Lipid Digestion

Lipid Digestion

Lipids are large molecules that are generally not water-soluble. Since most of the digestive enzymes in the human body are water-based, there are specific steps the body must take to break down lipids and make them available for use.

Protein-protein Interfaces

Protein-protein Interfaces

Many proteins form complexes to carry out their functions, making protein-protein interactions (PPIs) essential for an organism's survival. Most PPIs are stabilized by numerous weak noncovalent chemical forces. The physical shape of the interfaces determines the way two proteins interact. Many globular proteins have closely-matching shapes on their surfaces, which form a large number of weak bonds. Additionally, many PPIs occur between two helices or between a surface cleft and a polypeptide...

Lipids as Anchors

Lipids as Anchors

In the plasma membrane, the lipids forming the bilayer can also act as an anchor to tether proteins to the membrane. The three main types of lipid anchors found in eukaryotes are – prenyl groups, fatty acyl groups, and glycosylphosphatidylinositol or GPI groups. Prenyl and fatty acyl groups act as anchors on the cytosolic surface of the membrane, whereas GPI anchors proteins on the extracellular side.
The carboxy-terminal of most of the prenylated proteins, such as Ras proteins, contains the...

Assembly of the Lipid Bilayer in the ER

Assembly of the Lipid Bilayer in the ER

Biological membranes are more than just a barrier separating cell cytoplasm from the outside environment. They are highly dynamic and help maintain the integrity and physiological stability of the cells as well as membrane-bound organelles. Membranes also play vital roles in cell-to-cell and intracellular communication.
A large chunk of any biological membrane is composed of phospholipids. These lipids have a heterogeneous distribution across different subcellular organelles and even between...

Area of Science:

Biochemistry
Enzymology
Interface Science

Background:

Lipases are crucial acyl hydrolases for fat digestion, catalyzing triglyceride hydrolysis at oil-water interfaces.
Lipase function is influenced by interfacial composition, a poorly understood factor termed 'interfacial quality'.

Purpose of the Study:

To elucidate the impact of interfacial microenvironment on lipase catalysis.
To investigate lipolysis as a self-regulated process for controlling enzyme activity.

Main Methods:

Biophysical approaches to analyze interfacial properties.
Characterization of interfacial composition during triglyceride digestion.
Oil hydrolysis experiments in a model gastro-intestinal system.

Main Results:

Lipase activity is primarily affected by substrate accessibility at the interface, not enzyme denaturation.
Lipolysis exhibits self-regulation, influenced by the interfacial properties of reaction components.
Interfacial engineering in a model system demonstrated control over enzyme reactivity.

Conclusions:

Interfacial composition significantly modulates lipase catalysis by controlling substrate accessibility.
Lipolysis is a self-regulated reaction offering novel control mechanisms.
This research provides a new framework for understanding and controlling lipase reactions at interfaces, with implications for biotechnology and healthcare.
