Amino acids are molecules that combine to formproteins. Amino acids and proteins are the building blocks of life.
When proteins are digested or broken down, amino acids are left. The human body uses amino acids to make proteins to help the body:
Amino acids can also be used as a source of energy by the body.
Amino acids are classified into three groups:
ESSENTIAL AMINO ACIDS
NONESSENTIAL AMINO ACIDS
Nonessential means that our bodies can produce the amino acid, even if we do not get it from the food we eat. Nonessential amino acids include: alanine, arginine, asparagine, aspartic acid, cysteine, glutamic acid, glutamine,glycine, proline, serine, and tyrosine.
CONDITIONAL AMINO ACIDS
You do not need to eat essential and nonessential amino acids at every meal, but getting a balance of them over the whole day is important. A diet based on a single plant item will not be adequate, but we no longer worry aboutpairing proteins (such as beans with rice) at a single meal. Instead we look at the adequacy of the diet overall throughout the day.
