Role of Amino Acids in Poultry

Role of Amino Acids in Poultry

Methionine

Methionine not only serves as a constituent of body protein but also is involved in the development of the digestive tract and growth performance. Furthermore, it has a function of increasing muscle mass, feather development and improving egg production in poultry.

 

Molar mass: 149.21 g/mol

Formula: C5H11NO2S

IUPAC ID: 2-amino-4-(methylthio)butanoic acid

Acidity (pKa): 2.28 (carboxyl), 9.21 (amino)

Structure and properties: Refractive index (n), Dielectric constant (εr), etc

Soluble in: Water

Lysine

Lysine is one of the most vital amino acids required in poultry nutrition. The main role of lysine is to participate in protein synthesis. Lysine is required for growth and maintenance, and it is considered a reference amino acid in the ideal protein diets

lysine

 

Molar mass: 146.19 g/mol

 

Formula: C6H14N2O2

IUPAC ID: Lysine

 

Soluble in: Water

Structure and properties: Refractive index (n), Dielectric constant (εr), etc

Threonine

Threonine helps keep connective tissues and muscles throughout the body strong and elastic, including the heart, where it is found in significant amounts. It also helps build strong bones, and may speed wound healing or recovery from injury.

threonin

Formula: C4H9NO3

Molar mass: 119.1192 g/mol

Acidity (pKa): 2.63 (carboxyl), 10.43 (amino)

Structure and properties: Refractive index (n), Dielectric constant (εr), etc

Solubility in water: (H2O, g/dl) 10.6(30°), 14.1(52°), 19.0(61°)

Valine

Valine is an essential and limiting amino acid in diets for poultry and swine. In typical diets for pigs, valine becomes the fifth limiting amino acid after lysine, threonine, methionine and tryptophan, It promotes muscle growth and tissue repair. It is a precursor in the penicillin biosynthetic pathway. Valine is one of three branched-chain amino acids (the others are leucine and isoleucine) that enhance energy, increase endurance, and aid in muscle tissue recovery and repair.

 

Formula: C5H11NO2

Molar mass: 117.151 g/mol

Melting point: 298 °C

Acidity (pKa): 2.32 (carboxyl), 9.62 (amino)

Structure and properties: Refractive index (n), Dielectric constant (εr), etc

Soluble in: Water

Tryptophan

In poultry, tryptophan increases feed intake, feed efficiency and serves as a precursor to niacin. … Based on these enormous roles of trp., it can be employed for use as a dietary supplement, antidepressant, higher feed intake, higher growth rate and feed efficiency, and as a niacin precursor
Molar mass: 204.23 g/mol

Formula: C11H12N2O2

IUPAC ID: Tryptophan or (2S)-2-amino-3-(1H-indol-3-yl)propanoic acid

Acidity (pKa): 2.38 (carboxyl), 9.39 (amino)

Structure and properties: Refractive index (n), Dielectric constant (εr), etc Soluble in: Water

tryptophan
