The atoms present in a protein molecule are bonded to each other by covalent bonds.

A special amide bond called a peptide bond binds the amino acid subunits together and in a folded protein you will get hydrogen bonds, hydrophyllic bonding, hydrophobic bonding and covalent sulfur-sulfur bonding to name several types.
The four different types of protein structures are determined by the interactions between amino acid residues in the polypeptide chain. These structures are held together by different types of bonds: primary structure by peptide bonds, secondary structure by hydrogen bonds, tertiary structure by disulfide bonds, hydrogen bonds, ionic bonds, and hydrophobic interactions, and quaternary structure by the same bonds as tertiary structure.
The types of bonds that hold the 3D shape of a protein together are primarily hydrogen bonds, ionic bonds, disulfide bonds, and hydrophobic interactions. These bonds contribute to the stability and structure of the protein molecule.
Non-covalent bonds such as hydrogen bonds, van der Waals interactions, ionic bonds, and hydrophobic interactions are disrupted when a protein is denatured. These bonds are responsible for maintaining the protein's specific three-dimensional structure and functionality.
Primary, tertiary and quaternary levels of protein structure.
The three types of chemical bonds that cross-link protein strands in hair are disulfide bonds, hydrogen bonds, and salt bonds. Disulfide bonds are the strongest and most permanent, while hydrogen bonds and salt bonds are weaker and can be broken by water or heat.
Protein molecules have covalent bonds in them, and there are hydrogen bonds that act as intermolecular bonds.
Proteins are made up of amino acids, which are linked together by peptide bonds. The number of bonds in a protein structure can vary depending on the amino acid sequence and the folding pattern of the protein. However, the main type of bond in a protein structure is the peptide bond.

Proteins are made from amino acids connected by peptide bonds (a type of amide bond).
Peptide bonds are the type of bonds that form chains of amino acids in a protein. Peptide bonds are covalent bonds that link the carboxyl group of one amino acid to the amino group of another amino acid. These bonds are formed through a condensation reaction between the two amino acids.
Many enzymes consist of a protein and a non-protein (called the cofactor). The proteins in enzymes are usually globular. They have tertiary structure and this type of globular protein includes immunoglobins, as well. The structures are held in place by hydrogen bonds, disulfide bridges and ionic bonds.
Protein shape is determined by the type and sequence of the amino acids that make it up. The bonds between the amino acids caused the protein chain to bend in specific ways.
Quaternary structure. This structure results from the assembly of multiple polypeptide chains to form a functional protein complex. The individual chains in the complex can interact through various types of bonds, such as hydrogen bonds, disulfide bonds, and hydrophobic interactions.
Peptide bonds
Disulfide bonds between cysteine amino acids in a peptide chain are critically in stabilizing preferred secondary and tertiary structures. Many enzyme activities rely on specific shapes that are stabilized by these disulfide bonds.
Non-covalent bonds such as hydrogen bonds, van der Waals interactions, ionic bonds, and hydrophobic interactions are disrupted when a protein is denatured. These bonds are responsible for maintaining the protein's specific three-dimensional structure and functionality.
