glycolipid/lipoprotein

Glycolipids are defined as

Lipids containing sphingosine base conjugated with carbohydrates

Major distribution of glycolipids

Nervous system and outer layer of cell membrane

Role of glycolipids in cell membranes

Cell adhesion and recognition

Cerebrosides are best described as

The simplest glycolipids

Structure of cerebrosides

Ceramide with either glucose or galactose instead of choline

Gangliosides are composed of

Ceramide, oligosaccharides, and sialic acid

Distribution of gangliosides

Ganglion cells of the central nervous system

Common feature of glycolipids in nervous tissue

They are important components of neuronal membranes

Failure of glycolipid degradation leads to

Lipid storage diseases

Lipoproteins are defined as

Complexes of lipids and proteins

Lipid components of lipoproteins

Phospholipids, cholesterol, cholesterol esters, fatty acids, and triacylglycerols

Plasma lipoproteins are classified based on

Density or electrophoretic mobility

Major classes of plasma lipoproteins

Chylomicrons, VLDL, LDL, and HDL

Chylomicrons are classified as

A plasma lipoprotein type

VLDL stands for

Very low density lipoproteins

LDL stands for

Low density lipoproteins

HDL stands for

High density lipoproteins
