To make a protein, amino acids are linked together in a long chain. The chain is then bundled into to a three-dimensional structure, like a tangled ball of yarn. Although there are hundreds of different amino acids, only 21 are used in animal proteins.

Proteins are the essential building blocks of all tissues and organs of the body including:
Proteins are often described as the 'backbone' of cells because they have a structural role in all cell walls. Proteins are required for all tissue growth, replenishment and repair.
Young pets may need several visits in their first year for vaccinations. Adult pets generally benefit from annual check-ups, while senior or special-needs pets might require more frequent visits.
If there is more protein available than necessary for building blocks, proteins may also be used as a source of dietary energy.
