How do lipids go through the cell membrane? What makes lipids different from other organic compounds? Describe how carbohydrates, proteins, and fats are used to meet the energy needs of the body. How can a lipid be distinguished from a sugar?
The word 'lipid' (in several different spellings) has long been used to denote a chemically heterogeneous group of substances, having in common the property of insolubility in water, but solubility in non-polar solvents such as chloroform, hydrocarbons or alcohols. Adequate coverage of the whole...
It's composed of two layers of fatty molecules, called lipids. Embedded in the viral envelope are proteins from the host cell. There are also about 72 copies of so-called Env protein, which protrudes from the envelope surface. Env consists of a cap made of three or four molecules called ...
Dexamethasone phosphate (Dex-P) is the pro-drug of Dexamethasone (Dex). It undergoes conversion to Dex through the action of alkaline phosphatase. Both Dex-P and Dex are synthetic glucocorticoids derived from cortisol, a naturally occurring anti-inflammatory glucocorticoid. However, these drugs are ...
How do enzymes digest lipids? What modifications on proteins can be used to track the secretory process? What are Rab proteins? What are the associated proteins? Explain with an example. How are enzymes produced in a cell? What are some of the biological functions of proteins?
Biosurfactants are amphiphilic substances produced by microbial metabolism that contain both hydrophobic and hydrophilic groups, mainly composed of proteins, sugars, and lipids87. The structure of BS can be identified using various techniques such as thin layer chromatography, Fourier Transform Infrared Spec...
Additionally, flaxseeds are used to makeflaxseed oil, which is easily digested and a concentrated source of healthy fats. Another product of the flax plant (Linum usitatissimum) is linseed oil, which is boiled oil that’s used in oil-based paints, glazing putties (for windows) and as a wo...
The name liposome was derived from the two Greek words lipo meaning fat and soma meaning body, which perfectly describes these spherical objects that are made mainly from lipids. In some cases other constituents are added to modify their chemical and physical properties (Figure 9b). Liposomes are...
We have talked about nerve signals and mentioned that they are electrochemical in nature, but what does that mean? To understand how neurons transmit signals, we must first look at the structure of the cell membrane. The cell membrane is made of fats or lipids called phospholipids. Each phosph...
You’re used to a matte complexion (without shine) Sometimes these signs appear all over or only in one specific place, such as the nose or cheeks. Either way, a targeted skincare routine can help relieve dryness and set you on the path to smooth, comfortable skin. ...
