Standard phenylalanine concentrations in unaffected persons are about 2-6mg/dl (120–360 μmol/L) phenylalanine concentrations in those with untreated hyperphenylalaninemia can be up to 20 mg/dL (1200 μmol/L). Measurable IQ deficits are often detected as phenylalanine levels approach 10 mg/dL (600 mol/L).
[6] [7] [8] [1] [9] In mice, high levels of Lac-Phe in the blood cause a decrease of food intake [6] and in humans, its production has been shown to correlate with adipose tissue loss during an endurance exercise intervention. [10] In mammals it is created from -lactate and L-phenylalanine by the cytosol nonspecific dipeptidase (CNDP2) protein. [1]
The basic cause of sporadic (non-familial) cancers is DNA damage and genomic instability. [1] [2] A minority of cancers are due to inherited genetic mutations. [3] Most cancers are related to environmental, lifestyle, or behavioral exposures. [4] Cancer is generally not contagious in humans, though it can be caused by oncoviruses and cancer ...
Phenylalanine (symbol Phe or F) [3] is an essential α-amino acid with the formula C 9 H 11 NO 2. It can be viewed as a benzyl group substituted for the methyl group of alanine, or a phenyl group in place of a terminal hydrogen of alanine.
Phenylalanine is a large, neutral amino acid (LNAA). LNAAs compete for transport across the blood–brain barrier (BBB) via the large neutral amino acid transporter (LNAAT). If phenylalanine is in excess in the blood, it will saturate the transporter. Excessive levels of phenylalanine tend to decrease the levels of other LNAAs in the brain.
The IARC panel said on Friday it had made its ruling based on three studies in humans in the United States and Europe that indicated a link between hepatocellular carcinoma, a form of liver cancer ...
The chemical, which is the active ingredient in the weed killer Roundup, can allegedly cause cancer. The oat products tested were made by General Mills, including several Cheerios varieties and ...
The "radiofrequency electromagnetic fields" associated with using mobile phones are "possibly cancer-causing". Like aspartame, this means there is either limited evidence they can cause cancer in ...
