A cell can replicate itself independently. Hence, they are known as the building blocks of life. Each cell contains a fluid called the cytoplasm, which is enclosed by a membrane. Also present in the cytoplasm are several biomolecules like proteins, nucleic acids and lipids. Moreover, cellular...
Lipids are large organic molecules or "macromolecules." Due to their association with dietary fat, lipids won't win many popularity contests. But lipids are important for more than growing waistlines. Lipids function in energy storage, cell membrane structure, protection of living surfaces and chemic...
“Association of nutrients with blood lipids in 19 countries and 5 continents: the PURE study.” Global Heart. 11.2S (2016): e6.“Dietary Reference Intakes for Energy, Carbohydrate, Fiber, Fat, Fatty Acids, Cholesterol, Protein, and Amino Acids.” Institute of Medicine, Food and Nutrition ...
Non-uniformityis another important feature of cell membranes. The membranes include specialized molecules such as lipid rafts and specialized protein complexes. Lipid rafts are small, transient areas of specific lipids in the cell membrane that can help signal critical cell processes such asendocytosis,...
What cell type creates myelin within the peripheral nervous system? Does the presynaptic membrane have a myelin sheath? Is the myelin sheath associated only with axons? What does nicotine do to the myelin sheath in adults? Does myelin sheath have lots of lipids? Are myelin sheaths on the axons...
30 When given a high-fructose or a HFD for 13 weeks, the HFD caused the largest changes in serum lipids and lipid accumulation in the liver and kidney in young (4-weeks old) rats, whereas the high-fructose diet increased visceral lipid stores, mean arterial pressure and heart rate in ...

Carbohydrates and lipids store energy in the cell, form structural components and act as chemical messengers. Proteins perform similar roles but also set off the chemical reactions that make life possible and affect gene activity. Nucleic acids store the organism’s entire genetic code. ...
“Clinical levels of antibiotics can cause oxidative stress that can lead todamage to DNA, proteins and lipids in human cells, but this effect can be alleviated byantioxidants. Taking antibiotics renders individuals susceptible to diseases and conditions by leaving them in what is termed a ...
Scientists from these companies have found a way to genetically modify algae and double the production of fatty lipids. As a result, the amount of biofuel that can be produced from algae doubles as well. The companies are optimistic that the next phase of their research program could enable ...
