Trans fatty acid
An unhealthy substance that is made through the chemical process of hydrogenation of oils. Hydrogenation solidifies liquid oils and increases the shelf life and the flavor stability of oils and foods that contain them. Trans fatty acids are found in vegetable shortening and in some margarine, crackers, cookies, and snack foods. Trans fatty acids are also found in abundance in many deep-fried foods. Trans fatty acids both raise the ‘bad’ (LDL) cholesterol and lower the ‘good’ (HDL) cholesterol levels in blood, markedly increasing the risk of heart disease. Also known as trans fat.

- Transaminase clinical usage
Two of the better known enzymes in the transaminase class are serum glutamic oxaloacetic transaminase (SGOT) and serum glutamic pyruvic transaminase (SGPT). Both SGOT and SGPT are normally found primarily in liver and heart cells, are released into the bloodstream as the result of liver or heart damage, and so serve as tests of the […]
- Transaminase, serum glutamic oxaloacetic
An enzyme that is normally present in liver and heart cells, and is released into blood when the liver or heart is damaged. Blood SGOT levels are thus elevated with liver damage (for example, from viral hepatitis) or with an insult to the heart (for example, from a heart attack). Some medications can also raise […]
