The organic material in coal is composed mainly of carbon, oxygen, hydrogen, nitrogen, and sulfur. The heat of metamorphism destroys the organic molecules of coal, volatilizing the oxygen, hydrogen, nitrogen, and sulfur. What remains is a nearly pure carbon material that crystallizes into mineral graphite.
Egg White Nutrition Basics. According to the Egg Nutrition Center (ENC), the average egg contains about 6.29 grams of protein, 3.6 of which come from the egg white. In addition to proteins, other nutrients found in the egg white are riboflavin, niacin, folate, vitamin B12, calcium, iron, copper, zinc and sodium.
Most nutritionists agree that having protein in your morning meal is the best way to start the day. There are roughly 6 grams of protein in a single egg. One egg also weighs about 1.6 ounces, so ounce for ounce eggs are considered high in protein. If you donât eat meat or if you eat limited meat, eggs are a great way to get the protein your body needs to stay healthy and strong.
