Phenolic acids are plant metabolites widely spread throughout the plant kingdom. Recent interest in phenolic acids stems from their potential protective role, through ingestion of fruits and vegetables, against oxidative damage diseases coronary heart disease, stroke, and cancers.

Phenolic compounds are essential for the growth and reproduction of plants, and are produced as a response for defending injured plants against pathogens.

The importance of antioxidant activities of phenolic compounds and their possible usage in processed foods as a natural antioxidant have reached a new high in recent years. Absorption The absorption and bioavailability of phenolics in humans carboxylic acid and cancer controversial. Data on these aspects of phenolics are scarce and merely highlight the need for extensive investigations of the handling of phenolics by the gastrointestinal tract and their subsequent absorption and metabolism.

Rocz Panstw Zakl Hig. Digestion and absorption of phenolic compounds assessed by in vitro simulation methods. Phenolic compounds are a group of key plant metabolites found abundantly in fruit and vegetables.

Because of their antioxidant properties, they play a significant role in preventing various degenerative illnesses, tumours or cardiovascular disease. In nature, they are present in foods mainly as esters, glycosides and polymers which need to undergo enzymatic hydrolysis in the digestive tract or by the gut microflora before becoming absorbed.

The biological properties of these phenolic compounds undergoing this degradation, are thus governed by their absorption alternative and complementary cancer therapies well as metabolism.

Many methods are used to assess the rates and the degrees to which these substances are digested and absorbed, both in vivo and in vitro ones, where the former are the most reliable, although they suffer from various limitations.

For this reason, many in vitro models have now arisen to simulate the function of human digestion in the attempt to faithfully re-create real-life conditions. Mechanisms of polyphenols absorption have been principally studied by intestinal epithelial cell models, in particular, those using the Caco-2 cell line. Phenolics in Plants Phenolic acid compounds seem to be carboxylic acid and cancer distributed in plants.

They have been the subject of a great number of chemical, biological, agricultural, carboxylic acid and cancer, and medical studies. They form a diverse group that includes the widely distributed hydroxybenzoic and hydroxycinnamic acids. Caffeic acid dominates in all of these samples except in tea brews. Cancer fighting properties Food Chem. Cytotoxic impact of phenolics from Lamiaceae species on human breast cancer cells. The aim of this study was to evaluate the cytotoxicity of dried aqueous extracts from Thymus serpyllum ExTsThymus vulgaris, Majorana hortensis ExMhand Mentha piperita, and the phenolic compounds caffeic acid CArosmarinic acid RAlithospermic acid LA carboxylic acid and cancer, luteolinO-glucuronide LgrluteolinO-rutinoside LreriodictiolO-rutinoside Erand arbutin Abon two human breast cancer cell lines: It might be concluded that the tested phenolics exhibited more beneficial properties when they were applied in the form of extracts comprising their mixtures, carboxylic acid and cancer.

These may be beneficial in the prevention of colon cancer and familial adenomatous polyposis. Phenolic acids and cholesterol Drinking a cup of coffee induces an increase in the resistance of LDL cholesterol to oxidative changes, probably as a result of the incorporation of phenolic acids found in coffee into LDL cholesterol.

Chemistry Plant phenolic compounds are diverse in structure but are characterised by hydroxylated aromatic rings e.

They are categorised as secondary metabolites, and their function in plants is often poorly understood. Many plant phenolic compounds are polymerised into larger molecules such as the proanthocyanidins PA; condensed tannins and lignins. Furthermore, phenolic acids may occur carboxylic acid and cancer food plants as esters or glycosides conjugated with other natural compounds such as flavonoids, alcohols, hydroxyfatty acids, carboxylic acid and cancer, sterols, and glucosides.

Phenols Phenols, sometimes called phenolics, are a class of chemical compounds consisting of a hydroxyl functional group -OH attached to an aromatic hydrocarbon group. The simplest of the class is phenol C6H5OH. Some phenols are germicidal and are used in formulating disinfectants. Others possess estrogenic or endocrine disrupting activity. Phenolic compounds Phenol, the parent compound, used as an disinfectant and for chemical synthesis.

Polyphenols like the flavonoids and tannins. Capsaicin, the pungent compound of chilli peppers. Tyrosinecarboxylic acid and cancer, an amino acid, carboxylic acid and cancer.

Cannot seem to locate a source. Tyrosol has also been found to protect cells of the central nervous system from dying after exposure to toxins like glutamate MSG and artificial sweeteners. This phenol antioxidant is, to my knowledge, not yet available as a supplement as of The neurotransmitters serotonindopamineadrenaline, and noradrenaline. Eugenol, the main constituent of the essential oil of clove.

Estradiol and other estrogens. Potential mechanisms of actions that may be involved in the neuroprotective effects of phenolic A ring compounds are: These signaling pathways may individually or collectively contribute to the plethora of neuronal cell carboxylic acid and cancer that are protected from a variety of insults by estrogen-like compounds.

Methyl salicylate, the major constituent of the essential oil of wintergreen. Raspberry ketone a compound with an intense raspberry smell. Salicylic acid is a phenolic compound Gallic acid, found in gallnuts. Ellagic acid Thymol 2-Isopropylmethyl phenolan antiseptic that is used in mouthwashes, carboxylic acid and cancer. BHT butylated hydroxytoluenea fat-soluble antioxidant and food additive.

Natural Substances with Phenolic acids Propolis is one of the few natural remedies that has maintained its popularity over a long period of time. The pharmacologically active molecules in the propolis are flavonoids and phenolic acids and their esters.

These components have multiple effects on bacteria, carboxylic acid and cancer and viruses. In addition, propolis and its components have anti-inflammatory and immunomodulatory activities. Moreover, propolis has been shown to lower blood pressure and cholesterol levels. However, clinical studies to substantiate these claims are carboxylic acid and cancer. Coffee is particularly rich in bound phenolic acids, such as caffeic acid, ferulic acidand p-coumaric acid.
