Apple seed oil oil, with the oil cake being used to supplement animal feed. Apple seeds are known to contain low concentrations (lower than apricot or almond seeds) of amygdalin, a compound that degrades into Hydrogen Cyanide (HCN) when metabolized. Apple seed oil Apple seed oil is a fixed oil found in apple seeds. It is used in the cosmetic and medical industries. A study on apple seed oil was conducted in 2007 which found that apple seeds contain a high amount of both oil and protein (27.5 to 28% and 33.8 to 34.5%, respectively).

Ground substance Ground substance Ground substance is an amorphous gel-like substance in the extracellular space that contains all components of the extracellular matrix (ECM) except for fibrous materials such as collagen and elastin. Ground substance is active in the development, movement, and proliferation of tissues, as well as their metabolism. Additionally, cells use it for support, water storage, binding, and a medium for intercellular exchange (especially between blood cells and other types of cells). Ground substance provides lubrication for collagen fibers. The components of the ground substance vary depending on the tissue. Ground substance is primarily composed of water, glycosaminoglycans (GAGs) such
