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.
Humans have tens of thousands of different proteins, each with a specific structure and function. Proteins are the most structurally complex molecules known. Each type of protein has a complex three-dimensional shape or conformation. All protein polymers are constructed from the same set of 20 amino acid monomers. Polymers of proteins are called polypeptides. A protein consists of one or more polypeptides folded and coiled into a specific conformation. Amino acids are the monomers from which proteins are constructed. Amino acids are organic molecules with both carboxyl and amino groups. 1  At the center of an amino acid is an asymmetric carbon atom called the alpha carbon. 2  Four components are attached to the alpha carbon: a hydrogen atom, a carboxyl group, an amino group, and a variable R group (or side chain).
