What is a Primitive Solid? A primitive solid is a âbuilding block' that you can use to work with in 3D. Rather than extruding or revolving an object, AutoCAD has some basic 3D shape commands at your disposal. From these basic primitives, you can start building your 3D models.
Fats typically provide more than half of the body's energy needs. Fat from food is broken down into fatty acids, which can travel in the blood and be captured by hungry cells. Fatty acids that aren't needed right away are packaged in bundles called triglycerides and stored in fat cells, which have unlimited capacity.
As the primary source of energy for the body, carbohydrates play a role in regulating fat and protein metabolism. With a sufficient supply of carbohydrates to meet the general needs of the body, it will not have to use protein and fat for energy. Protein will serve its primary purposes of tissue growth and repair.
