Arachidonic acid is an omega-6 fatty acid that is present in the phospholipids (especially phosphatidylethanolamine, phosphatidylcholine and phosphatidylinositides) of membranes of the body's cells, and is abundant in the brain. It is the counterpart to the saturated arachidic acid found in peanut oil.
Fat molecules serve as energy storage for fat cells. They consist of three fatty acids attached to a backbone of glycerol.
Researchers at the University of Michigan Rogel Cancer Center found that a cytokine, a category of protein that acts as messengers in the body, and a fatty acid can work together to trigger a type of cell death previously defined by studies with synthetic molecules.
Like people, cells in the human body protect their personal space. They seem to know how much space they need, and if it gets too tight, most cells prefer to break free.
Camelina sativa oil and fatty fish are rich in polyunsaturated omega-3 fatty acids, but their health benefits seem to differ.
A team of Australian researchers has confirmed the feasibility and potential of applying integrated lipidomics and proteomics to malignant plasma cells from myeloma patients.
