What LDL and HDL Mean?
Digestion of Fat: During digestion, carbohydrates and proteins are dealt with first. By the time fat reaches the small intestine, it receives all the attention. Bile is squirted into the mixture to emulsify or break up the fat globules, allowing enzymes to attack the chemical bonds of the triglycerides. Fats are digested and broken down into fatty acids and glycerol, and pass into the intestinal cells.
Since you already know fat is not soluble in water, it needs a special transport system to move with blood and other body fluids: Fat can only move with helping protein particles, called lipoproteins.
There are 4 types of lipoproteins with very distinct jobs:
Chylomicrons are made by the intestines for transporting “new” fat to the body’s cells. These carry mostly triglycerides.
Very-Low-Density-Lipoproteins (VLDL) are made by the intestines and liver and transport fats around the body. These carry mostly triglycerides.
Low-Density Lipoproteins (LDL) are made by the liver to carry cholesterol to the body’s cells and tissues, and may form deposits on the walls of arteries and other blood vessels. They are therefore considered the lazy, or “bad,” cholesterol. The goal is to have an LDL level of < 100 milligrams per dL. What does your body need to make LDL’s? How is the Liver programmed to know when and how many LDL’s to make?
Protein : A chemical breakdown
All protein in your body is made up of amino acids. It is estimated that the human body has the ability to generate over 1 million different types of proteins. Believe it or not, 10,000 different proteins may exist in a single cell of your body AND each one requires a different arrangement of amino acids.
There are a total of 22 different types of amino acids. The body’s cells connect these amino acids to create each specific protein. Your body efficiently assesses with precision which protein is needed and produces it.More
