In abnormal glycosylation, molecules of glucose or other carbohydrates in living organisms are inappropriately attached to proteins, which causes protein denaturation. Abnormal glycosylation modification is known to directly or indirectly affect the tumor escape process, but very few studies have been ...
Royal jelly (RJ) is a nutrient-rich source of bioactive compounds that are essential to many biological processes. About (60–70% w/w) water, (9–18% w/w) proteins, (7–18% w/w) carbohydrates, and (3–8% w/w) lipids make up the majority of RJ. Minor components also found in...
What is the difference in function between carbohydrates,lipids and starch? What role does the squid play in the ocean ecosystem? What adaptations does the squid have that allow it to play that role? Explain the difference between chromatins and chromatids, and what part of the DNA each of ...
Organisms living in terrestrial ecosystems must be able to adapt to dry conditions that result from shifts in water availability due to diurnal and seasonal fluctuations1,2,3. Plants, as sessile organisms, have adapted strategies to tolerate, resist, or avoid the stress imposed by drying environmen...
The foundation of any ecosystem is the primary source of energy: sunlight. Plants and other photosynthesizing organisms use light energy from the sun – together with water and carbon dioxide – to produce carbohydrates that they use for energy. These organisms are calledautotrophs, meaning they ...
The cell cycle is the process through which the cells of living organisms divide and grow. It can be divided into two interphases (the G1 and G2 phases), one DNA replication phase (the S phase), and one mitotic phase i.e., the M phase....

Summarize the digestion and absorption of carbohydrates. How do enzymes digest lipids? Which of the following is not true of the human appendix? a) It has no known role in human digestion. b) It is a pouch of the large intestine. c) It is the primary site where symbiotic bacteria break...
In brown rot fungi, the mechanism of the attack on the lignocellulose complex consists in selective removal of carbohydrates. This two-step action combines non-enzymatic activity prior to enzymatic hydrolysis. Non-enzymatic depolymerisation of wood cell wall polysaccharides involves low molecular weight ...
Using cellulose and chitin as examples, describe the features of the polymeric "structural" carbohydrates. Discuss where they occur in nature, and what gives these molecules the required rigidity to serve as structural materials. Describe the function an...
