The l-aspartate amino acids (AFAAs) are constituted of l-aspartate, l-lysine, l-methionine, l-threonine and l-isoleucine. Except for l-aspartate, AFAAs are essential amino acids that cannot be synthesized by humans and most farm animals, and thus possess wide applications in food, animal feed, pharmaceutical and cosmetics industries. To date, a number of amino acids, including AFAAs have been industrially...
A series of novel sodium humate/poly(N-isopropylacrylamide) (SH/PNIPA) hydrogels were synthesized by solution polymerization. The swelling and decoloring properties of SH/PNIPA hydrogels were also examined. Experiment results show that there exist hydrogen-bonding interactions between SH and PNIPA in the SH/PNIPA hydrogels network, which are not strong enough to disrupt the aggregation of dehydrated...
