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.
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.
