2. Structure of Collagen Also, with the structure of the amino acids, which show them in a monomer form but when they become polymers; Hydrogen bonding takes place, between the Oxygen and the Hydrogen. Collagen fibres, with the main amino acids. Bonds which Open up Hydrogen Bonding Between Oxygen and Hydrogen

3. Hydrogen Bonding This structure is showing the hydrogen bonds in the collagen atom. Here is the molecular formula: C2H5NOC5H9NOC5H10NO2. This is also the structural formula of Collagen.

4. Bond dissociation enthalpies The hydrogen bonds come from the peptide (short polymers of amino acids) NH groups of the glycine. The enthalpy for this −393.7 ± 1.5 kJ/mol The enthalpy for the intermolecular bonds is 70 J/g.

9. Collagen: An image! A structural image of Collagen Collagen products, (industrial use) These are products which contain Collagen and propose they benefit anyone who takes them to give them rejuvenated and younger skin.
