The sharing of electrons in alcohol as an example, are much more losely bound; this is a common way that organic compounds are formed, and why organic reactions can proceed at lower temperatures, mediated by enzymes. No enzyme could break down NaCl alone to make pure sodium metal and chlorine gas.
Protein can be categorized into two types: complete and incomplete proteins. Proteins are made up of smaller units, called amino acids. Complete proteins contain all of the amino acids your body needs and include meat, fish, poultry, dairy, and soy products.
The four structure types are primary, secondary, tertiary, and quaternary structure. A protein's structure determines its function. For instance, structural proteins such as collagen and keratin are fibrous and stringy.Globular proteins like hemoglobin, on the other hand, are folded and compact. Hemoglobin, found in red blood cells, is an iron containing protein that binds oxygen molecules.hen a number of amino acids are linked together by peptide bonds, a polypeptide chain is formed. One or more polypeptide chains twisted into a 3-D shape forms a protein.
