The following are the first 14 atoms from the protein 1CRN:

These fourteen atoms are members of two THR residues.

Can the information regarding atomic bonds be interpreted only from these fourteen lines? Or do I have to use my background knowledge of amino acids to find bonds?

Note: I am not talking about hydrogen bonds. I am talking about atomic bonds only in the atoms in the residue.
