The smaller unit molecules which combine to form proteins and polypeptides are called amino acids. The amino acids are joined to each other by peptide bonds.
Amino acids by (mostly linear) peptidic bonding
"amino acids"
Amino acids
Proteins are broken down firstly into peptides, which are then digested into even smaller units - amino acids.
Proteins are made from long chains of smaller molecules called amino acids. Amino acids are biologically important organic compounds that are composed of amine and carboxylic acid.

The first product of proteins digestion are polypeptides.
Cleaves proteins into smaller polypeptides
No. Polypeptides and polysaccharides are two different types of macromolecules. The first class is commonly called "proteins" and the second is commonly called "sugars." Both are polymers - molecules that are composed of smaller subunits called monomers. Polypeptides ― or proteins ― are composed of monomers called amino acids. In contrast, polysaccharides are composed of monomers called monosaccharides.
Proteins are long chains of amino acids. Smaller chains of amino acids are known as polypeptides. (Proteins are still polypeptides).
enzymes breaks down food proteins into smaller molecules that can be carried by blood
Addition and polymerization will combine smaller molecules together to create a larger one.
Amino acids by (mostly linear) peptidic bonding
They are complex molecules made from smaller molecules.

That happens all the time. Smaller molecules combine to form larger molecules; larger molecules break up into smaller molecules.
