All lipids are made up of the same atoms: carbon (C), hydrogen (H) and oxygen (O). Lipids contain the same elements that make up carbohydrates but in different proportions. Lipids have a large proportion of carbon and hydrogen bonds and a small proportion of oxygen atoms. Although the st...
Medium-carbon steel is made up of iron and a slew of other alloying elements, and in some places, you’ll hear it referred to as M2 steel. A closer look at its makeup and you’ll see that its carbon concentration ranges between 0.30% and 0.60% and its manganese between 0.60% and 1....
