Amino Acids


Lysine is an amino acid with a side chain higher polar which become highly hygrophilous. Lysine has a positive charge in a neutral pH. The side chain of Lysine and arginine are the longest in all amino acids. Lysine helps in bone growth and in the formation of collagen, besides that is one of the bones, cartilage and other connective tissues. The use of Lysine is very common as a feed grade additive, it works as a limiting in the growth of pigs and very important in poultry farming.

Threonine is one of the amino acids that is coded by genetic code, being one of the protein components of living being. Threonine has two asymmetric centers in carbon 2 and 3. The configuration of carbon 2 is S and carbon 3 is R.
Threonine is the most abundant essential amino acid to immunoglobulin protein.
Experimentally, it has been shown in growing pigs and in pig gilts that poor diet in threonine leads to a low plasma concentration of IgG. There are experimental evidences that threonine is related to the maintenance of the specific gut wall immunity.
CAS n.º : 72-19-5



Betaine is an N-trimethylated amino acid. It is a natural product which has the important function not only in the plant metabolism, but also in animal. One of the most common Betaine is a derivate of glycine in which tree groups of methyl are connected to the nitrogen atom of glycine molecule.
This betaine compound is normally called glycine betaine or trimethylglycine. They are also betaines: alanine betaines, proline betaines and histidine betaine.
