Document Summary
*the more methyl groups, the more silenced a gene is. B vitamins play a prominent role in cellular respiration: act as coenzymes. Glutathione peroxidase (neutralizes peroxides) helps to spare vitamin e. Vitamin b12 helps maintain the myelin sheath. Vitamin b6 and amino acids are important for neurotransmitters. Vitamin c is important for strong, healthy, cross-linked connective tissue. Vitamin k synthesis of proteins that regulate bone metabolism: neurotransmitters are released from end of terminal into the synapse and then it binds to the next neuron this requires vitamin b6. Folate is important for neural tube close. Dha is important for the development of the brain and the eyes. Vitamin a deficiency results in xerophthalmia (if untreated it causes blindness) Macular degeneration lutien (concentrates in the retina of the eye) and zeaxanthin. Inflammation: omega-6 pro-inflammatory, omega 3 anti-inflammatory. Antioxidants: phagocytes produce free radicals to destroy pathogens (respiratory burst, need antioxidants to protect immune cells from free radicals.
