Names of Acid Chlorides in General Acid chlorides are also known generically as acyl chlorides link to equivalent page about naming acyl chlorides. Acid chlorides are named according to the same system as other organic compounds. In the simplest case of linear acid chlorides, the suffix -oyl chloride is added to the stem used to indicate the number of carbon atoms in the longest chain within the molecule. That is, when naming acid chlorides the first step is to consider the number of carbon atoms forming the longest chain within the molecule.
It is an isomer of isophthalic acid and terephthalic acid.

Folate is also needed to produce healthy red blood cells and is critical during periods of rapid growth, such as during pregnancy and fetal development. Men and women ages 19 years and older should aim for 400 mcg DFE. People who regularly drink alcohol should aim for at least 600 mcg DFE of folate daily since alcohol can impair its absorption. The UL for adults for folic acid from fortified food or supplements not including folate from food is set at 1,000 mcg a day. Folate and Health Neural tube defects One of the advances that changed the way we look at vitamins was the discovery that too little folate is linked to birth defects of the spine spina bifida and brain anencephaly. Fifty years ago, no one knew what caused these birth defects, which occur when the early development of tissues that eventually become the spinal cord, the tissues surrounding it, or the brain goes awry. More than 30 years ago, British researchers found that mothers of children with spina bifida had low vitamin levels. For folate to be effective, it must be taken in the first few weeks after conception, often before a woman knows she is pregnant. That is why women of childbearing age are urged to take extra folic acid as a supplement.
Food and Drug Administration now requires that folic acid be added to most enriched breads, flour, cornmeal, pastas, rice, and other grain products, along with the iron and other micronutrients that have been added for years. Both had inherited conditions that caused them to have extremely high levels of a protein breakdown product in their blood, and both had arteries as clogged with cholesterol as those of a 65-year-old fast food addict. How do B vitamins fit into the homocysteine picture? Folate and vitamin B12 play key roles in converting homocysteine into methionine, one of the 20 or so building blocks from which the body builds new proteins.

Перевод "кислота" на английский язык:
Ultimately, folic acid supplementation may only reduce the risk of heart disease in people who have lower levels of folate intake, most likely in countries that do not fortify their food supply with folic acid. In people who already get enough folate in their diets, further supplementation with high doses of folic acid supplements—much higher than what is found in a standard multivitamin—has not been found to be beneficial and might actually cause harm. A Cochrane review of 15 randomized controlled trials found that folic acid supplements, taken alone or with other B vitamins, compared with a placebo did not show a significant difference on rates of heart attack and cardiovascular disease deaths but it did reduce the risk of stroke. There was no significant effect on heart disease alone. However, the greatest benefit was seen for people with lower blood levels of folate and without a history of cardiovascular diseases. The supplements also appeared to most benefit those whose homocysteine levels had the greatest drop. It is believed that folate may play a role in both suppressing some types of early cancer, as well as progressing established cancers if high doses of folic acid are used. Observational studies show that people who get higher than average amounts of folate from their diets or folic acid supplements for 15 years or more have lower risks of colon cancer [25] and breast cancer. A multiyear trial looked at whether high-dose folic acid supplements could prevent new polyps in people who had a history of polyps. Keep in mind that this study tested a high dose of folic acid, more than two times higher than what is found in a standard multivitamin; furthermore, study participants were already at a very high risk of developing new polyps. This may be another case where timing of folate intake is critical.
Getting adequate folate may prevent polyps in people who do not have them, but high dose folic acid supplements may speed up polyp growth in people who do. The steady decline in deaths from colon cancer before and after the onset of folic acid fortification suggests that screening, not folic acid fortification, is responsible for the uptick in colon cancer rates.

Certain acids are used as drugs. Acetylsalicylic acid Aspirin is used as a pain killer and for bringing down fevers. Acids play very important roles in the human body. The hydrochloric acid present in our stomach aids in digestion by breaking down large and complex food molecules. Amino acids are required for synthesis of proteins required for growth and repair of our body tissues. Fatty acids are also required for growth and repair of body tissues. Nucleic acids are important for the manufacturing of DNA, RNA and transmission of characters to offspring through genes.
Carbonic acid is important for maintenance of pH equilibrium in the body. Acid catalysis Main article: Acid catalysis Acids are used as catalysts in industrial and organic chemistry; for example, sulfuric acid is used in very large quantities in the alkylation process to produce gasoline. Strong acids, such as sulfuric, phosphoric and hydrochloric acids also effect dehydration and condensation reactions. In biochemistry, many enzymes employ acid catalysis. Many biologically important molecules are acids. DNA contains the chemical blueprint for the synthesis of proteins which are made up of amino acid subunits.
Cell membranes contain fatty acid esters such as phospholipids. The variable group, also called the R group or side chain, determines the identity and many of the properties of a specific amino acid. In glycine , the simplest amino acid, the R group is a hydrogen atom, but in all other amino acids it is contains one or more carbon atoms bonded to hydrogens, and may contain other elements such as sulfur, oxygen or nitrogen. With the exception of glycine, naturally occurring amino acids are chiral and almost invariably occur in the -configuration.
