10995359-7	2000	For the development of biodegradable materials with good mechanical properties from these biopolymers, disulfide bonds between the keratin molecules are needed.	Disulfides	103-112	keratin	Gallus gallus	131-138	
28801097-5	2018	Moreover, the films processed by compression moulding showed enhanced tensile strength, which increased with the incorporation of hydrolyzed keratin due to the formation of disulfide bonds.	Disulfides	173-182	keratin	Gallus gallus	141-148	
13970458-11	1963	It is suggested that lipids serve as a framework for the developing keratin structure which acquires permanent stability through hydrogen bonds and disulfide cross-links.	Disulfides	148-157	keratin	Gallus gallus	68-75	
28601997-6	2017	Analysis of amino acid composition showed a severe damage to the disulfide bonds in keratin during the extraction procedure.	Disulfides	65-74	keratin	Gallus gallus	84-91
