Egg whites are often referred to as the perfect protein, due to their amino-acid makeup and the body’s ability to utilize them properly. The average large, whole egg contains about 72 calories, 6 g of protein, 5 g of fat, about 200 mg of cholesterol, and nearly no carbs. The average large egg white contains only 17 calories, 4 g of protein, and no carbs, fat, or cholesterol. Egg whites contain as many as 40 different proteins. Of these, ovalbumin constitutes the majority, making up about 55 percent of the protein in egg white. Ovotransferrin is an iron-binding protein in egg whites that provides antimicrobial properties and makes up over 10 percent of the protein content. Ovomucin is another type of protein that makes up less than 5 percent of egg-white protein and provides the jellying property of egg white, as well as antimicrobial properties. Egg-white protein is rich in BCAAs and arginine, as well as the sulfur-containing amino acids cysteine and methionine. These amino acids are critical for maintaining the structure of many proteins such as collagen, which is critical for maintaining joint health and levels of certain hormones. To read more click here!
