Here I present:”Biochemistry’ for the Blind“.
Central idea of this blog post is《Body-space is where “what a molecule feels like” lives.》.
Biochemistry Blind equates Braille’ dots with Chinese acupoints (diagram ABOVE) .
INTRODUCTION.
Biochemistry’ here is a learning model keep it spatial-first, but not visual-first of three (3) blind spatial zones referred to as: Body-space → Immediate-space → Navigational-space.
Think of biochemistry’ as events moving outward from the body, not pictures on a page.
1️⃣ Body-space (Acupoints).
“Inside me / on me”
Sensory meaning
Proprioception
Touch
Internal timing (heartbeat, breathing)
Muscle tension
Biochemistry’ mapped here:
This is molecular experience.
Use body metaphors that are physically felt:
Concept: Body-space mapping.
Amino acids: Individual finger shapes.
Peptide bond: Fingers interlocking.
Protein folding: Hands twisting into a stable grip.
Disulfide bond: Two fingers tied together.
Enzyme specificity: One hand only fits one grip.
Hormone: Internal signal, like hunger.
Example: Somatostatin
SST-14 = small loop held between fingers.
Disulfide bond = rubber band connecting two fingers.
Inhibition = hand placed gently over another hand to stop motion.
> Body-space is where “what a molecule feels like” lives.
2️⃣ Immediate-space (Peripersonal space).
“Within arm’s reach”
Sensory meaning
Hand exploration
Object size, texture, resistance
Cause → effect by contact’.
Biochemistry’ mapped here.
This is interaction space.
Use tactile objects and motion:
Concept: Immediate-space mapping.
Ligand–receptor: Key entering lock.
Binding affinity: Strength of magnet pull.
Competitive inhibition: Two hands reaching for same object.
Signal transduction: Object passed hand-to-hand
Cleavage: Breaking a snap-fit piece.
Example: Somatostatin receptors.
Receptor = stationary object
Hormone = movable object.
Binding = click or snap.
Inhibition = object prevents another from docking.
> Immediate-space answers:“What touches what?”
3️⃣ Navigational-space.
“Where I go”
Sensory meaning
Walking
Routes
Orientation
Memory of space
Biochemistry’ mapped here.
This is system-level physiology.
Think pathways as routes, not diagrams.
Concept: Navigational mapping.
Metabolic pathway: Walking route.
Feedback inhibition: Roadblock.
Hormonal axis: Multi-room journey.
Homeostasis: Staying centered in known area.
Disease: Wrong turn or blocked passage.
Example: Somatostatin in the body.
Hypothalamus → Pituitary → Body = three rooms in sequence.
Somatostatin acts like a gatekeeper who says “slow down” at multiple doors.
It does not act locally only — it controls traffic flow
> Navigational-space answers: “Where does this go and what does it affect?”
CONCLUSION.
Why this works for blind biochemistry’.
Visual chemistry relies on static diagrams.
Blind learning relies on dynamic spatial experience.
The three-zone model maps perfectly onto:
Blind spatial zones: Biochemical level.
1. Body-space: Molecular structure.
2. Immediate-space: Molecular interaction..
3. Navigational-space Physiological systems.
This avoids:
Over-verbalization.
Symbol overload.
Diagram dependency.
And it scales from peptide → pathway → organism.
Teaching rule of thumb
When introducing any biochemical concept, always ask:
1. Can it be felt on the body?
2. Can it be touched or blocked nearby?
3. Can it be walked through as a route?
If all three are answered, the concept will stick
