Yesterday’s Chatshaala began with a question,“What was your lunch today”.
The food that we eat can be a good starting to introduce the Biochemistry, Don’t you think ?
Topics that there in curriculum:
“MOLECULES AND THEIR INTERACTION RELAVENT TO BIOLOGY”
A. Structure of atoms, molecules and chemical bonds.
B Composition, structure and function of biomolecules (carbohydrates, lipids,
proteins, nucleic acids and vitamins).
C. Stablizing interactions (Van der Waals, electrostatic, hydrogen bonding, hydrophobic
interaction, etc.).
D. Principles of biophysical chemistry (pH, buffer, reaction kinetics, thermodynamics,
colligative properties).
E. Bioenergetics, glycolysis, oxidative phosphorylation, coupled reaction, group
transfer, biological energy transducers.
F. Principles of catalysis, enzymes and enzyme kinetics, enzyme regulation, mechanism of
enzyme catalysis, isozymes
G. Conformation of proteins (Ramachandran plot, secondary structure, domains, motif
and folds).
H. Conformation of nucleic acids (helix (A, B, Z), t-RNA, micro-RNA).
I. Stability of proteins and nucleic acids.
J. Metabolism of carbohydrates, lipids, amino acids nucleotides and vitamins.
Chatshaala discussion :2/03/2025
Questions are raised:
- what do we get from our daily food ?
Seethalakshmi says she only had 3 pieces of bread today .Does that satisfy all the nutrients essential for our body like Carbohydrates, Proteins,Lipids , Vitamins etc.
Connecting Biochemistry with Plant biology
How does a fruit develop?
What is the difference between a fruit and a seed?
Is the rice we eat a fruit or a seed?
What parts does a flower have?
What are the differences between a rice flower and a pea flower?

[02/03, 9:41 pm] Dhanraj CUBE: Technically, a fruit is the ripened ovary and associated bits containing seeds, while a seed is a ripened ovule, containing the embryo and enough stored food to sustain it through the process of germination and the early development of the seedling. Fruits can be broadly classified as fleshy fruits and dry fruits. Fruits and Seeds.

[02/03, 9:42 pm] Dhanraj CUBE: Modern Indian wheat flours are generally made using roller mills, known as ‘chakkis.’
Clean wheat is conditioned and cracked to separate the endosperm from the bran. Milling is done in four or five stages resulting in different composition and particle sizes; subsequent sorting produces whole meal (atta) and semolina-type (suji/sooji) flours and further milling and sifting through 600 mesh and bleaching results in maida flour.
Within these types, there are finer divisions such as high gluten, medium and low gluten flours.
Nutrition
Maida flour is low in protein and fiber due to bran removal during milling.
Typical composition of maida flour:2
Flour Protein (%) Carbohydrate (%) Fat (%) Moisture (%) Fiber (%)
Maida 10.62 76.61 0.86 10.9 0.35
There has been a controversy regarding bleaching maida flours with alloxan, a substance banned by the Food Safety and Standards Authority of India (FSSAI). The chemical is a beta-cell killer and can cause diabetes in humans.3 Maida Flour | Baking Ingredients | BAKERpedia

[02/03, 9:43 pm] Dhanraj CUBE: Botanically, a cereal grain, such as corn, rice, or wheat is a kind of fruit (termed a caryopsis). However, the fruit wall is thin and fused to the seed coat, so almost all the edible grain-fruit is actually a seedhttps://en.m.wikipedia.org/wiki/Fruit#:~:text=Botanically%2C%20a%20cereal%20grain%2C%20such,fruit%20is%20actually%20a%20seed
[02/03, 9:43 pm] Dhanraj CUBE: Cereal grains like rice, corn, and wheat are technically a type of fruit called a caryopsis. In this type of fruit, the seed is tightly attached to the outer covering, so you can’t easily tell them apart. Even though it’s a fruit in science, we call it a seed because that’s the part we eat. So, while these grains are fruits in botanical terms, we treat them as seeds in everyday life.

[02/03, 9:59 pm] Dinesh Datta CUBE: Maybe botanically its a fruit?
Culinarily its a grain?cerealm
[02/03, 10:00 pm] Dinesh Datta CUBE: But i dont understand…
Can we call dried or fried rice as dry fruit?
[03/03, 8:50 am] Priti CUBE: Also maida has highest gluten
[03/03, 8:52 am] Priti CUBE: Is it a fused fruit and seed?
