To review:
The diet group having highest LDL (low-density lipoprotein) to HDL (high-density lipoprotein) ratio. The results of the study are shown in the table given below:
Effect of Diet on Lipoprotein levels (mg/dL or milligram per deciliter) | ||||
cis Fatty acids | Trans Fatty acids | Saturated Fats | Optimal level | |
LDL | 103 | 117 | 121 | <100 |
HDL | 55 | 48 | 55 | >40 |
LDL-to-HDL ratio | 1.87 | 2.43 | 2.2 | <2 |
Introduction:
Lipoproteins are made up of proteins and lipids. These molecules help in the transportation of lipids (mainly cholesterol) in the blood or extracellular fluid. The phospholipids are present on the exterior while other lipids lie in the interior. Phospholipids are oriented in such a way that the hydrophilic part is on the outer side while the hydrophobic part is on the inner side.
On basis of density, lipoproteins are classified as Ultra Low-Density Lipoproteins (ULDL), Intermediate Density Lipoproteins (IDL), Very Low-Density Lipoproteins (VLDL), LDL, and HDL. The LDL and HDL are of clinical importance and are classified as bad cholesterol and good cholesterol, respectively.

- Molecular Biology Question You are working to characterize a novel protein in mice. Analysis shows that high levels of the primary transcript that codes for this protein are found in tissue from the brain, muscle, liver, and pancreas. However, an antibody that recognizes the C-terminal portion of the protein indicates that the protein is present in brain, muscle, and liver, but not in the pancreas.
