Warning Signs of Low Calcium You Shouldn’t Ignore!
Here are 10 Signs That You Have Low Calcium Levels in Your Body
Calcium is crucial for maintaining strong bones and proper muscle function. When calcium levels in the body drop, it can lead to various health issues. Here are 10 key signs that may indicate you have low calcium levels (hypocalcemia):
Muscle Cramps and Spasms
Muscle cramps, especially in the legs, arms, and back, can be a sign of low calcium. These spasms often occur at night and may cause discomfort.
Tingling Sensations
Feeling tingling or numbness, especially in the fingers, toes, and face, is a common symptom of low calcium. This happens due to nerve sensitivity.
Brittle Nails
Low calcium levels can weaken nails, making them brittle, thin, and prone to breakage.
Fatigue
Chronic fatigue, lethargy, and weakness can result from calcium deficiency, as the body struggles to support muscle and nerve functions.
Tooth Decay
Calcium helps in maintaining healthy teeth. A lack of it can lead to weakened tooth enamel, increasing the risk of cavities and decay.
Dry Skin
Calcium is important for skin health. Deficiency may cause dry, scaly, and itchy skin.
Hair Loss
Prolonged calcium deficiency can contribute to hair loss, thinning hair, and slow hair growth.
Frequent Bone Fractures
A long-term lack of calcium weakens bones, making them more susceptible to fractures and osteoporosis.
Irregular Heartbeat
Calcium is necessary for heart function. A deficiency can lead to palpitations or an irregular heartbeat.
Mood Changes
Low calcium levels can affect mental health, causing symptoms such as irritability, anxiety, depression, or confusion.
How to Maintain Healthy Calcium Levels
To avoid these symptoms, ensure you consume calcium-rich foods like dairy products, leafy greens, almonds, and fortified cereals. If needed, consult your healthcare provider about calcium supplements.
Maintaining optimal calcium levels is essential for your overall well-being, so pay attention to these signs and take action early.

Lesson on the Inositol Trisphosphate (IP3) and Calcium Signaling Pathway. IP3, calcium and diacylglycerol (DAG) are important second messengers that are unregulated upon activation of a G protein-coupled receptor. Inositol triphosphate and DAG are cleavage products of phosphatidyl inositol 4,5 bisphosphate (PIP2), which is cleaved by phospholipase C. Increasing levels of IP3 lead to augmented cytosolic calcium levels that further lead to activation of downstream cellular targets.
Hey everyone. In this lesson you will be introduced to the IP3 and calcium signaling pathway. We will also discuss the purpose of the pathway, enzymes involved in the pathway, and how the pathway is regulated.

IP3-mediated signal transduction pathways
First messengers are extracellular signaling molecules, such as hormones or neurotransmitters. In response to exposure to these first messengers, intracellular signaling molecules called second messengers are released by the cell. Two such second messengers are IP3 and DAG.
Calcium is also an important second messenger. Transient increases in cytoplasmic Ca2+ levels are caused by the binding of some hormones and signal molecules, and this can send important intracellular signals, by activating calcium-binding proteins that then perform various functions. Note that cytosolic increases in calcium concentration can occur in two ways. There are reservoirs of calcium that can be opened within the cell by the second messenger IP3 – the endoplasmic reticulum and calciosomes. Otherwise, cyclic AMP can activate the opening of calcium channels in the plasma membrane so that extracellular calcium can rush in.
G-protein-coupled receptors, or GPCRs, are integral membrane proteins, meaning that they are locked into the cell membrane. They are locked in via 7 transmembrane α-helical segments. GPCRs recognize ligands through an extracellular recognition site. They also have an intracellular recognition site for a G protein. When a ligand binds the extracellular recognition site of a GPCR, this induces a conformational change, activating the G-Protein.
There are different kinds of G proteins, sometimes also called membrane-associated heterotrimeric G proteins. Gs activates adenylyl cyclase. Gi inhibits adenylyl cyclase.
Gq has three subunits – α, β, and γ. A conformational change in the GPCR activates the G protein. When this happens, the GDP on the Gα subunit gets replaced by GTP. This drives dissociation of the Gα subunit from the Gβγ complex. The now free Gα subunit can activate Phospholipase C-β.
Phosphatidylinositol-4-P (PIP) and phosphatidylinositol-4,5-biphosphate (PIP2) are produced through successive phorphorylations of phosphatidylinositol (PI). Once it is activated by a G-protein, Phospholipase C-β can break down PIP2.
PIP2 is hydrolyzed by phospholipase-C to produce inositol-1,4,5-triphosphate (IP3) and diacylglycerol (DAG), both of which act as second messengers. IP3 is hydrophilic, and diffuses into the cell, while DAG is lipophilic, and hence remains in the cell membrane. IP3 binds to calcium channel on endoplasmic reticulum (or the sarcoplasmic reticulum in the case of muscle cells) and allows release of calcium from the endoplasmic reticulum lumen. DAG, with the help of the calcium released from the endoplasmic reticulum, activates the calcium-dependent Protein Kinase C. Once activated, protein kinase C adds phosphates to target proteins and causes cellular responses.
Explanation of how to find the molar mass of Ca(OH)2: Calcium hydroxide.
A few things to consider when finding the molar mass for Ca(OH)2:
– make sure you have the correct chemical formula.
– always include the units for molecular weight (grams/mole).
– make sure you do the math right – follow the order of operations.
Watch: Molar Mass in Three Easy Steps: https://youtu.be/o3MMBO8WxjY
Note that molecular weight, molar mass, and gram formula mass are essentially the same concept.
Finding the Molar Mass (sometimes called Molecular Weight although the units are different) of a compound is a essential skill for the chemistry topic of stoichiometry and the first step in converting from moles to grams (or grams to moles).
For more chemistry help visit http://www.Breslyn.org .
—
Using the Periodic Table look up the atomic weight of each of the elements in Ca(OH)2. In most cases is it appropriate to round to two decimal places when finding the molecular weight for Ca(OH)2 (unless you were told to do otherwise). For molar mass for Ca(OH)2 (molar mass and molecular weight are the same thing) just add the atomic weights.
Note that for Ca(OH)2 you need to be sure and apply the subscript 2 to both the O and H. In other words you have two oxygen atoms and two hydrogen atoms.
In this video we’ll write the correct formula for Calcium acetate: Ca(CH3COO)2.
To write the formula for Calcium acetate we’ll use the Periodic Table, a Common Ion Table, and follow some simple rules.
Because Calcium acetate has a polyatomic ion (the group of non-metals after the metal) we’ll need to use a table of names for common polyatomic ions, in addition to the Periodic Table.
Keys for Writing Formulas for Ternary Ionic Compounds:
1. Write the element symbol for the metal and its charge using Periodic Table.
2. Find the name and charge of the polyatomic ion on the Common Ion Table (see https://youtu.be/N4N1Njh7nCo).
3. See if the charges are balanced (if they are you’re done!)
4. Add subscripts (if necessary) so the charge for the entire compound is zero.
5. Use the crisscross method to check your work.
Notes:
– Don’t write the subscript ‘1’.
– If you use the criss-cross method and end up with something like Ca2S2 you’ll need to reduce the subscripts to Ca1S1 which we write CaS.
Note: It is possible to have two polyatomic ions such as NH4NO3. In this case find and write both names as found on the Common Ion Table.
