What are phenolics in fruits?
Phenolic compounds are secondary metabolites widely found in fruits, mostly represented by flavonoids and phenolic acids. The growing interest in these substances is mainly because of their antioxidant potential and the association between their consumption and the prevention of some diseases.
What is food phenolics?
Highlights: Phenols or Phenolics is a designation corresponding to compounds that have one or more hydroxyl groups attached to a 6-carbon aromatic ring. Phenols in foods occur mainly as secondary metabolites of vegetables, often found in polymeric forms (polyphenols).
What are phenolics in plants?
Phenolics are aromatic benzene ring compounds with one or more hydroxyl groups produced by plants mainly for protection against stress. The functions of phenolic compounds in plant physiology and interactions with biotic and abiotic environments are difficult to overestimate.
What are examples of phenolic acids?
Examples of Phenolic Acids
- Protocatechuic acid (PCA)
- p-hydroxybenzoic acid (PHBA)
- Vanillic acid.
- Caffeic acid.
- p-Coumaric acid.
- Ferulic acid.
- Syringic acid.
- Sinapinic acid.
What are the types of phenolics?
Occurrence of Phenolics There are two classes of phenolic acids, hydroxybenzoic acids and hydroxycinnamic acids.
What are simple phenolics?
Simple phenols (1) are described as compounds having at least one hydroxyl group attached to an aromatic ring as a basic skeleton. Within the class of simple phenols are phenol (6), catechol (7), resorcinol (8), and phloroglucinol (9).
What are phenolic acids used for?
Phenolic acids, readily absorbed through intestinal tract walls, are beneficial to human health due to their potential antioxidants and avert the damage of cells resulted from free-radical oxidation reactions. On regular eating, phenolic acids also promote the anti-inflammation capacity of human beings.
What are phenolic amino acids?
Two amino acids, serine and threonine, contain aliphatic hydroxyl groups (that is, an oxygen atom bonded to a hydrogen atom, represented as ―OH). Tyrosine possesses a hydroxyl group in the aromatic ring, making it a phenol derivative.
