The chemical reactions involving polyamines, any organic compound containing two or more amino groups.

Determination of the identity of part of an organism or organ where those parts are of the type that occur in the ventral region. Identity is considered to be the aggregate of characteristics by which a structure is recognized.

The formation from simpler components of polyamines, any organic compound containing two or more amino groups.

A change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a pain stimulus. Pain stimuli cause activation of nociceptors, peripheral receptors for pain, include receptors which are sensitive to painful mechanical stimuli, extreme heat or cold, and chemical stimuli.

The formation from simpler components of spermine, a polybasic amine found in human sperm, in ribosomes and in some viruses and involved in nucleic acid packaging.

A change in the behavior of an organism as a result of a pain stimulus. Pain stimuli cause activation of nociceptors, peripheral receptors for pain, include receptors which are sensitive to painful mechanical stimuli, extreme heat or cold, and chemical stimuli.

The breakdown into simpler components of polyamines, any organic compound containing two or more amino groups.

The chemical reactions involving phosphagen, any of a group of guanidine phosphates that occur in muscle and can be used to regenerate ATP from ADP during muscular contraction.

Assembly of clathrin triskelia into clathrin cage.

The directed movement of iron ions into, out of or within a mitochondrion.

Assembly of the extracellular matrix fibers that enables the matrix to recoil after transient stretching.

The chemical reactions involving lauric acid, a fatty acid with the formula CH3(CH2)10COOH. Derived from vegetable sources.

Prevention of degradation of mRNA molecules. In the absence of compensating changes in other processes, the slowing of mRNA degradation can result in an overall increase in the population of active mRNA molecules.
