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.
You may think of protein as the muscle-building nutrient and fat as the fat-storage nutrient, but protein can act as a fat under certain physiological conditions. Proteinâs primary role is to provide the building blocks, or amino acids, to synthesize structural and functional proteins within the body.
