In many cases the association process is a part of biological function as in blood clotting or the formation of muscle fibers. Aggregation of proteins also leads to perturbation of the biological function with sometimes serious physiological consequences as in the formation of cataracts in the lens of the eye or amyloid fibrils associated with Alzheimer’ and other neurological diseases. From a colloid chemistry perspective, protein self-association is a special case of the general problem of colloid stability. There are two important aspects of the protein systems in this respect: first in contrast to colloids in general the system can be obtained in pure form and then represent a true single component. Second the protein has a complex molecular structure and one should expect protein- protein interactions to be highly directional.
The metabolic rewiring is the result of genetic and genomic alterations in oncogenes( genes that transform normal cells into tumor cells) and tumor suppressor genes (genes that are antioncogenetic) which are responsible for cell signaling. Recent research shows a possibility that these altered metabolic pathways fundamentally drive tumor growth rather than being just a result of cancer. The development of cancer metabolism inhibitors and the possibility combining them with other cancer therapies in vogue could have a profound impact on cancer
Carbohydrates are important because they are a source of immediate energy and controls structure of cells such as cell wall etc. Without this source of energy the animal body could not carry out the functions properly so this is why carbohydrates are so important. Now proteins have many uses for example enzymes and transport proteins. Proteins provide support for example keratin which gives structure to hair and nails. From the information I have gathered it will show you my point of view and my reason why I believe these are the two most important
Sphingolipids and the CNS Sphingolipids encompass a complex range of membrane lipids in which a fatty acid is linked to a long sphingosine carbon backbone, primarily C18-sphinganine (18:0) and C18-sphingosine (C18:1) in mammals. Figure 1 shows a schematic representation of the sphingolipid metabolic pathway. Ceramide is central in sphingolipid metabolism and is produced by de novo and recycling pathways.37 In de novo synthesis, serine and palmitoyl-CoA are substrates of serine palmitoyl-transferase (SPT), the rate limiting enzyme that generates ketosphinganine (bottom). Ketosphinganine is reduced to form sphinganine, which is then N-acylated with fatty acids of different chain lengths by ceramide synthases (CerS), producing dihydroceramides.
Proteins are complex macromolecules that are formed by elements carbon, hydrogen, oxygen and nitrogen. Proteins composed of one or more polypeptide chains of amino acids. The main functions of proteins are to structure, support, protect, make movement, catalyst, transport and make hormones in human body. In the structural role, collagen and elastin provide support for connective tissue. Actin and myosin are proteins that involved in muscle contraction and movement.
Background: Macromolecules are organic molecules that are necessary for life, these molecules include nuclei acids, carbohydrates, proteins, and lipids. Carbohydrates are the bodies main source of energy, but they 're in the wrong forms, for example lactose, which was used in the lab. Enzymes are used to break down the carbohydrates into simpler components that are easily digested and converted into energy. The purpose of this lab was to show how specific enzymes are, and how enzymatic
However, if not used properly, science can also create problems to healthcare provision. It is therefore of great importance to come up with ways that scientific applications can be used to enhance service delivery and for the improvement of health for different communities across the globe.

DNA stand for deoxyribonucleic acid. RNA stands for ribonucleic acid. They share some similarities, such as both being nucleic acids. Nucleic acids are long macromolecules that consist of a long chain of nucleotides. Both DNA and RNA have five carbon sugar and four nitrogen containing bases.
It can help scientists understand the development of deadly diseases, and help them find better ways to prevent them. Cloning can be used as stem cells to be used to take place of tissue that some people need in parts of their body. This process can be the future of preventing death, by making new
However, despite the previous arguments, the negative effects that come with gene therapy outweigh the positive connotations. There are two types of gene therapy, somatic and germline. Both of them raise unethical questions, but germline therapy needs to be taken into account of. Germline therapy is “when DNA is transferred into the cells that produce reproductive cells, eggs or sperm, in the body. This type of therapy allows for the correction of disease-causing gene variants that are certain to be passed down from generation to generation” (“Is germline gene therapy ethical,” 2015).
