The chemical reactions involving amino acids of the histidine family.

The sequential, electrochemical polarization and depolarisation that travels across the membrane of a nerve cell (neuron) in response to stimulation.

histidine family amino acid biosynthesis

The formation from simpler components of amino acids of the histidine family.

The breakdown into simpler components of amino acids of the histidine family.

positive regulation of T cell activation

positive regulation of B-lymphocyte activation

Any process that activates or increases the rate of T cell activation.

The chemical reactions involving tetraterpenoid compounds, terpenoids with 40 isoprenoid units.

positive regulation of B cell activation

Any process that activates or increases the rate of B cell activation.

Any process that modulates the frequency, rate or extent of reductions in the diameter of blood vessels.

The formation from simpler components of tetraterpenoid compounds, terpenoids with 40 isoprenoid units.

The process whereby a relatively unspecialized cell acquires specialized features of a white adipocyte, an animal connective tissue cell involved in energy storage. White adipocytes have cytoplasmic lipids arranged in a unique vacuole.

Catalysis of the reaction: heme + 3 donor-H2 + 3 O2 = biliverdin + Fe2+ + CO + 3 acceptor + 3 H2O.

The process whereby a relatively unspecialized cell acquires specialized features of a brown adipocyte, an animal connective tissue cell involved in adaptive thermogenesis. Brown adipocytes contain multiple small droplets of triglycerides and a high number of mitochondria.

The processes pertinent to the function of an organism above the cellular level; includes the integrated processes of tissues and organs.

Catalysis of the reaction: S-adenosyl-L-methionine + 3-hexaprenyl-4,5-dihydroxybenzoate = S-adenosyl-L-homocysteine + 3-hexaprenyl-4-hydroxy-5-methoxybenzoate.

The processes pertinent to the reproductive function of an organism.

Catalysis of the reaction: ATP + D-hexose = ADP + D-hexose 6-phosphate.
