The paper presents the synthesis of acylated and esterified derivatives of
collagen hydrolyzates. Also, the influence of average molecular weight, typ
e of reactive, pH, temperature and reactant concentration on the properties
of the resulting products are discussed. Blocking of the basic function ha
s been made in aqueous medium with acid chlorides and anhydrides. A non-aqu
eous method has been used for esterification with aliphatic alcohols.
