That sounds like an ineffective method to strip zinc from steel because the zinc plating is thin, and the steel will remain wetted with it; plus, it's possibly dangerous, environmentally questionable, and expensive :-).Opinion!f the plating is not defective, I think it can be a good base for the e-coating, and will offer sacrificial protection. If you remove the e-coating, you will have to phosphatize the surfaces before e-coating. Good luck.
Fat has the most calories of all the nutrients: 9 calories per gram. In a healthy diet, about 30 percent of total daily calories should come from fat. This means eating about 50 to 80 grams of fat each day. Fat gives the body energy, too, but the body changes only about 10 percent of fat into glucose. By itself, fat doesn't have much impact on blood sugar. But when you eat fat along with a carbohydrate, it can slow the rise in blood sugar.
The nutrients protein, carbohydrates, and fats in food serve as the body's energy sources. 1  Each gram of protein and carbohydrate supplies 4 calories, or units of energy.  Fat contributes more than twice as much: 9 calories per gram.
