OEE: Let's move to more examples where lean tools work great; OEE (Overall Equipment Effectiveness) is a great example to demonstrate that, in our industry, there are areas that should leverage OEE as an equipment performance metric, and where OEE does not add value.
Making the world better, one answer at a time. The seven protein classes are structural proteins, storage proteins, defensive proteins, transport proteins, signal proteins, contractile proteins, and enzymes.
Proteins are macromolecules and have four different levels of structure â primary, secondary, tertiary and quaternary. There are 20 different standard L-Î±-amino acids used by cells for protein construction. Amino acids, as their name indicates, contain both a basic amino group and an acidic carboxyl group.
