Facts about Protein
- 10
A single egg white contains approximately 3.6 grams of protein with all nine essential amino acids, making it one of nature's most complete protein sources for human nutrition.
- 09
Lactase, the enzyme that breaks down milk sugar in infants, stops being produced in 65 percent of humans after age four due to genetic lactose intolerance.
- 08
Enzymes, which are catalytic proteins, can increase the rate of chemical reactions by up to one million times, allowing metabolic processes to occur fast enough to sustain life.
- 07
Antibodies, a specialized class of proteins called immunoglobulins, can recognize and bind to over one billion different foreign antigens, enabling your immune system to fight virtually any pathogen.
- 06
Prions, misfolded proteins linked to diseases like Creutzfeldt-Jakob disease, can cause normal proteins to misfold in a chain reaction, making them infectious agents without containing any DNA or RNA.
- 05
Collagen comprises approximately 30 percent of all protein in the human body and provides structural support to skin, bones, tendons, and ligaments throughout life.
- 04
Hemoglobin, the iron-containing protein in red blood cells, carries approximately 270 million oxygen molecules per single cell throughout your body.
- 03
Muscle tissue requires approximately 1.6 grams of protein per kilogram of body weight daily for athletes engaging in resistance training to maximize repair and growth.
- 02
In 1955, Frederick Sanger became the first person to sequence all 51 amino acids in insulin, earning him the Nobel Prize for this groundbreaking protein mapping achievement.
- 01
The human body contains approximately 20,000 different proteins that are built from just 20 amino acids combined in varying sequences.
