CompoundDescription
Carbon DioxideA colorless, odorless gas that can be formed by the body and is necessary for the respiration cycle of plants and animals.
ornithineAn amino acid produced in the urea cycle by the splitting off of urea from arginine.
spermidineA polyamine formed from putrescine. It is found in almost all tissues in association with nucleic acids. It is found as a cation at all pH values, and is thought to help stabilize some membranes and nucleic acid structures. It is a precursor of spermine.
spermineA biogenic polyamine formed from spermidine. It is found in a wide variety of organisms and tissues and is an essential growth factor in some bacteria. It is found as a polycation at all pH values. Spermine is associated with nucleic acids, particularly in viruses, and is thought to stabilize the helical structure.
5'-methylthioadenosinestructure
s-adenosyl-3-methylthiopropylaminedecarboxylated S-adenosylmethionine
putrescineA toxic diamine formed by putrefaction from the decarboxylation of arginine and ornithine.
