Proteins
Molecules with the same molcular formulae but differing structural formulae are called isomers.
Biological molecules are primarily joined by covalent bonds.
If molecules are outer space, they have no forces (gravity) to move them around, hence that is why they stay togethor i.e. in a structural arrangement of a solid state.
Structural formulas are used primarily for organic compounds for which molecular formulas correspond to more than one isomer, or for chemical discussions in which the shapes of molecules are important, such as crystallography.

tendons
Muscles are attached by tendons and ligaments to bones.
Tendons attach muscles to bones.
Tendons are attached to muscles.
Muscles are attached to tendons ( a dense connective tissue) which are then attached to Bones. Muscles -> Tendons -> Bones
Tendons
Tendons connect muscle to muscle and also muscle to bone.
Muscles are connected to bones by tendons.
