Vitamin B12, also known as cobalamin, is a water-soluble vitamin involved in metabolism. It is one of eight B vitamins. It is required by animals, which use it as a cofactor in DNA synthesis, and in both fatty acid and amino acid metabolism. It is important in the normal functioning of the nervous system via its role in the synthesis of myelin, and in the circulatory system in the maturation of red blood cells in the bone marrow. Plants do not need cobalamin and carry out the reactions with enzymes that are not dependent on it.
Molecular Model of Cytochrome P450, CYP2D6, a major protein for drug metabolism
Collagen protein molecule. Molecular model. 3D rendering. Illustration
Background created by fractal geometry.
Interleukin 13 (IL-13) cytokine protein. 3D illustration. Cartoon representation combined with semi-transparent surfaces.
A ball and stick + ribbons model of Bowman-Birk Protease Inhibitor, more commonly abbreviated to BBI. It is used clinically to treat and help prevent cancer.
The glucagon like peptide-1 receptor (GLPr) is a G proteincoupled receptor (GPCR) that mediates the action of GLP-1, a peptide hormone. The activated receptor  has a strong effect  on the management of type 2 diabetes mellitus and obesity, including glucose homeostasis and regulation of gastric motility and food intake.
Human had writing word endorphins and chemical formula. Endorphins are among the brain chemicals known as neurotransmitters, which function to transmit electrical signals within the nervous system
Basal-cell carcinoma (BCC), also known as basal-cell cancer, is the most common type of skin cancer. It often appears as a painless raised area of skin, which may be shiny with small blood vessels running over it. It may also present as a raised area with ulceration. Basal-cell cancer grows slowly and can damage the tissue around it, but it is unlikely to spread to distant areas or result in death.
Molecular Model of Cyclosporine, an immunosuppressant drug widely used in organ transplantation to prevent rejection.
