Invasive Ductal Carcinoma (IDC). Invasive ductal carcinoma (IDC), also known as infiltrating ductal carcinoma, is cancer that began growing in the duct and has invaded the fatty tissue of the breast outside of the duct. IDC is the most common form of breast cancer, representing 80 percent of all breast cancer diagnoses.nvasive ductal carcinoma (IDC), also known as infiltrating ductal carcinoma, is cancer that began growing in the duct and has invaded the fatty tissue of the breast outside of the duct.
An alkene is a hydrocarbon containing double bonds. An alkyne is a hydrocarbon containing triple bonds. Ethene, C 2 H 4, is an example of an unsaturated hydrocarbon with a double bond.ethyne (acetylene), C 2 H 2 is an example of an unsaturated hydrocarbon with a triple bond.thene, C 2 H 4, is an example of an unsaturated hydrocarbon with a double bond. ethyne (acetylene), C 2 H 2 is an example of an unsaturated hydrocarbon with a triple bond.
Alkenes. Alkenes are unsaturated hydrocarbons that have one or more carbon-carbon double bond, with a general structure of (R-C=C-R'), where R and R' are hydrocarbon groups attached to either side of the carbon atoms.ydrocarbons are compounds that only consist of the elements hydrogen and carbon. In this lesson, we will focus on one type of hydrocarbon: unsaturated hydrocarbons, and its three types-alkenes, alkynes and aromatic hydrocarbons.
