Proteins, carbohydrates, and lipids are the three main types of biomolecules. Proteins are made of amino acid chains and perform most bodily functions. Carbohydrates are the main energy source and come in simple and complex forms. Lipids include fats, oils, waxes, and other fatty substances that serve as energy stores and membrane components. Nucleic acids DNA and RNA carry genetic information and aid in protein synthesis. Enzymes are protein catalysts that speed up biochemical reactions and have various roles in industrial and biological processes.
This document provides an overview of important biomolecules and their structures and functions. It discusses that organic compounds in cells contain carbon and functional groups. The four major classes of biological molecules are carbohydrates, lipids, proteins, and nucleic acids. These molecules are often polymers formed from linking simple monomers together. Carbohydrates function in energy storage, lipids in energy storage and signaling, proteins in structure and function, and nucleic acids in information storage and transfer. Molecular structure determines biological function.
Lipids are fatty substances that are insoluble in water but soluble in organic solvents. They serve important structural and energy storage functions in the body. There are three main classes of lipids: simple lipids like fatty acids and triglycerides, compound lipids including phospholipids, and steroids such as cholesterol. Cholesterol is an important component of cell membranes and a precursor for bile acids, vitamin D, and steroid hormones. Cholesterol is transported through the bloodstream within lipoproteins, with LDL cholesterol increasing risk of atherosclerosis and HDL cholesterol protecting against it through reverse cholesterol transport.

Unjustly Incriminating Bacteria: the Role of Bacteriophages in Bacterial Infe...christianagboeze2427
油
SUMMARY
Based on human relationship with bacteria, virulence is one of the most important case to us. Some forms of virulence thought to arise only from the actions of bacteria are not actually caused by them but are indirectly influenced by another counterpart in the microbial mix of the ecosystem called bacteriophage; viruses that only infect prokaryotes such as bacteria but not eukaryotes. Bacteriophages preferably attack bacteria due to the lack of specific receptors for phages on eukaryotic cells which are found in bacteria e.g. peptide sequences and polysaccharide moieties in gram positive and gram negative bacteria, bacterial capsules, slime layers, flagella etc. They recognize and bind to bacteria using appropriate receptors, subsequently proceeding to inject their genome called prophage into their host. This review focuses on the most probable outcomes of phage-host interactions via the lytic and lysogenic cycles which are therapeutic effect and pathogenicity/resistance to antibiotics respectively. By lysogenic conversion or transfer of acquired genetic materials via transduction, phages can confer unusual traits such as virulence and antibiotics resistance. Important pathogenic bacteria that cause persistent and critical infections which have their pathogenicity engineered by phages include Pseudomonas aeruginosa, Salmonella enterica, Escherichia coli, Vibrio cholerae, Staphylococcus spp., and Clostridium spp.
The prophages influence their virulence in a variety of ways which include: contribution to the production of phage-encoded toxins, modification of the bacterial envelope, mediation of bacterial infectivity, and control of bacterial cell regulation. The unwavering threat of antimicrobial resistance in global health, extreme difficulty involved in developing novel antibiotics, and the rate at which microorganisms develop resistance to newly introduced antimicrobials have sparked urgency and interest in research for effective methods to eradicate pathogenic bacteria and limit antibiotic resistance. As a result, interest in phage therapy has been reignited because of the high efficiency in detecting and killing pathogenic bacteria by phages.

PROTEIN DEGRADATION via ubiquitous pathawayKaviya Priya A
油
Protein degradation via ubiquitous pathway In general science, a ubiquitous pathway refers to a biochemical or metabolic pathway that is:
1. *Widely present*: Found in many different organisms, tissues, or cells.
2. *Conserved*: Remains relatively unchanged across different species or contexts.
Examples of ubiquitous pathways include:
1. *Glycolysis*: The process of breaking down glucose for energy, found in nearly all living organisms.
2. *Citric acid cycle (Krebs cycle)*: A key metabolic pathway involved in energy production, present in many cells.
3. *Pentose phosphate pathway*: A metabolic pathway involved in energy production and antioxidant defenses, found in many organisms.
These pathways are essential for life and have been conserved across evolution, highlighting their importance for cellular function and survival.

It ensures precise characterization, detecting structural variations, impurities, and post-translational modifications, ensuring biosimilar quality, efficacy, and regulatory compliance in pharmaceutical development.
3. BIOMOLECULES
BIOLOGICAL MACROMOLECULES
The term molecule refers to very large molecules and something that consists of
more than one atom. Herman Staudinger coined it in 1920. Macromolecules are
so huge that these are made up of more than 10,000 atoms.
Macromolecules are also termed as polymers. They are formed by the
polymerization of molecules such as carbon, hydrogen and oxygen. The
monomer units of macromolecules are polar in nature, with their heads and tails
with different physical and chemical properties.

LIPIDS
Lipids come from the Greek word lipos meaning fat.
Lipids are family of biomolecules group together
because of its property of being hydrophobic (water-
fearing). Lipids are non-polar molecules mak?ing it
soluble to non-polar solvents like acetone, ether and
benzene.

29. SATURATED UNSATURATED
Saturated fatty acid is a straight
chain where all the carbon atoms in
the chain have two hydrogen singly
bonded to making the molecules to
form a strong attraction.
Unsaturated fatty acid on the other
hand, tends to bend due to the
presence of a double bond in one of
the carbon in the chain. The
molecule will not be as close as that
of the saturated fatty acid.

32. THREE TYPES OF LIPIDS
It make up more
than 95 percent of
lipids in the diet and
are commonly
found in fried foods,
butter, milk, cheese,
and some meats
They are water-soluble and
are found in both plants and
animals. Phospholipids are
crucial for building the
protective barrier, or
membrane, around your
bodys cells.

33. LIPIDS
TRIGLYCERIDES
Are lipids that contain glycerol backbone and 3 fatty
acids. The 3 fatty acids connected to the glycerol
backbone are not necessarily of the same kind. Fat
and oils are example of triglycerides. Fats are usually
from animal sources contain mostly saturated fatty
acid making it solid at room temperature. Oil refers
to a triglyceride from plant sources. It contains
unsaturated fatty acid and is liquid at room
temperature.

35. LIPIDS
PHOSPHOLIPIDS
Is another type of lipids that contains glycerol, two
fatty acids, and a phosphate group. Phospholipids ,
unlike other kind of lipids, it has a polar end
(hydrophilic end) which is the phosphate group and
non-polar end (hydrophobic end), the fatty acid
group. The dual prop?erty of liquid allows the
phospholipid to form a bilayer.
