SIRT4 is a mitochondrial ADP-ribosyltransferase that inhibits mitochondrial glutamate dehydrogenase 1 activity, thereby downregulating insulin secretion in response to amino acids. [7] A deacetylation of malonyl-CoA decarboxylase enzyme by SIRT4 represses the enzyme activity, inhibiting fatty acid oxidation in muscle and liver cells.
To ensure good health, it is important to provide dogs with the 22 amino acids which they require. Of these 22 amino acids, 12 can be synthesized. The rest must be provided by good sources of dietary protein in adequate quantities. Good sources of protein include eggs and fish, which have a high biological value. This value describes the ...
A study performed in 2015 with vervet monkeys (Chlorocebus sabaeus) in St. Kitts, which are homozygous for the apoE4 gene (a condition which in humans is a risk factor for Alzheimer's disease), found that vervets that were administered BMAA orally developed hallmark histopathology features of Alzheimer's disease, including amyloid beta plaques and neurofibrillary tangle accumulation.
Many diets targeted for performance dogs contain 30% protein. However, dogs performing in different athletic activities can require varying amounts of protein and essential amino acids. For instance, studies have shown that sled dogs require a high protein, high fat diet, where 30 to 40% of energy comes from protein and 50% of energy comes from ...
The Van Slyke determination is a chemical test for the determination of amino acids containing a primary amine group. It is named after the biochemist Donald Dexter Van Slyke (1883-1971). [1] One of Van Slyke's first professional achievements was the quantification of amino acids by the Van Slyke determination reaction. [2]
The DLA DQA1 alleles code for an arginine amino acid at position 55 in region two, this increases the risk of developing diabetes in dog as arginine is a positive amino acid which can impair antigen binding. This allele is also associated with hypothyroidism which implies that this allele increases susceptibility for endocrinopathic immune ...
Protein toxicity is the effect of the buildup of protein metabolic waste compounds, like urea, uric acid, ammonia, and creatinine.Protein toxicity has many causes, including urea cycle disorders, genetic mutations, excessive protein intake, and insufficient kidney function, such as chronic kidney disease and acute kidney injury.
Amino acid biosynthesis is the set of biochemical processes (metabolic pathways) by which the amino acids are produced. The substrates for these processes are various compounds in the organism's diet or growth media. Not all organisms are able to synthesize all amino acids. For example, humans can synthesize 11 of the 20 standard amino acids ...
