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.
Types of hydrocarbons. A hydrocarbon can exist as a gas (propane or methane), liquid (benzene or hexane), waxes or low melting solids (like naphthalene) or polymers (like polyethylene). There are four types of hydrocarbons namely saturated hydrocarbons, unsaturated hydrocarbons, cycloalkanes and aromatic hydrocarbons.nsaturated hydrocarbon Hydrocarbons having one or more double or triple bonds between carbon atoms are called unsaturated hydrocarbons. Alkenes are the hydrocarbons that have one, double bond between the carbon atoms. On the other hand, those that contain triple bonds are alkynes.
