5. STRUCTURE AND CLASSIFICATION OF LIPIDS.
PHOSPHOLIPIDS: A class of lipid that is a key component of all cell membranes, as they can form lipid biomarkers. Composition: It is composed of phospholipids. i. Glycerol: one molecule ii. Fatty acids: Two molecules. iii. Phosphoric acid: one molecule. When a nitrogen-containing phospholipid group is attached to the end of the phospholipid, it is called phosphatidylcholine. Phospholipids consist of two parts i) Chapter: The head is polar in nature, soluble in water (hydrophilic). n) Tails: Nature has a non-polar tail, insoluble in water (hydrophobic).
Washes: Wax lipids are derived. Wax is a fatty acid ester and chronic alcohol: The wax is composed of i) a long-chain fatty acid ... one molecules ii) long-chain alcohol with one hydroxyl group (-OH), i.e. Cylinder wax is hydrophobic in nature. They have a high melting point, solid at room temperature. it gives stability and declines. On the surfaces of parts of plants, e.g. The leaves and fruits produce a waterproof layer, reducing the rate of perspiration. Wax is also a layer of wax that covers the bodies of animals, e.g., slime, insects, etc.
STEROIDS: Steroids fall under the lipid categories: Steroids are derived from lipid composition: proper arrangement of 3 cyclohexyl rings and 1 cyclopentane ring, a total of 17 carbon atoms in four carbon rings. Steroids do not contain alcohol and fatty acids.
Steroids Examples of steroids: i) Cholesterol: an important factor in animal cells. The precursor of all hormonal molecules such as aldosterone, sex hormone, and vitamin D ii) Aldosterone helps regulate Na+ions in the blood iii) Sex hormones e.g. testosterone, progesterone, and estrogens help to preserve the characteristics of males and females.
TERPENOIDES: It contains a very different class of organic compounds. Terpenoids are lipid derivatives, soluble in fat and soluble in water. Don't use molecule acids like fats. Composite units which they call isoprenoid or isoprenes. Isoprene unit: Hydrocarbon containing five carbon atoms with a branched-chain structure. Isoprene units bind to each other through the condensation process resulting in different types of compounds, e.g. Carotenoids, terpenes, and rubbers, etc.
CAROTENOIDS: Carotenoids are yellow, orange, red, or brown in plants. There are two kinds: i) Carotene: ii) Xanthophylla, i) Carotene: Orange is the genus of carotene, with red color, beta carotene. carrot & rice. Breakdown of beta-carotene leaves two molecules of vitamin A in the human body. n) Xanthophyllus: the auxiliary yellow color found in plants.

Here is a brief overview on the chapter Fats and Oils for BPharma students. It is an organic chemistry topic. All the definitions along with chemical reactions are mentioned and explained in an easy way.
The ability to recreate computational results with minimal effort and actionable metrics provides a solid foundation for scientific research and software development. When people can replicate an analysis at the touch of a button using open-source software, open data, and methods to assess and compare proposals, it significantly eases verification of results, engagement with a diverse range of contributors, and progress. However, we have yet to fully achieve this; there are still many sociotechnical frictions.
Inspired by David Donoho's vision, this talk aims to revisit the three crucial pillars of frictionless reproducibility (data sharing, code sharing, and competitive challenges) with the perspective of deep software variability.
Our observation is that multiple layers — hardware, operating systems, third-party libraries, software versions, input data, compile-time options, and parameters — are subject to variability that exacerbates frictions but is also essential for achieving robust, generalizable results and fostering innovation. I will first review the literature, providing evidence of how the complex variability interactions across these layers affect qualitative and quantitative software properties, thereby complicating the reproduction and replication of scientific studies in various fields.
I will then present some software engineering and AI techniques that can support the strategic exploration of variability spaces. These include the use of abstractions and models (e.g., feature models), sampling strategies (e.g., uniform, random), cost-effective measurements (e.g., incremental build of software configurations), and dimensionality reduction methods (e.g., transfer learning, feature selection, software debloating).
I will finally argue that deep variability is both the problem and solution of frictionless reproducibility, calling the software science community to develop new methods and tools to manage variability and foster reproducibility in software systems.

DERIVATION OF MODIFIED BERNOULLI EQUATION WITH VISCOUS EFFECTS AND TERMINAL V...Wasswaderrick3
In this book, we use conservation of energy techniques on a fluid element to derive the Modified Bernoulli equation of flow with viscous or friction effects. We derive the general equation of flow/ velocity and then from this we derive the Pouiselle flow equation, the transition flow equation and the turbulent flow equation. In the situations where there are no viscous effects , the equation reduces to the Bernoulli equation. From experimental results, we are able to include other terms in the Bernoulli equation. We also look at cases where pressure gradients exist. We use the Modified Bernoulli equation to derive equations of flow rate for pipes of different cross sectional areas connected together. We also extend our techniques of energy conservation to a sphere falling in a viscous medium under the effect of gravity. We demonstrate Stokes equation of terminal velocity and turbulent flow equation. We look at a way of calculating the time taken for a body to fall in a viscous medium. We also look at the general equation of terminal velocity.
Richard's aventures in two entangled wonderlandsRichard Gill
Since the loophole-free Bell experiments of 2020 and the Nobel prizes in physics of 2022, critics of Bell's work have retreated to the fortress of super-determinism. Now, super-determinism is a derogatory word - it just means "determinism". Palmer, Hance and Hossenfelder argue that quantum mechanics and determinism are not incompatible, using a sophisticated mathematical construction based on a subtle thinning of allowed states and measurements in quantum mechanics, such that what is left appears to make Bell's argument fail, without altering the empirical predictions of quantum mechanics. I think however that it is a smoke screen, and the slogan "lost in math" comes to my mind. I will discuss some other recent disproofs of Bell's theorem using the language of causality based on causal graphs. Causal thinking is also central to law and justice. I will mention surprising connections to my work on serial killer nurse cases, in particular the Dutch case of Lucia de Berk and the current UK case of Lucy Letby.

triglycerides that are liquid
at room temperature.
6. A type of Lipid : Fatty
substance does not dissolve
in water.
FATS are ESTERS formed through
reaction between Fatty Acid
and Glycerol.
GLYCEROL propan-1,2,3-
triol.
Fatty Acid
Long chain Carboxylic acids.
8. Visible Fat…
Fat that is easily seen
Examples: Butter on a baked
potato, layer of fat around a
pork chop, etc.
9. Invisible Fat
Fat that cannot be
detected by the eye
Examples: whole milk, some
cheese, egg yolks, nuts,
avocados, etc.
10. ESSENTIAL PART of HEALTHY
DIET.
MAJOR Source of ENERGY.
Critical component of CELLS
and TISSUES.
Absorb Vital VITAMINS
such as vitamin A,D,E and K
11. Promotes normal cell growth
and healthy skin.
Adds flavour to food.
It helps you feel full longer.
Act like a CUSHION and heat
regulator to protect your
heart , liver and other vital
organs.
12. Organic Acid units that
make up fat.
There are three types...
Saturated
polyunsaturated
monounsaturated
17. Exercise
Replace saturated fats with
unsaturated fats in the diets.
Choose lean(thin) cut of meat.
Steam , boil or steam food
instead of cooking them in fat.
18. Oils are natural occurring
esters.
Oils are found in both animals
and plants.
Oils are usually flammable.
19. Oils are ester formed by the
combination of
GLYCEROL FATTY ACID
21. The acid value indicates the
amount of free acids present in
given fat/oil.
A high acid value implies that
the given sample of oil is an
old one which has gone rancid.
22. There are three type of oils -
Saturated
Unsaturated
Margarine
23. Saturated...
There are only carbon-carbon
single bond.
Saturated plant oils are solid
at room temperature and also
known as vegetables fat.
Example:- PALM OIL
24. Unsaturated...
It contains single as well as
double covalent bonds.
Within the structure of fatty
acid tail a monounsaturated
oil has only ‘single’
double bond where as
in polyunsaturated oils
more than ‘one’ double bonds.
25. Margarine....
Most unsaturated oils are
liquid at room temperature.
These unsaturated oils can be
“hydrogenated” through a
process called hydrogenation.
Hardens the oil and is a key
step in the production of
margarine(solid or semi-solid).
26. In the laboratory one can
differentiate between saturated
unsaturated oil.
BY TESTING with BROMINE WATER
SATURATED UNSATURATED
will
It remain same. Its colour will decolorize.
27.
28.
29. Soap and Detergents are used for
washing.
It dissolves dirt, but some dirt
will not dissolve in water.
Soap and detergents help water
to remove dirt.
DETERGENT the KING,
DIRT the SLAVE....
30. Detergents are sodium salts of
long chain benzene sulphonic
acid or sodium salts of long
chain alkyl hydrogen sulphate.
A detergent molecule consists of
a large hydrocarbon group that
is non-ionic and a sulphonate
(SO3- Na+) or a sulphate (SO4-
Na+) group that is ionic.
32. There are two types of detergents:-
Soap-less detergent or
(synthetic detergents).
Soapy detergents or (soap).
33. Soap-less Detergent...
Soap-less detergents includes
Washing powders , washing-up
liquids, shampoos and hair
conditioners.
They are called ‘soap-less’
because they did not contain
soap.
36. PROPERTIES OF DETERGENTS:-
Detergent anions attract to both
water and oil.
This dual nature explains two
important properties of
detergents
1.Wetting property.
2.Emulsifying property.
37. Wetting property...
A detergents reduces the surface
tension of water. As a result of
this , water spread over the
surface and wets it more easily.
A detergent thus acts as a
wetting agent.
38. Emulsifying property...
Oil and water do not mix. An oil
water emulsion is unstable.
On standing, the tiny oil
droplets rapidly join together
and grow larger to form a
separate oily layer again.
39. An oil water emulsion is stabilised by
detergent:-
40. Comparing soaps and
soap-less detergents...
Comparing cleaning abilities in soft water and
hard water:-
Water may be soft or hard. Soft
water contains no or only very
small concentrations of dissolved
calciummagnesium ions.
Hard water contains appreciable
concentrations of calcium and
magnesium ions.
42. They do not form scum with hard
Water.
Soap-less detergents are made
from petroleum products , not
from fats and oils.
Soap-less detergents can be
tailor-made to suit a particular
cleaning problem.
43. • Detergents are non biodegradable.
• They pollute water and soil.
• Detergents may cause skin
allergy.
• More water rinses to remove foam,
otherwise it will damage the
fabric.
