[Function]

Grapes (Vitis vinifera) have been heralded for their medicinal and nutritional value for thousands of years. Egyptians ate grapes a very long time back, and several ancient Greek philosophers spoke about the healing power of grapes — usually in the form of wine. European folk healers made an ointment from the sap of grapevines to treat skin and eye diseases. Grape leaves were used to stop bleeding, inflammation, and pain, such as the kind brought on by hemorrhoids. Unripe grapes were used to treat sore throats, and dried grapes (raisins) were used for constipation and thirst. Round, ripe, sweet grapes were used to treat a range of health problems including cancer, cholera, smallpox, nausea, eye infections, and skin, kidney, and liver diseases.

Grape seed extracts are industrial derivatives from whole grape seeds that have a great concentration of vitamin E, flavonoids, linoleic acid and phenolic OPCs. The typical commercial opportunity of extracting grape seed constituents has been for chemicals known as polyphenols having antioxidant activity in vitro.

“Lysozyme is a small enzyme that binds to polysaccharide chains and breaks them apart by hydrolysis. It has two structural domains. One domain is composed mostly of alpha helices, while the other domain is composed mostly of beta strands. The interface between the two domains forms a cleft in which the substrate binds. The structure shown here contains one of the products of the hydrolysis reaction. Lysozyme acts as a catalyst by adding a molecule of water to the bond between two sugars, breaking the bond. This reaction is catalyzed by two strategically positioned amino acid side chains in the enzymes active site: glutamate 35 and aspartate 52. The highlighted group on the reaction product shown here would have formed the bond cleaved in the reaction.”
