The chemical reactions involving apocarotenoids, a class of compounds derived from the oxidative cleavage of carotenoids, many of which are biologically important e.g. retinal and abscisic acid.

Catalysis of the reaction: thiamin triphosphate + H2O = thiamin diphosphate + phosphate.

Catalysis of the reaction: N-Acetyl-L-Asp-L-Glu + H2O = N-Acetyl-L-Asp + L-Glu.

Any process that modulates the frequency, rate or extent of absorption of cholesterol into the blood, and the exclusion of other sterols from absorption.

The directed movement of cholesterol, cholest-5-en-3-beta-ol, into, out of, within or between cells.

inner kinetochore of condensed chromosome

The region of a condensed chromosome kinetochore closest to centromeric DNA; in mammals the CREST antigens (CENP proteins) are found in this layer; this layer may help define underlying centromeric chromatin structure and position of the kinetochore on the chromosome.

Catalysis of the cleavage of peptide bonds in collagen with preferential cleavage where P1', P2' and P3' are hydrophobic residues; action on collagen types III, IV and V is weak.

Stops, prevents or reduces the activity of the serine endopeptidase trypsin.

Catalysis of the cleavage of heparan sulfate; can degrade both heparan sulfate and heparin glycosaminoglycan chains.

Interacting selectively with ARF, ADP-ribosylation factor, a small monomeric cytosolic GTPase that, when bound to GTP, binds to the membranes of cells.

Any process that stops, prevents or reduces the rate of cell growth.

Organized structure of distinctive morphology and function, not bounded by a lipid bilayer membrane. Includes ribosomes, the cytoskeleton and chromosomes.

The formation from simpler components of interferon type I.

The process by which the identity of an organ primordium is specified. Identity is considered to be the aggregate of characteristics by which a structure is recognized.

Any process that modulates the mass, volume, or shape of a cell.

The change in form (cell shape and size) that occurs when relatively unspecialized cells, e.g. embryonic or regenerative cells, acquire specialized structural and/or functional features that characterize the cells, tissues, or organs of the mature organism or some other relatively stable phase of the organism's life history.
