Study Notes
Carbohydrates
- Carbohydrates are generally white solids.
- Most carbohydrates are soluble in water, but some polysaccharides are not.
- Carbohydrates are a major source of energy.
- Carbohydrates make up 55% of our daily calorie intake.
- 1 gram of carbohydrates provides 4 calories.
Globins
- Rich in histidine, but are not basic.
- Globins unite with heme to form hemoglobin.
- Differences in hemoglobin between species are primarily due to differences in globin, while the heme portion remains the same.
Retention of Ions
- Aldosterone causes the retention of sodium (Na+), potassium (K+), chloride (Cl‾), and magnesium (Mg++).
