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.
Protein serves both structural and functional roles in the human body. Different types of protein are involved in building up the structure of the human body eg. Actin and myoâ¦sin ( two proteins ) make muscle cells, keratin makes hair, etc. Proteins serve structural roles by being a component of the cells.
