Biochemistry of brain

Human brain biochemistry

The human brain that serves as a center of the nervous system is structurally unique. It is extraordinarily complex and highly specialized in its distinct heterogeneous anatomical regions as its function remains a great challenge. The neuron is the functional unit that depends on special anatomical and chemical connections with other units of the system. The essential biochemical connections of...

Biochemistry of the filaments of brain.

Intermediate filaments-cytoplasmic filaments with a diameter of 8-9 nm-have been described in a large variety of cell types. In this study, the subunit protein of the neurofilament and the presumptive subunit of the astroglial filament are compared by immunological and biochemical methods and are found to be very similar. Strong crossreactions are also found between these proteins in a variety ...

New Data on the Functional Biochemistry of the Brain

Polyamine metabolism in brain tumours: diagnostic relevance of quantitative biochemistry.

OBJECTIVE Activation of polyamine metabolism is closely associated with cellular proliferation. The purpose was to investigate whether the content of the polyamines putrescine, spermidine, and spermine, and the activity of the first metabolic key enzyme of polyamine metabolism, ornithine decarboxylase (ODC), represent biochemical markers of malignancy in brain tumours. METHODS The concentrati...

Biochemistry of human skin--our brain on the outside.

The skin, our body's largest organ, is located at the interface between the external and internal environments, and so is strategically placed to provide not only a barrier against a range of noxious stressors (UV radiation, mechanical, chemical and biological insults) but also to act as the periphery's 'sensing' system. Recent developments suggest that this organ is much more critical to maint...
