A bond in which valence electrons are shared is called covalent. is the process of breaking large molecules into smaller ones by adding water. If energy is released when a molecule is broken apart, it is a(n) reaction. The process of building up large molecules from small components is a(n) process. A lipid with four sites lacking hydrogen saturation is a lipid.

A bond in which valence electrons are shared is called COVALENT.

HYDROLYSIS is the process of breaking large molecules into smaller ones by adding water.

If energy is released when a molecule is broken apart, it is an EXERGONIC REACTION.

The process of building up large molecules from small components is an ANABOLIC process.

A lipid with four sites lacking hydrogen saturation is a POLYUNSATURATED lipid.
