Proteins are essentially amino acids and polypeptide bonds formed from a set of 20 amino acids. With that being said, amino acids consist of:
A central alpha Carbon atom which has 4 bonds:
One hydrogen bond
Amino group (two hydrogens attached to a nitrogen)
Carboxyl Group (Another Carbon double bonded to oxygen and single bonded to a hydroxide group [Oxygen and Hydrogen])
And an R group. The R group is what makes the amino acids different and function different such as making it non-polar, polar, or electrically charged (acidic or basic).
Up to uranium elements are made by stellar nuclear synthesis; after uranium elements are man made.
An atom is the basic particle from which elements are made :D
what is made up of two or more elements
All the existing elements are natural the man made elements are rare and have a very short life.
Yes, they are true chemical elements but man made.

Everything is made from elements except elements themselves.
Everything in the world is made from elements.
All elements are made of atoms.
Fibers can be made out of several elements.
Elements are not made of other elements. They are made of protons, neutrons, and electrons. They all differ in configuration.
Man-made elements are made in a particle accelerator.
Chemical compounds are formed from chemical elements.
Two or more elements.
Elements are not made of other elements. They are made of protons, neutrons, and electrons. They all differ in configuration.
They are related because atoms are made of matter,elements are made of atoms,and matter is made up of elements.
