Product Name:L Isoleucine
CAS No.:73-32-5
Appearance:White powder
MF:C6H13NO2
Purity: 99% Min
Isoleucine powder, an amino acid that is produced when the majority of common proteins are hydrolyzed. One of the so-called essential amino acids for rats, birds, and humans, it is one of the first amino acids to be discovered (1819), and it is found in muscle fiber and wool.
Leucine isoleucine and valine powder is also present in large quantities (about 15%) in hemoglobin, the oxygen-carrying pigment of red blood cells.i.e., they need food sources because they can’t make it. L isoleucine powder is made in plants and microorganisms from pyruvic acid, which is a byproduct of the breakdown of carbohydrates.

Van Milguen et al. (2012) conducted an extensive meta-analysis study on isoleucine powder to determine the need for this amino acid: diets containing blood meal or blood cells were shown to have a higher need for leucine isoleucine and valine powder.
This is because they are rich in leucine, and excess leucine activates the metabolic pathway that breaks down l isoleucine powder. On the other hand, when this type of feedstock is not used, the requirement ratio of isoleucine to lysine is 53%.
