Types Of Amino Acids, Their Characteristics And Where To Find Them
There are several types of amino acids, all of which play an important role in bodily functions. These nutrients are one of the essential components of proteins and are known for their role in protein construction and the synthesis of hormones and neurotransmitters.
In particular, these are molecules with an amino group at one end, and another carboxyl at the opposite side. In the body they join in more or less long chains to form the body’s proteins. They also degrade to other components that can be used as an energy source. Are you interested in knowing more?
Types of amino acids
There are hundreds of amino acids in nature, although the human body only needs 20 to form its structures. They can be classified in several ways: according to the properties of their side chain, by the position of the amino group or by the method of production. Regarding the latter, there are 3 types.
1. Essential amino acids
Essential amino acids are those that the body cannot manufacture on its own. Consequently, they have to come from food. If they are not provided through the diet, there is a deficit that can have health consequences. In total, it groups the following varieties:
Leucine.
Isoleucine.
Valine.
Methionine
Lysine
Phenylalanine
Tryptophan
Threonine
Histidine.
Arginine
When a food has all these essential amino acids, and in the amounts required by the body, it is considered a protein of high biological value. On the contrary, if any are missing or present in small quantities, it is said that it is a limiting amino acid that has to be provided by another source throughout the day.
