats 12-15% from protein
4 Guidelines for Healthy Eating Eat a variety of foods Maintain a healthy weight Choose foods low in fat, saturated fat, and cholesterol Eat plenty of fruits, vegetables, and grains Use sugars in moderation Use sodium in moderation: < 2.3 grams/day Use alcoholic beverages in moderation only: 1 drink/day for women; 2 drinks/day for men
5 My Pyramid Introduced in 2005 by USDA Web: Personalized approach to healthy food choices Based on gender, age, and activity Food from each of 6 bands needed each day Example: healthy, moderately active 18-year-old Female requires about 2000 Calories/day Male requires about 2800 Calories/day Steps a reminder of daily activity needed
6 My Pyramid
7 Categories of Nutrients Carbohydrates, proteins, lipids Calories for energy + building materials. Water Minerals Ca, P, K, S, Na, Cl, Fl, Mg, Fe, Cr, I, Mn, Co, Cu, Zn, Se. Table 21.1 Vitamins: essential or dietary provitamins Lipid-soluble: A, D, E, K Water-soluble: B vitamins and C Functions: Table 20.2
8 Categories of Nutrients: Six Carbohydrates, proteins, lipids Give calories for energy + building materials. Minerals: inorganic (Table 20.1) Ca, P, K, S, Na, Cl, Fl, Mg, Fe, I, Mn, Co, Cu, Zn, Se, Cr Electrolytes, components of skeleton, enzymes Vitamins: organic (Table 20.2) Lipid soluble: A, D, E, K Water soluble: B group, C Many function as coenzymes
9 Metabolism Facilitated by enzymes and coenzymes NAD + from B vitamin niacin FAD from riboflavin (B 2 ) Sequence of enzymatic steps is a pathway Two categories Anabolism: synthesis of more complex chemicals Catabolism: breakdown with energy release 40% cellular functions (ATP) 60% heat
10 Metabolism
11 Metabolism Interactions Animation Introduction to Metabolism You must be connected to the internet to run this animation.
12 Metabolism
13 Carbohydrate Metabolism Glucose: the body s preferred source for ATP production Possible uses of glucose Used immediately for ATP production Stored as glycogen in liver or skeletal muscle Leftover: forms triglycerides in adipose tissue Enters cells by facilitated diffusion Insulin increases rate of transport
14 Glucose Catabolism Overall catabolism of glucose Glucose + 6 O ATP + 6 CO H 2 O 1. Glycolysis (in cytosol) Glucose pyruvate + ATP + NADH + H + Anaerobic cellular respiration 2. Transition step (in mitochondria): Pyruvate acetyl CoA + CO 2 + NADH + H + 3. Krebs cycle (in mitochondria): aerobic CO 2 + ATP + NADH + H + + FADH 2 4. Electron transport chain (in mitochondria): aerobic NADH + H + + FADH 2 + O 2 ATP + H 2 O
15 Glucose Anabolism and Regulation of Blood Glucose Levels When blood glucose is high Glucose + ATP glycogen (in liver, muscle) Effect: blood glucose level is lowered When blood glucose is low Hormones glucagon and epinephrine stimulate Glycogen breakdown to glucose Hormones: glucagon and cortisol stimulate Gluconeogenesis in liver cells by Glycerol (from fat) glucose Some amino acids glucose
16 Glucose Anabolism and Regulation of Blood Glucose Levels
17 Lipid Metabolism Lipolysis (catabolism): triglycerides glycerol + fatty acids Glycerol glycolysis or gluconeogenesis Fatty acids acetyl-coa (2-carbon) Krebs cyle ATP Liver converts some acetyl-coa ketone bodies Diabetics can form excessive ketone bodies acetone (causes sweet breath) + acidosis (with possible coma and death) Lipogenesis (anabolism) Excess fats, carbohydrates, or proteins fats
18 Lipid Metabolism
19 Lipid Transport in Blood Lipids are not water soluble so need protein coating lipoproteins Types of lipoproteins Chylomicrons: carry dietary fat to adipose Very low-density lipoproteins (VLDL) Made in liver; transport fat to adipose tissue Converted to LDLs Low-density lipoproteins (LDL): bad Carry 75% of cholesterol to cells for use there High-density lipoproteins (HDL): good Remove excess cholesterol and transport to liver for disposal
20 Protein Metabolism Catabolism: protein breakdown Deamination in liver to remove NH 2 NH 3 Liver converts toxic NH 3 urea urine Rest of amino acid Krebs cycle ATP Anabolism: protein synthesis to form many different proteins in the body Essential amino acids (10): must come in diet Nonessential amino acids (10): can be made in the body by modifications of essential amino acids
21 Metabolism and Body Heat Gain Heat is one form of energy Measured in calories 1 calorie (cal) = energy needed to raise 1 g of water 1 o C For foods use kilocalories (1000 cal) = Calorie Heat is produced (gained) from catabolism Rate of production = metabolic rate Basal metabolic rate (BMR) = heat produced from catabolism when resting and fasting BMR for adult : Cal/day
22 Metabolism and Body Heat Metabolic rate is affected by the following Exercise: rate can increase times Hormones: thyroid is primary Nervous System: ANS can increase Body temperature: warming increases Ingestion of food: gives 10-20% increase Age: metabolic rate of child higher than adult s Gender, pregnancy, climate, sleep, malnutrition
23 Body Heat Loss Must be continuous as catabolism constantly produces heat Routes of heat loss Radiation: loss of body heat to air Conduction: loss of body heat to surface, such as cold metal seat Convection Loss of body heat to air moving from a fan or from breeze outside shower curtain Evaporation Conversion of water to vapor as in sweating; helps prevent overheating with exercise
24 Control of Body Temperature Balance regulated by hypothalamus Detects changes in temperature ( thermostat ) Warming mechanisms Sympathetic vasoconstriction heat loss Epinephrine metabolism Increased muscle tone metabolism Can lead to shivering heat from muscles TSH thyroid gland thyroid hormone in blood metabolism Cooling mechanisms The reverse + sympathetic-stimulated sweating
