Institute of Molecular Genetics, Russian Academy of Sciences, Moscow.

The study of age changes of amidolytic activity of Vipera berus venom is investigated using mixtures of chromogenic peptide substrates differing by detected groups. Quantities of venom (total protein content) and its proteolytic activity from snakes of different ages were compared. The venom composition of newly born adders was shown to be considerably different from the venom composition of young (12-month) adders of the same population. The next evolution of protease activity is weakly expressed.

D000577	Amides	Organic compounds containing the -CO-NH2 radical. Amides are derived from acids by replacement of -OH by -NH2 or from ammonia by the replacement of H by an acyl group. (From Grant & Hackh's Chemical Dictionary, 5th ed)	Amide
D000595	Amino Acid Sequence	The order of amino acids as they occur in a polypeptide chain. This is referred to as the primary structure of proteins. It is of fundamental importance in determining PROTEIN CONFORMATION.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D012911	Snakes	Limbless REPTILES of the suborder Serpentes.	Serpentes,Ophidia,Snake
D014757	Viper Venoms	Venoms from SNAKES of the viperid family. They tend to be less toxic than elapid or hydrophid venoms and act mainly on the vascular system, interfering with coagulation and capillary membrane integrity and are highly cytotoxic. They contain large amounts of several enzymes, other factors, and some toxins.
