The GLUT1 protein that transports glucose across the blood brain barrier is encoded by the SLC2A1 gene, located on chromosome 1. [8] In GLUT1 deficiency syndrome, one of the two genes is damaged by a mutation and an insufficient amount protein is made. As a result, insufficient glucose is passing the blood brain barrier.
Even diets of mild protein undernutrition (7.2%) have been shown to have lasting and significant effects in rats. The following are some studies in which prenatal protein deficiency has been shown to have unfavorable consequences. Decreased brain size: Protein deficiency has been shown to affect the size and composition of brains in rhesus monkeys.
Reelin's name comes from the abnormal reeling gait of reeler mice, [17] which were later found to have a deficiency of this brain protein and were homozygous for mutation of the RELN gene. The primary phenotype associated with loss of reelin function is a failure of neuronal positioning throughout the developing central nervous system (CNS).
Studies have shown that a protein intake of 1.2 to 2.0 grams of protein per kilogram of body weight is best for adults over 65—a far cry from the 0.8 grams per kilogram that is outlined in the ...
Poor diet in early childhood affects the number of neurons in parts of the brain. [1]Nutritional neuroscience is the scientific discipline that studies the effects various components of the diet such as minerals, vitamins, protein, carbohydrates, fats, dietary supplements, synthetic hormones, and food additives have on neurochemistry, neurobiology, behavior, and cognition.
Orexin (/ ɒ ˈ r ɛ k s ɪ n /), also known as hypocretin, is a neuropeptide that regulates arousal, wakefulness, and appetite. [5] It exists in the forms of orexin-A and orexin-B.The most common form of narcolepsy, type 1, in which the individual experiences brief losses of muscle tone ("drop attacks" or cataplexy), is caused by a lack of orexin in the brain due to destruction of the cells ...
Memory is commonly referred to as the ability to encode, store, retain and subsequently recall information and past experiences in the human brain. This process involves many proteins, one of which is the Histone-binding protein RbAp48 (also known as RBBP4 or NURF55), encoded by the RBBP4 gene in humans. [1] Structure of protein RBBP4
An "exchange" system can be used to calculate the amount of Phe in a portion of food from the protein content identified on a nutritional information label. Lower-protein "medical food" substitutes are often used in place of normal bread, pasta, and other grain-based foods, which contain a significant amount of Phe. Many fruits and vegetables ...
