The element present in all large macromolecules in the human body is carbon. Carbon is fundamental to the structure of carbohydrates, proteins, lipids, and nucleic acids, as it forms the backbone of these molecules. Its ability to form stable bonds with various elements allows for the complex structures necessary for biological functions.
Iron. It is there in grams. Iodine is there in milligrams.
Cadmium is a poisonous chemical which in large concentrations can cause respetory problems, kidney failure and the softening of bone material.
A semipermeable membrane is a large glucose molecule that requires facilitated diffusion but an oxygen molecule does not.
They are called a molecule.A compound is a chemical combination of two or more elements. However, a molecule can consist of two or more atoms of the same element (e.g. ozone is a molecule formed of three oxygen atoms).
Diamond is made up of pure carbon. Here one carbon atom is attached to other four carbon atoms. So diamond should be called as molecule. Should be! If it is called as molecule, then it will be too large a molecule. It will be interesting to count the number of atoms in a big diamond. It will not be possible for the human brain to understand such a very high number.

Carbon and/or hydrogen.
molecule
By definition, an element is a single atom, not a molecule.
Proteins
Plastic is a large molecule called a polymer, and it's always a compound.
Iron. It is there in grams. Iodine is there in milligrams.
All the macromolecules in the human body are basically Carbon covalently bonded to other elements- mostly Hydrogen, Oxygen and other carbon atoms. There are other elements, but they don't appear in all of the body's macromolecules.It is Carbon.
Zinc is a trace element as the others are found in large amounts.
Cesium is largest element on the periodic table.The atomic radius of Cs is around 273pm. It is present at the lower left corner of the table.
There are three elements. They are C,H and O
