Triglycerides and Phospholipids Lecture

These flashcards cover key concepts about triglycerides and phospholipids based on lecture notes.

What are triglycerides?

Triglycerides are a type of fat found in the blood, formed from a molecule of glycerol and three molecules of fatty acids.

What is a normal level of triglycerides in the blood?

Normal triglyceride levels are less than 150 mg/dL or 1.7 millimoles per liter.

When are triglycerides considered high?

Triglycerides are considered high when levels are greater than 200 mg/dL to 500 mg/dL or 2.3 to 5.6 millimoles per liter.

What health risks are associated with high triglyceride levels?

High triglyceride levels are associated with increased risk of heart disease, obesity, uncontrolled diabetes, atherosclerosis, and stroke.

What diet factors contribute to high triglyceride levels?

Regular alcohol use, a high-calorie diet, and excessive consumption of simple sugars can contribute to high triglyceride levels.

What is the correlation between triglycerides and cardiovascular disease?

High levels of triglycerides can be an independent risk factor for cardiovascular diseases when associated with low HDL and high LDL.

What role does physical activity play in triglyceride levels?

Physical activity can lower triglyceride levels, with effects varying based on intensity, duration, and baseline triglyceride levels.

What are phospholipids?

Phospholipids are complex lipids that contain one or more phosphate groups, and are key components of cell membranes.

What is the most abundant class of phospholipids?

Glycerophospholipids are the most abundant class of phospholipids found in nature.

How do glycolipids function in cellular processes?

Glycolipids act as signal transducers and are involved in cell proliferation, binding pathogenic bacteria, and calcium homeostasis.
