noun
- Plural of myoglobin; iron-containing proteins found in muscle cells that bind and store oxygen, giving muscle tissue its red color.
Usage: technical/scientific; typically used in biochemistry and physiology contexts
Examples
- Myoglobins in red muscle fibers help endurance athletes maintain aerobic performance.
- The concentration of myoglobins is higher in deep-sea diving mammals than in terrestrial animals.
- Biochemists study myoglobins to understand how oxygen is transported and stored in muscle tissue.
- Dark meat in poultry contains more myoglobins than white meat, which is why it appears darker.
- Athletes with higher myoglobin levels in their muscles typically have better oxygen utilization during exercise.
