Occasionally, aqueous ethanol or glycerol may be used instead of water. [2] Decoction can be used to make tisanes , tinctures and similar solutions. Decoctions and infusions may produce liquids with differing chemical properties, as the temperature or preparation difference may result in more oil-soluble chemicals in decoctions versus infusions.
Formononetin is found in a number of plants and herbs such as red clover. [1] Along with other phytoestrogens, it predominantly occurs in leguminous plants and Fabaceae, particularly in beans, such as green beans, lima beans, soy and many others, as the free aglycone or in form of its glucoside ononin.
They are water-soluble anions and belong to the glucosides. Every glucosinolate contains a central carbon atom, which is bound to the sulfur atom of the thioglucose group, and via a nitrogen atom to a sulfate group (making a sulfated aldoxime). In addition, the central carbon is bound to a side group; different glucosinolates have different ...
The protein is made up of at least three different subunits and varies according to the species of algae that produces it. The subunit structure of the most common R-PE is (αβ) 6 γ. The α subunit has two phycoerythrobilins (PEB), the β subunit has 2 or 3 PEBs and one phycourobilin (PUB), while the different gamma subunits are reported to ...
The structure is stabilised by disulfide bridges linking the helices to each other. The structure forms an internal hydrophobic cavity in which 1-2 lipids can be bound. The outer surface of the protein is hydrophilic, allowing the complex to be soluble. The use of hydrophobic interactions, with very few charged interactions, allows the protein ...
The peridinin-chlorophyll-protein complex (PCP or PerCP) is a soluble molecular complex consisting of the peridinin-chlorophyll a-protein bound to peridinin, chlorophyll, and lipids. The peridinin molecules absorb light in the blue-green wavelengths (470 to 550 nm) and transfer energy to the chlorophyll molecules with extremely high efficiency.
Ascorbate is a known cofactor of myrosinase, serving as a base catalyst in glucosinolate hydrolysis. [1] [7] For example, myrosinase isolated from daikon (Raphanus sativus) demonstrated an increase in V max from 2.06 μmol/min per mg of protein to 280 μmol/min per mg of protein on the substrate, allyl glucosinolate (sinigrin) when in the presence of 500 μM ascorbate.

Silibinin (), also known as silybin (both from Silybum, the generic name of the plant from which it is extracted), is the major active constituent of silymarin, a standardized extract of the milk thistle, containing a mixture of flavonolignans consisting of silibinin, isosilibinin, silychristin, silidianin, and others.
