Protein

Protein's the second most abundant substance in the body (second only to water) and with functions as varied as providing structure and repair (& growth) of tissue (skin, bone, MUSCLE), to preventing and fighting infection, protein is suitably named (from the Greek word meaning "of first importance").

Proteins are made up of smaller sub-units called Amino Acids, which I'll post about tomorrow :-).
