Allicin is an organosulfur compound obtained from garlic and leeks. [1] When fresh garlic is chopped or crushed, the enzyme alliinase converts alliin into allicin, which is responsible for the aroma of fresh garlic. [2] Allicin is unstable and quickly changes into a series of other sulfur-containing compounds such as diallyl disulfide. [3]
Alliin / ˈ æ l i. ɪ n / is a sulfoxide that is a natural constituent of fresh garlic. [1] It is a derivative of the amino acid cysteine.When fresh garlic is chopped or crushed, the enzyme alliinase converts alliin into allicin, which is responsible for the aroma of fresh garlic.
A bioactive compound is a compound that has an effect on a living organism, tissue or cell, usually demonstrated by basic research in vitro or in vivo in the laboratory. While dietary nutrients are essential to life, bioactive compounds have not been proved to be essential – as the body can function without them – or because their actions are obscured by nutrients fulfilling the function.
Ajoene / ˈ ɑː h oʊ. iː n / is an organosulfur compound found in garlic (Allium sativum) extracts. It is a colorless liquid that contains sulfoxide and disulfide functional groups. The name [ 1 ] (and pronunciation) is derived from "ajo", the Spanish word for garlic.
Garlic breath is allegedly alleviated by eating fresh parsley. Abundant sulfur compounds in garlic are also responsible for turning garlic green or blue during pickling and cooking. Under these conditions (i.e., acidity, heat) the sulfur-containing compound alliin reacts with common amino acids to make pyrroles, clusters of carbon-nitrogen rings.
When a garlic clove is crushed, the enzyme alliinase is released forming allicin from the cysteine sulfoxide alliin. Allicin breaks down into additional organosulfur compounds. In the presence of oil or organic solvents, among the compounds formed are the isomeric vinyldithiins and ajoene.
S-Allylcysteine (SAC) is an organosulfur compound that has the formula HO 2 CCH(NH 2)CH 2 SCH 2 C=CH 2. It is the S-allylated derivative of the amino acid cysteine. As such only the L-enantiomer is significant biologically. SAC constituent of aged garlic.
Bioactive agents are substances that can influence an organism, tissue or cell. Examples include enzymes, drugs, vitamins, phytochemicals , and bioactive compounds . Bioactive agents can be incorporated into polymers , [ 1 ] [ 2 ] which has applications in drug delivery and commercial production of household goods and biomedical devices. [ 2 ]
