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.
Essential amino acids are those that you must consume in your diet because your body cannot make them. Nonessential amino acids are those that your body can produce, so they are not as vital in the diet. The way the amino acids come together determines what type of protein is made.omplement Proteins. Complement proteins are two or more incomplete protein sources that together form a complete protein. If a protein is low in a certain amino acid, like lysine, a complement protein is one that provides the missing protein, in this case lysine.
