Study Notes
Carbohydrates
- Primary fuel source for all body cells is glucose.
- Types include monosaccharides (simple sugars) and polysaccharides (like starch and glycogen).
Lipids
- Major component of the diet classified as neutral fats (triglycerides).
- Cholesterol, found in lipids, is essential for steroid hormone and cell membrane formation.
Proteins
- Composed of amino acids, which are necessary for various biological functions.
- Complete protein sources include eggs, milk, meat, and fish.
Vitamins and Minerals
- Essential nutrients needed for various biochemical processes, often functioning as coenzymes.
- Main sources are vegetables, legumes, milks, and some meats.
Energy Measurement
- Energy value of food is measured in kilocalories (kcals) or calories.
Major Nutrients
- Carbohydrates, proteins, and lipids are regarded as major nutrients necessary for bodily functions.
Body Weight Maintenance
- To maintain body weight, energy intake from food must equal energy expenditure by the body.
Gluconeogenesis
- Process of producing glucose from non-carbohydrate sources, such as amino acids and fats.
- Occurs in response to low blood glucose levels.
ATP Production
- Glucose is the preferred fuel for most body cells to produce ATP (adenosine triphosphate).
Glycogen Storage
- The liver is responsible for manufacturing and storing the majority of the body’s glycogen.
Hormonal Regulation
- Thyroxine is the hormone supplement that can improve conditions like hypothyroidism.
Metabolism
- Refers to all chemical reactions necessary to sustain life, including energy production and utilization.
Lipoproteins
- Low-density lipoprotein (LDL) is responsible for transporting cholesterol and other lipids to body cells.
Total Metabolic Rate (TMR)
- Defined as the total kilocalories the body needs to fuel ongoing activities, notably rising during physical exertion.
Anabolism
- The metabolic process where larger molecules or structures are synthesized from smaller ones.
Energy Balance
- Energy balance occurs when energy intake equals total energy output; disruptions may lead to weight gain or loss.
- True statements about energy balance include an increase in energy intake with food consumption and that energy output comprises heat and work.
Ketoacidosis
- A condition resulting from the incomplete breakdown of fats, leading to acidification of blood.
