Study Notes
Heat Loss in Humans
- When skin temperature is greater than the environment temperature, radiation is the major mode of heat loss.
Amino Acids
- Selenocysteine is determined as the 21st amino acid.
Sickle Cell Disease
- Sickle cell disease results from a missense mutation in both genes encoding for the beta-chain, resulting in a change from Glutamate to Valine.
Collagen Fiber Defects
- Defects in Type IV collagen fiber are associated with a condition causing gross hematuria, elevated blood pressure, and decreased urine output, accompanied by bilateral hearing loss and opacification of the lenses.
Glucose Uptake
- Insulin-stimulated glucose uptake involves the GLUT4 transporter.
Macronutrient Distribution
- The acceptable macronutrient distribution range (AMDR) of simple sugars is not specified, but the exact range is an important concept in nutrition.
