Methionine

In the 1960s when a gene was first isolated from E. coli, the consensus was that proteins were produced from the DNA sequence and this was also the source of regulation. A change in the DNA sequence changed the protein product. Now we realize that there are exceptions. Epigenetic refers to the external modification that turns genes “on” or “off” to DNA. These modifications in DNA sequence don’t change, but can affect the “read” of genes [1]. One example is epigenetics in lung cancer. It is…

sitosterol (Benvineste, 2002). The role of lanosterol in plants is unclear. An increase in sterol sidechain length occurs by two alkylation reactions. Cycloartenol is methylated by the enzyme sterol methyltransferase type-1 (SMT1) at C-24. S-adenosyl methionine acts as the methyl donor in this process, thus introducing one nonacetyl-CoA carbon atom in the plant sterol structure. Transgenic potato plants overexpressing a SMT1 cDNA displayed an increase in total sterols, especially in…

and 1.5% pectin, organic acids (citric, malic, tartaric, succinic, fumaric, ascorbic acid), fatty acids (conjugated linoleic acid, linoleic acid, punicic acid and eleostearic acid), amino acids (proline, valin, glutamic acid, aspartic acid and methionine) and polyphenols. The soluble…

Humans are easily affected by events in their in life in which can cause them to feel sadness or happiness. These experiences of daily fluctuations are common and happen to everyone. In some people, however, these fluctuations become excessive in terms of intensity and duration, and then it starts to interfere significantly with their daily lives. In these cases, we are facing a mental depression frame. Depression is a serious mental disorder and it is the most prevalent mental disorder in the…

Ricketts is a condition that affects bone development, usually reported in children, bringing about bone deformities. Lack of Vitamin D, phosphorus or calcium are the most common causes of this condition. Symptoms can include; skeletal pain, skeletal deformities such as “bowed legs” or curvature of the spine. There is also a high chance of bone fracturing. Vitamin D is the most common cause and is essential for the absorption of calcium in the gut. The main source of Vitamin D comes from natural…

Living in a utopia where it is utter blasphemy to harm animals for human consumption should be an ideal to strive for. Most modern society is aware of this “ideal”, and there is even “research” that shows humans would be healthier if they become vegetarian. Yes, the consumption of meat was essential for the development of the human species, but have humans not mentally and emotionally evolved from those barbarous creatures they once were? But if being a vegetarian is the next big step for…

inside out exposing the base pairs, this is called ‘base flipping’, once the cytosine is exposed, a cysteine is used to nucleophilically attack the sixth carbon of the cytosine (C6), this transfers a methyl group from another molecule S-adenosyl-I-methionine, to the fifth carbon on the cytosine (C5), this creates 5-methyl cytosine (Zhang and Bruice,…

control appetite, reduces anxiety, increases metabolism and prevents loss of muscle mass. The recommended dose is about 400 mcg daily. 4. L-carnitine is a nutrient synthesized in the liver, kidneys and brain from two essential amino acids, lysine and methionine. It has been shown that helps burn fat and prevent muscle loss. The recommended dose is 500 mg / day. In conclusion, muscle weighs more than fat, and the more muscle you have, the greater will be your metabolism will burn more calories…

Busulfan is anticancer drug caused variety of adverse effects for cancer patients. It’s used to treatment of chronic leukaemia but it could cause damage to the male reproductive system as one of its adverse effects. This study aim to investigate the effect of L-carnitine and L-arginine on semen quality, oxidative stress parameters, caspase3 and testes cell energy after busulfan treatment. Materials and Methods: thirty-two adult male rats were divided into four groups. Group I (Control)…

Creutzfeldt-Jakob disease Creutzfeldt-Jakob Disease (CJD)= a universally fatal neurodegenerative disease • Swift: Kills 90% of patients within 1 year of prognosis • Rare: 1 case out of 1 million people worldwide Phenotypes= observable characteristics of an individual with CJD • Cognitive: Disorientation, memory loss, mental confusion, dementia o Ex. “I have trouble falling down” • Muscular: Slow body movement, jerking muscle spasms, coordination impairment o Ex. balance problems • Other:…
