What is p-Coumaric acid used for?

What is p-Coumaric acid used for?

Coumaric acid (CA) is a phenolic acid of the hydroxycinnamic acid family, and it has many biological functions such as anti-oxidant, anti-inflammatory, antidiabetic, anti-ulcer, anti-platelet, anti-cancer activities, etc.

What does P stand for in P Coumaric?

p-Coumaric acid. Names. Preferred IUPAC name. (2E)-3-(4-Hydroxyphenyl)prop-2-enoic acid. Other names.

Is phenol good for skin?

If phenol is left on the skin, it will penetrate rapidly and lead to cell death and gangrene. If more than 60 square inches of skin are affected, there is risk of imminent death. Phenol appears to have local anesthetic properties and can cause extensive damage before pain is felt.

What is the pH of gallic acid?

We found that gallic acid produces two different radicals as a function of pH. In the pH range between 7-10, the spectrum of the gallate free radical is a doublet of triplets (aH = 1.00 G, aH = 0.23 G, aH = 0.28 G). This is consistent with three hydrogens providing hyperfine splitting.

What is formula of cinnamic acid?

C9H8O2Cinnamic acid / Formula

Cinnamic acid is a white crystalline acid with a molecular formula C9H8O2. It is a crystalline compound that is white in colour and is slightly soluble in water.

Is phenol safe for humans?

Exposure to phenol may cause irritation to the skin, eyes, nose, throat, and nervous system. Some symptoms of exposure to phenol are weight loss, weakness, exhaustion, muscle aches, and pain. Severe exposure can cause liver and/or kidney damage, skin burns, tremor, convulsions, and twitching.

Why is phenol bad in skincare?

“Phenol can cause burns,” she explains. “That’s why when you apply the product, it stings. The company says it’s proof that it’s working, but actually it’s proof that you’re causing damage to your skin.” Fanzani is also wary of the potential long-term effects that could come from using the product.

Is phenol safe on skin?

Overview. The major hazard of phenol is its ability to penetrate the skin rapidly, causing severe burns. Toxic and even fatal amounts of phenol can be absorbed through relatively small areas of skin. Due to its local anesthetizing properties, skin burns may be painless.

Is gallic acid a phenol?

Gallic acid is a natural phenolic compound found in several fruits and medicinal plants. It is reported to have several health-promoting effects.

What is gallic acid good for?

Gallic acid is a phenolic acid found in plants, especially fruits, nuts, wine, and tea. It has antioxidant, antimicrobial, and potentially even anti-obesity properties. Through its main mechanisms, it may be particularly beneficial for conditions like cancer and brain health.

Is tannin acidic or alkaline?

They are used chiefly in tanning leather, dyeing fabric, and making ink and in various medical applications. Tannin solutions are acidic and have an astringent taste. Tannins are responsible for the astringency, colour, and some of the flavour in black and green teas.

What is the pH of tannic acid?

around 6
Tannic acid is a specific form of tannin, a type of polyphenol. Its weak acidity (pKa around 6) is due to the numerous phenol groups in the structure.

What is hydroxycinnamic acid made of?

Hydroxycinnamic acids are generally composed of a carbon backbone that varies in length from C6 to C3 with a variety of substituents such as caffeic acid, chlorogenic acid, and quinic acid. Hesham R. El-Seedi, Ulf Göransson, in Studies in Natural Products Chemistry, 2018

What are the hydroxycinnamic esters present in grapes?

The predominant hydroxycinnamic ester in grape is always trans- caftaric acid (0.06–0.78 mg per gram fresh weight of skin), followed by trans-p -coutaric acid (0–0.3 mg per gram fresh weight of skin), and trans- fertaric acid is present only in low amounts.
