The formation from simpler components of ceramides, any N-acylated sphingoid.

The chemical reactions involving alditols, any polyhydric alcohol derived from the acyclic form of a monosaccharide by reduction of its aldehyde or keto group to an alcoholic group.

The formation from simpler components of peptides, compounds of 2 or more (but usually less than 100) amino acids where the alpha carboxyl group of one is bound to the alpha amino group of another.

The breakdown into simpler components of ceramides, any N-acetylated sphingoid.

Dynamic structural changes to eukaryotic chromatin that require energy from the hydrolysis of ATP, ranging from local changes necessary for transcriptional regulation to global changes necessary for chromosome segregation, mediated by ATP-dependent chromatin-remodelling factors.

The formation from simpler components of hypusine, N6-(4-amino-2-hydroxybutyl)-L-lysine.

DNA methylation during embryonic development

The covalent transfer of a methyl group to C-5 of cytosine during embryogenesis, when DNA methylation patterns are established.

The chemical reactions involving hypusine, N6-(4-amino-2-hydroxybutyl)-L-lysine.

The covalent transfer of a methyl group to C-5 of cytosine during gamete generation, when DNA methylation patterns are established.

The chemical reactions involving sphingoids, any of a class of compounds comprising sphinganine and its homologues and stereoisomers, and derivatives of these compounds.

The initial developmental process that will lead to the formation of the vertebrate inner ear. The otic placode forms as a thickening of the head ectoderm adjacent to the developing hindbrain.

The formation from simpler components of dolichols, any 2,3-dihydropolyprenol derived from four or more linked isoprene units.

age-dependent response to reactive oxygen species during chronological cell aging

age-dependent response to reactive oxygen species during chronological cell ageing

A change in state or activity of a cell or an organism occurring in non-dividing cells as they age as a result of reactive oxygen species, where the change varies according to the age of the cell or organism.
