Plankton, the chief food source of fish, was assessed as the possible dietary origin of vitamin D in fish. The presence of vitamin D compounds were examined in fresh water phytoplankton and zooplankton employing a series of chromatographic procedures. Abundant amounts of provitamins D and vitamins D (D2 and D3) were found in the fresh water plankton. The high amount of vitamin D observed may be due to exposure of plankton to sunlight because the plankton were caught during the summer month. Thus, plankton may be an important contributor to vitamin D in fish.
In biochemistry, eicosanoids are signaling molecules derived from omega-3 (ω-3) or omega-6 (ω-6) fats. They exert complex control over many bodily systems, especially in inflammation, immunity and as messengers in the central nervous system. The network
Julie Matthews has devoted her life to finding ways to heal the devastating symptoms of autism.She's an autism nutrition specialist and a Defeat Autism Now!(DAN) practitioner who has written a must-read book for parents and caregivers or anyone who deals with autism.The book,Nourishing Hope for Autism: Nutrition Intervention for Healing Our Children,deals with the diet and nutrition aspect of successfully treating autism.Matthews'fascination with biochemistry and the mechanisms of the body led her to discover that most adults and children with ASD (autistic spectrum disorders) have imbalances in their body's chemistry.
In chemistry, especially biochemistry, a fatty acid is a carboxylic acid often with a long unbranched aliphatic tail (chain), which is either saturated or unsaturated. Carboxylic acids as short as butyric acid (4 carbon atoms) are considered to be fatty a
In chemistry, an amino acid is a molecule that contains both amine and carboxyl functional groups. In biochemistry, this term refers to alpha-amino acids with the general formula H2NCHRCOOH, where R is an organic substituent.[1] In the alpha amino acids,
"The omega-3 essential fatty acids commonly found in fatty fish and algae help animals avoid sensory overload, according to research published by the American Psychological Association. The finding connects low omega-3s to the information-processing problems found in people with schizophrenia; bipolar, obsessive-compulsive, and attention-deficit hyperactivity disorders; Huntington's disease; and other afflictions of the nervous system.
The study, reported in the journal Behavioral Neuroscience, provides more evidence that fish is brain food. The key finding was that two omega-3 fatty acids docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) appear to be most useful in the nervous system, maybe by maintaining nerve-cell membranes.
"It is an uphill battle now to reverse the message that 'fats are bad,' and to increase omega-3 fats in our diet," said Norman Salem Jr., PhD, who led this study at the Laboratory of Membrane Biochemistry and Biophysics at the National Institute on Alcohol Abuse and Alcoholism.
"ScienceDaily (Nov. 30, 2009) - Universitat Autònoma de Barcelona (UAB) researchers have confirmed that a diet rich in polyphenols and polyunsaturated fatty acids, patented as an LMN diet, helps boost the production of the brain's stem cells -neurogenesis- and strengthens their differentiation in different types of neuron cells.
The research revealed that mice fed an LMN diet, when compared to those fed a control diet, have more cell proliferation in the two areas of the brain where neurogenesis is produced, the olfactory bulb and the hippocampus, both of which are greatly damaged in patients with Alzheimer's disease. These results give support to the hypothesis that a diet made up of foods rich in these antioxidant substances could delay the onset of this disease or even slow down its evolution.
The study will be published in the December issue of the Journal of Alzheimer's Disease and was directed by Mercedes Unzeta, professor of the UAB Department of Biochemistry and Molecular Biology"
"(NaturalNews) People still don't get it: Vitamin D is the "miracle nutrient" that activates your immune system to defend you against invading microorganisms -- including seasonal flu and swine flu. Two months ago, an important study was published by researchers at Oregon State University. This study reveals something startling: Vitamin D is so crucial to the functioning of your immune system that the ability of vitamin D to boost immune function and destroy invading microorganisms has been conserved in the genome for over 60 million years of evolution.
As this press release from Oregon State University (http://www.eurekalert.org/pub_relea...) explains:
The fact that this vitamin-D mediated immune response has been retained through millions of years of evolutionary selection, and is still found in species ranging from squirrel monkeys to baboons and humans, suggests that it must be critical to their survival, researchers say.
"The existence and importance of this part of our immune response makes it clear that humans and other primates need to maintain sufficient levels of vitamin D," said Adrian Gombart, an associate professor of biochemistry and a principal investigator with the Linus Pauling Institute at Oregon State University."

Colin Campbell, Professor of Nutritional Biochemistry at Cornell University, author of The China Study and Dr. Loren Cordain Professor, Department of Health & Exercise Science, Colorado State University, author of The Paleo Diet-make their competing cases for the role of dietary protein in health and disease.

Carbohydrates are most important source of energy for metabolism. It is known as saccharine in Biochemistry and is divided into four chemical components such as Mono, Di, Oligo and Polysaccharides. While the former both are known as simple sugars and the latter both are called complex sugars.
Why "Vitamin D" is not a hormone, and not a synonym for 1,25-dihydroxy-vitamin D, its analogs or deltanoids.
