Lysine low ph
Lysine production for animal feed is a major global industry, reaching in 2009 almost 700,000 tons for a market value of over €1.22 billion. Lysine is an important additive to animal feed because it is a limiting amino acid when optimizing the growth of certain animals such as pigs and chickens for the production of meat. Lysine supplementation allows for the use of lower-cost plant protein (maize, for instance, rather than soy) while maintaining high growth rates, and limiting the polluti… Web22 feb. 2013 · At low pH values PLL mainly possesses the PII and β structures while at higher pH values and low temperatures characteristic bands for the α-helical conformation are found.
