Insights

Small for gestational age (SGA) neonates exhibit altered lipoprotein profiles, with higher triglycerides and lower HDL(2)-cholesterol. This may be linked to increased cholesteryl ester transfer, potentially explaining later coronary heart disease risks.

Area of Science:

  • Neonatal metabolic health
  • Lipoprotein metabolism
  • Cardiovascular disease risk factors

Background:

  • In utero undernourishment can cause lasting metabolic, endocrine, and immune changes.
  • Birth weight influences neonatal health and long-term disease risk.
  • Cholesteryl ester transfer protein (CETP) affects lipoprotein profiles and atherosclerosis risk.

Purpose of the Study:

  • To investigate the impact of birth weight on neonatal lipoprotein profiles.
  • To determine the role of CETP in neonates with varying birth weights.
  • To understand the relationship between neonatal metabolic changes and future cardiovascular risk.

Main Methods:

  • Compared lipoprotein profiles, including triglyceride (TG) and high-density lipoprotein (HDL)(2)-cholesterol levels, in neonates based on birth weight.
  • Measured CETP mass using ELISA and CETP activity using exogenous lipoproteins.
  • Quantified cholesteryl ester (CE) transfer from HDL to apolipoprotein B lipoproteins.

Main Results:

  • Small for gestational age (SGA) neonates had the highest TG and lowest HDL(2)-cholesterol levels.
  • SGA neonates showed the lowest CETP mass but the highest cholesteryl ester transfer.
  • No significant differences in CETP activity were observed among neonates.

Conclusions:

  • Neonatal nourishment levels in utero significantly impact lipoprotein profiles and CETP.
  • Increased cholesteryl ester transfer in SGA neonates may contribute to their elevated risk of coronary heart disease (CHD).
  • Altered neonatal lipid metabolism is a potential predictor of later-life cardiovascular health.

Overview of Fatty Acid Metabolism01:28

Overview of Fatty Acid Metabolism

Lipids also are sources of energy that power cellular processes. Like carbohydrates, lipids are composed of carbon, hydrogen, and oxygen, but these atoms are arranged differently. Most lipids are nonpolar and hydrophobic. Major types include fats and oils, waxes, phospholipids, and steroids.
Fatty acids are catabolized in a process called beta-oxidation, which takes place in the matrix of the mitochondria and converts their fatty acid chains into two-carbon units of acetyl groups. The acetyl...
Synthesis of Phosphatidylcholine in the ER Membrane01:27

Synthesis of Phosphatidylcholine in the ER Membrane

The ER synthesizes lipids for building cell membranes and performing cellular functions such as energy storage and signaling. The lipid synthesis machinery embedded in the ER membrane primarily collects all reactants from the cytosol. Following synthesis, the secretory pathway and the ER contact sites distribute these lipids to other cellular organelles. Additionally, the energy-rich triacylglycerides are transported from the ER via lipid droplets.
The major components of all eukaryotic cell...

Cholesterol: Significance and Regulation

Although not a source of energy, cholesterol plays a significant role as a foundational structure for bile salts, steroid hormones, and vitamin D, as well as being a crucial component of plasma membranes. Approximately 15% of blood cholesterol is derived from our diet, with the remainder synthesized from acetyl CoA by the liver and intestines. Cholesterol is eliminated from the body through its conversion into bile salts, which are eventually discarded in the feces.
Considering cholesterol and...
Lipid Absorption01:24

Lipid Absorption

Dietary triglycerides from chyme in the duodenum are mixed with bile salts produced by the liver to emulsify fats. As a result, large droplets are broken down into smaller ones, increasing the surface area for enzymatic action. Once emulsified, pancreatic lipases hydrolyze the triglycerides into free fatty acids and monoglycerides.
These breakdown products bind with bile salts and lecithin to form micelles, which quickly pass between microvilli to come in close contact with the apical...

Blood Studies for Cardiovascular System III: Serum Lipid Profile

Understanding serum lipids is crucial for maintaining cardiovascular health and preventing heart disease and stroke.
Serum lipids are fats and fatty substances in the blood and are crucial for various bodily functions, including energy storage, cellular structure, and hormone production. Serum lipids consist of cholesterol, triglycerides, and phospholipids.
Cholesterol is a soft, fat-like substance found in all body cells. It is crucial for producing hormones, vitamin D, and substances that aid...
