Place a slice of a potato on a paper towel atop a paper plate and add a drop of the iodine solution to the potato slice.
A solution of corn starch in water (left) turns purple while the milk (right) remains unchanged. Starch is a carbohydrate and exists in two types of molecules: amylose (linear) and amylopectin (branched). Many details of the reaction of iodine with starch are unknown, but one explanation is that when a solution of diluted iodine is added to starch, an intensely colored starch-iodine complex forms. Amylose molecules consist of single, mostly unbranched chains of glucose molecules, shaped like a spring. Note: The effect is only seen when both iodine as an element and iodide as an ion are present. Amylopectin, having a branching structure, reacts with iodine to form a reddish brown or purple solution. Foods that are high in starch include grain foods and some vegetables, such as dried beans and peas, potatoes, yams, and corn. Although squats and lunges are both key for a toned backside and legs, there are slight differences between the two. Rather than the up and down motion of a squat, lunges require a step forward or backward with one leg, lowering your hips until both knees are bent at about a 90-degree angle. If you're just starting to get your backside into shape, then consider squats your go-to exercise. Remember, when doing both squats and lunges, it is important to pay close attention to your form. Google Home also works with Google Cast and lets you do things like control any speaker in your home. Chocolate chip cookies like these are addicting, so throw away the scale and make extras for the cookie jar! You can use Betadine (a povidone-iodine mixture), Lugol’s solution (an iodine-potassium mixture), or tincture of iodine (here the iodine is dissolved in alcohol, or alcohol and water), depending what is available. Most starch contains a mixture of these two molecules, generally with more amylopectin (65% to 85%).


It is speculated that the iodine (in the form of I5- ions) gets stuck in the coils of the beta amylose molecules (soluble starch). Since amylopectin is highly branched, it only binds a small amount of iodine and produces a paler purple-red color. In beer brewing, a negative starch test result confirms that all the starches in the beer have been converted to sugars, as expected. To maximize effectiveness and prevent injury, it's important you know the specifics of each exercise and do them just right. Because lunges involve the transfer of weight to one leg, they are a test of balance, especially when using weights, meaning your core gets a workout too!
Because they are a functional movement, squats are a good introduction to the weight room; it's easy to add weight or resistance to the exercise, which quickly helps to increase strength.

Using a mixer; cream together the butter, milk, brown sugar, and white sugar until thoroughly blended.
Add in the egg, the egg yolk, and vanilla and mix until well blended and smooth (about 1 minute).
Add the chocolate chips, and mix until they are evenly distributed throughout the batter (about 30 seconds). Drop by rounded 2 Tablespoons (use a cookie scoop or combine 2 Tablespoons of dough into a rounded drop) onto the prepared cookie sheet, about 2 inches apart. DO NOT put iodine in your mouth and DO NOT eat any tested foods, as iodine can be poisonous. They all have a very strong color, so dilute the mixture with about 10 parts water to see the reaction more clearly. The reaction between amylose (even though it is often present in lesser amounts) and iodine is said to account for the intense color change seen.
The starch forces the iodine into a linear arrangement in the middle groove of the amylose coil.


Iodine, together with the iodide ion, forms a complex which dissolves in water, unlike iodine on its own. Unripe bananas contain a fair amount of starch, but ripe bananas don’t, as the starches have transformed to sugars. And depending on the variation, lunges can also allow for an increased focus on the glutes or inner thighs; do side lunges to work your hips or reverse lunges to counter the forward movements of everyday life. Since the weight is distributed onto your heels when doing squats, the exercise requires less balance than lunges.
Molecular iodine (I2) reacts with iodide (I-) which is a negatively charged ion and creates an anion (I3-). A ripe banana will not produce a bluish-black color with iodine, but you will see the effect in a greener banana. Instead, doing a squat is much like sitting down in a chair, making them a great exercise for working the glutes and hamstrings. If you you suddenly feel pain, then adjust the exercise or try a different variation until the pain gets better. For example, if you ask it "What movies are currently playing," the device will tell you and then follow up with where they are playing nearby. Depending on your depth and range of motion, lunges help to increase flexibility in your hips.
Turn squats into a quick cardio workout by adding jumps, or challenge your core with the addition of a BOSU ball.
The new spacings absorb visible light selectively and give the complex its intense blue color.
