Document Summary

For each of these three categories, there"s only a small number of atoms that are involved. For fats, its also carbon, hydrogen, and oxygen. And one nitrogen atom is added for the amino acids or the protein materials, namely the linkage of amino acids together. O-h groups that you see are important parts of a carbohydrate unit because it means that they generally can be soluble in water. We"ve already examined the micronutrients, those nutrients that are there in small quantities relative to what we traditionally call the macronutrients, the fats, carbohydrates, and proteins. Fats at 65 grams a day, protein at about 60, complex carbohydrates, like starches, 240, and sugar around 50, totalling about 415 grams per day. This amounts is (to a little less than one pound) for the north american audience. Here are the materials themselves displayed in the sense of protein;
